    The difficulty was solved in Loeffler boiler by preventing the flow of water into the boiler tubes. Most of the steam is generated outside from the feed water using part of the super coming out from the boiler. Power Plant Engineering works at a high pressure of bars there is no danger of bubble formation even when sudden fall of demand occurs. Benson boiler can be started very quickly from cold. Demerits of Benson Boiler It has low steam, capacity and hence not suitable for high power outputs.

    There are possibilities of overheating of economizer, evaporator and super heater, in cases of feed water pump problems in running conditions. It cannot meet sudden, raise, in demand. The major difficulty experienced in Benson Boiler is the deposition of salt and sediment on the inner surfaces of the water tubes. This further increased the danger of overheating the tubes due to salt deposition acid has high thermal resistance.

    Most of the steam is generated outside from the feed water using part of the super The pressure feed pump draws the water through the economizer and delivers it into the evaporator drum as shown in the figure.

    The steam circulating pump draws the saturated steam from the evaporator drum and is through the radiant super heater and then connective super heater. The steam coming out from high pressure turbine is passed through re heater before supplying to Page 6 bars there is no danger of bubble formation even omizer, evaporator and super heater, in cases of feed The major difficulty experienced in Benson Boiler is the deposition of salt and sediment on the inner surfaces of the water tubes.

    The deposition reduced the heat transfer and ultimately the ating the tubes due to salt deposition The difficulty was solved in Loeffler boiler by preventing the flow of water into the boiler tubes.

    Power Plant Engineering Kiran Vijay Kumar This boiler can carry higher salt concentration than any other indirectly heated boilers having natural circulation. These qualities fit it for land or sea transport power generation. Loeffler boilers with generating capacity of Velox Boiler: Power Plant Engineering This boiler can carry higher salt concentration than any other type and is more compact than indirectly heated boilers having natural circulation.

    This boiler design makes use of pressurized combustion, to achieve a higher rate of heat transfer from a smaller surface area. The special feature of this boiler is that the flue gases are expanded in a gas turbine before being discharged to the atmosphere, which runs an axial flow compressor. The axial flow compressor is used to pressurize the atmospheric air to the operating furnace pressure to facilitate pressurized combustion. The compressor is driven by the gas turbine with reduction gears as the turbine speed is very This system thus makes efficient use of the fuel in a smaller area for heat transfer.

    In the steam line, the feed water from the economizer passes through a steam separating unit. The steam is separated due to the centrifugal effect of the water entering through the spiral The separated water is then fed to the evaporator by a water circulating pump. The steam separated in the separator as well as the steam from the evaporator together enters This superheated steam finally passes to the prime mover for operation.

The axial flow compressor is used to pressurize the atmospheric air to the operating furnace The compressor is driven by the gas turbine with reduction gears as the turbine speed is very This system thus makes efficient use of the fuel in a smaller area for heat transfer. Schmidt Hartmann Boiler Operation: A closed primary steam circuit is used to evaporate the water in the secondary circuit and the steam produced in the secondary circuit is used for running the prime mover.

    This is achieved by the submerged heating coils in the evaporator of the primary circuit condensate of this circuit is used to preheat the feed water of the secondary circuit, and finally flows back to the primary evaporator. The primary circuit also includes a steam separator and a non-return valve as shown in figure.

    This is achieved by the submerged heating coils in the evaporator of the primary circuit condensate of this circuit is used to preheat the feed water of the secondary circuit, return valve as shown in figure. Heat transfer rate is large. High thermal efficiency. Problem of corrosion and erosion are minimized.

    Adaptable to load fluctuations. It is costly due to increased requirement for steel for heat transfer surface, pump and feed water piping.

It is costly due to increased requirement for steel for heat transfer surface, pump and feed Generation of steam using forced circulation, high and supercritical pressure: Forced These boilers often use orifice, which control which control flow circulation.

    Power Plant Engineering Natural circulation boilers: Here the water is circulated purely by density difference with most of the heat from the fuel flame is being radiated to the water walls directly. The steam pressure of such boiler is limited to bar, with water steam being separated in boiler Forced circulation boilers: In these boilers water is circulated by using additional pump.

    These boilers can produce steam pressure up to bar. Page 10 Here the water is circulated purely by density difference with most of the heat from the fuel flame The steam pressure of such boiler is limited to bar, with water steam being separated in boiler In these boilers water is circulated by using additional pump.

    These boilers often use orifice, bottom of tubes that ensure eve distribution of flow through water wall tubes. Power Plant Engineering Once through boilers: These boilers operate about critical pressure i. As density of water and steam is same above critical pressure, there will be no recirculation. In these boilers water enters bottom of the tubes and completely transforms into steam as it pass through tubes and reaches the top.

    Thus, these boilers does not require steam drum and hence referred to as drumless boilers. Page 11 As density of water and steam is same above critical pressure, there will be no recirculation. In these boilers water enters bottom of the tubes and completely transforms into steam as it pass Thus, these boilers does not require steam drum and hence referred to as drumless boilers. Accessories For The Steam Generator such as super-heaters, desuperheater, control of super heaters, Economisers, Air Pre- heaters Study of different types of cooling towers and ponds.

    Chimney is a tall hollow structure, which creates the required draught due to difference in pressure from the ground level to some altitude in the atmosphere. Draught or Draft system: Natural Draught 2. Natural Draught: Mechanical Draught: It is caused by the density difference between atmospheric air and hot gas in the stack.

    It requires small capital investment. The exhausts are discharged at a high altitude and -hence atmosphere pollution is less at lower The system has a long life. The maximum pressure created by natural draught is very low 20mm of water. For sufficient draught, the flue gases should be discharged at a higher temperature, which reduces the plant efficiency. Economizer and pre heater cannot be used to recover heat from the flue gases.

    The system will have poor combustion efficiency, since the velocity of air is low. It cannot produce higher draughts under peak loads, hence not flexible. There are two types of mechanical draught systems, depending upon the type of fan used for creating the draught effect. If a forced draught fan is used it is termed a forced draught system, and if an induced draught fan is used it is termed an induced draught system. Page 13 It is caused by the density difference between atmospheric air and hot gas in the stack.

    For sufficient draught, the flue gases should be discharged at a higher temperature, which Economizer and pre heater cannot be used to recover heat from the flue gases.

    There are two types of mechanical draught systems, depending upon the type of fan used for system, and if an induced Power Plant Engineering Forced Draught: The blower forces the air through the furnace, economizer, air preheater and finally to the stack. This system is termed a positive or forced draught system, since the pressure throughout the system is above atmospheric, and the flues are force driven.

    The function of chimney in this arrangement is only to discharge the exhaust at high altitudes. The chimney has got nothing to do with draught creation and hence its height need not be too much, but a higher altitude is desirable to discharge the flues to minimize atmospheric pollution.

    Induced Draught: The action of induced draught is similar to the action of natural draught chimney, but the draught produced it independent of the temperature of hot gases.

    Page 14 The blower forces the air through the furnace, economizer, air preheater and finally to the stack. This system is termed a positive or forced draught system, since the pressure throughout the The function of chimney in this arrangement is only to discharge the exhaust at high altitudes.

    The action of induced draught is similar to the action of natural draught chimney, but the draught heat can be recovered in the air pre heater and economizer, and comparatively In the induced draught, the pressure is below atmospheric suction , chances of leakage. Advantages of Mechanical Draught over Natural Draught 1 In a mechanical draught system, the rate of combustion is high since high draught is available. Power Plant Engineering Balanced Draught: Forced draught supplies sufficient air for combustion and induced draught prevents blow off flames when the doors are opened Comparison between Forced Draught and Induced Draught Systems: Water cooled bearings are required in induced draught system since the hot gases come in contact with the There are chances of air leakage in the forced draught system, since the pressure inside the furnace is above atmospheric.

    In the induced draught, the pressure is below atmospheric suction , In the induced draught system, air flow is more uniform through the grate and furnace, as compared to the In an induced draught system, cold air may rush into the furnace while fuel charging d This cold air rush will reduce the heat transfer efficiency. The fan blade wear is more in induced draught system as the blades come in contact with hot gases.

    Advantages of Mechanical Draught over Natural Draught: The rate of air flow, hence the combustion can be controlled by changing the draught pressures through the The operation of the mechanical draught system does not depend on the environmental temperature.

    However, the natural draught is highly dependent on the environmental temperature. Low grade fuels can be easily burnt in mechanical draught system since a higher level of draught is in a mechanical draught system. In mechanical draughts, maximum heat can be recovered and hence the overall efficiency is higher. The chimney height need not be as high as that of natural draught as its function is only to discharge the Page 15 Balanced draught is a combination of both forced draught and induced draught.

    In the induced draught, the pressure is below atmospheric suction , hence there are no In the induced draught system, air flow is more uniform through the grate and furnace, as compared to the In an induced draught system, cold air may rush into the furnace while fuel charging doors are opened. In a mechanical draught system, the rate of combustion is high since high draught is available.

Low grade fuels can be easily burnt in mechanical draught system since a higher level of draught is In mechanical draughts, maximum heat can be recovered and hence the overall efficiency is higher.

    The chimney height need not be as high as that of natural draught as its function is only to discharge the Some of the essential boiler accessories as follows, 1. Super heater 2. Re heater 3. Economizer 4. Air pre heater Other essential accessories include: De super heater 2. Soot blower 1. Super heater: Power Plant Engineering A boiler requires many accessories for continuous trouble-free functioning and steam Some accessories are needed to increase the efficiency of the boiler.

    High economy in power generation can be achieved by utilizing the heat ene Some of the essential boiler accessories useful for waste heat recovery, in the sequence, are Other essential accessories include: If used directly, the water particles in the wet steam cause corrosion of the turbine blades, lead to reduced turbine efficiency, life and later failure of the blades itself The super heater completely saturates the wet steam produces dry steam and increases its temperature.

    A superheated steam has high heat content, and hence has an increased capacity to do work. This in turn improves the overall efficiency of the power plant. The super heaters are made of steel tubes of 25 to 50 mm diameter, and formed in series of U Super heaters can be classified based on the heat transfer method.

    There are three types of super heaters, as follows: Page 16 free functioning and steam High economy in power generation can be achieved by utilizing the heat energy to the , in the sequence, are the steam coming from The steam generated in a boiler is not fully saturated, it contains some water particles If used directly, the water particles in the wet steam cause corrosion of the turbine blades, cy, life and later failure of the blades itself The super heater completely saturates the wet steam produces dry steam and increases its A superheated steam has high heat content, and hence has an increased capacity to do work.

    The super heaters are made of steel tubes of 25 to 50 mm diameter, and formed in series of U Power Plant Engineering super heater- Absorbs heat from the hot gases by convection. This is the primary super heater that receives nearly saturated steam from the boiler drum. This super heater is located in the convective zone of the furnace, just before the economizer. Absorbs heat from the hot gases by radiation. This is the secondary super heater that receives steam from the primary super heater.

    This super heater is located in the radiant zone of the furnace, adjacent to tile water wall so that it absorbs heat by radiation. Combined convective and radiant super heater - Absorbs heat both by convection and radiation from the hot gases. This is also termed the pendant super heater, and is another secondary super heater used in Usually the steam from the radiant super heater passes through a de super heater, where high quality water is directly sprayed on to the steam.

    The de super heater maintains the required temperature in the steam after passing through the stage or the pendant super heater. In a boiler, the super heaters are used to superheat the steam before being expanded in the high The steam from the HP turbine loses the pressure and temperature.

    This steam before being sent to the next stage intermediate IP or low pressure LP turbine, it need to be improved again, this is done by passing this steam through a re heater.

    A re heater is generally located above the primary or convective super heater in the path of the hot s mounted horizontally, perpendicular to the flue direction. Page 17 This is the primary super heater that receives nearly saturated steam from the boiler drum.

    This super heater is located in the radiant zone of the furnace, adjacent to tile water wall so This is also termed the pendant super heater, and is another secondary super heater used in iant super heater passes through a de super heater, where high quality water is directly sprayed on to the steam.

    Advantages of Economizer 1 It recovers the waste heat to a greater extent. The economizer makes use of waste flues; recovers heat energy and hence the name economizer.

    Thus the economizer increases the boiler efficiency. The feed water pump pumps either raw water after proper treatment or condensate from the The feed water flowing through the economizer gets heated and enters the boiler under return valve is provided to avoid return flow of feed water or steam from the boiler, when the feed pump is not in operation.

    The pump pressure is always higher about 2 bar more the boiler pressure in operation. Advantages of Economizer: The feed water pump pumps either raw water after proper treatment or condensate from the The feed water flowing through the economizer gets heated and enters the boiler under eed water or steam from the boiler, The pump pressure is always higher about 2 bar more the boiler pressure in operation.

    Air pre heater: Special accessories, 1. This makes use of the flues discharged from the furnace and from the economizer. As this also recovers further heat from the flues, it increases the boiler efficiency. Page 19 The function of an air preheater, as the name indicates, is to preheat the air being supplied to This makes use of the flues discharged from the furnace and from the economizer.

    When the temperature of the superheated steam raises sufficiently high, then the hot gases are bypassed with the help of dampers. Cooling Towers: Wet type a Natural draught cooling tower b Forced draught cooling tower c Induced draught cooling tower 2.

    Dry type a Direct type b Indirect type 1. Wet type: The device used to control the superheat temperature is termed a desuperheater The various methods used to control the superheat temperatures are as follows: The quantity of cooling water required is so high that it cannot be let out after use.

    A MW plant needs about 10, tones of cooling water per day. The used water absorbs heat from the condenser and cannot be recirculated unless cooled to a The different types of cooling towers used in power plants are: It consists of a huge hyperbolic concrete structure, with openings at the bottom.

    At the lowest portion of the structure a water pond is constructed for the collect In operation, the cooling water from the condenser is to the top of the cooling tower.

    The water is sprayed from the top, and falls sprinkles. Because of the height, natural draught is created and the air rises bottom. Make up water is added to the pond periodically. The height of the cooling tower ranges from 50 m to 80 m, with base diameter Page 20 It is essential to control the superheat temperature, otherwise it may lead to overheating of superheated tubes and initial stages of the turbine, causing operational problems.

    The device used to control the superheat temperature is termed a desuperheater. The various methods used to control the superheat temperatures are as follows: When the temperature of the superheated steam raises sufficiently is essential in a steam power plant to condense the steam from the steam turbines. The used water absorbs heat from the condenser and cannot be recirculated unless cooled to a This is a wet type of cooling tower, and is generally used in large capacity power plants.

    At the lowest portion of the structure a water pond is constructed for the collection of the In operation, the cooling water from the condenser is to the top of the cooling tower.

    Power Plant Engineering Forced draught cooling tower: Since the height of the cooling tower is smaller and it has a rectangular section, the natural draught created very low. A forced draught fan is provided at the bottom, and it pressurizes the air. The cooled water is collected in the pond and re circulated. Make up water is added to the pond periodically Induced draught cooling tower: It has a rectangular section with opening at the bottom for the air entry.

    In operation the induced draught fan sucks air through the baffles from the openings at the The hot water pumped from the condenser is sprayed at the top. The falling water comes in contact with the raising air and gets cooled. Make up water is added periodically to the pond. Page 21 Forced draught cooling towers are smaller in size and are used in small capacity power plants. The hot water from the condenser is sprayed from the top and while falling through the aught air and gets cooled.

    This is similar in construction and operation to a forced draught cooling tower, except for the In operation the induced draught fan sucks air through the baffles from the openings at the cooled water is collected in the pond and pumped back to the condenser. Dry type: The steam tubes are provided with external fins, so as to increase the heat transfer rate and hence condense the steam in the tubes. There are two types of indirect dry cooling towers.

    Indirect dry cooling tower with a open type condenser The construction and operation of this cooling tower is same as the dry indirect cooling tower with surface condenser, except that it uses a open spray type condenser instead of the surface Thus this cooling tower also uses two heat exchangers in series.

    The first one is a direct contact spray type steam condenser, where the turbine exhaust steam is condensed using cooling water. The second heat exchanger is indirect type, the hot water to air heat exchanger, in which the hot water from the condenser is cooled with the help of finned tubing similar to the dry cooling tower concept.

Since the heat is absorbed by the cooling he air gains temperature from T These temperature path lengths at the condenser and the cooling tower. The water that would go over the dam spill-way unused during low-loads can be released and added to normal river flow to supply peak loads, usually for a few hours of duration For fluctuating loads, pondage increases the maximum capacity that a plant can carry.

    Pondage increases the capacity of a river for a brief period only, like for 8 week. But, storage increases the capacity of a river over an extended period such like 6 months to 2 Page 24 ger by mixing with steam, the water temperature raises from T1 to T2 then passed through a series of steel tubes in the drying tower. The amount of regulation obtained with pondage usually involves storing water during low loads during low power demand periods such as early morning hours and Sundays to aid loads can be released and added to normal river flow to supply peak loads, usually for a few hours of duration For fluctuating loads, pondage increases the maximum capacity that a plant can carry.

    Thermal power plants[ edit ] Coal being pushed into coal power plant Thermal power plants are split into two different categories; those that create electricity by burning fuel and those that create electricity via prime mover. A common example of a thermal power plant that produces electricity by the consumption of fuel is the nuclear power plant. Nuclear power plants use a nuclear reactor's heat to turn water into steam.

    Mechanical engineers maintain performance of the thermal power plants while keeping the plants in operation. Photovoltaic panels, or solar panels , are constructed using photovoltaic cells which are made of semiconductor materials that release electrons when they are warmed by the thermal energy of the sun.

    The new flow of electrons generates electricity within the cell. Wind power plants can be implemented on large, open expanses of land or on large bodies of water such as the oceans; they simply rely on being in areas that experience significant amounts of wind. Knowledge of fluid dynamics from the help of mechanical engineers is crucial in determining the viability of locations for wind turbines.

    The field can solicit information from mechanical, electrical, nuclear, and civil engineers. Mechanical[ edit ] Mechanical engineers work to maintain and control machinery that used to power the plant. The Mechanical Engineers have additional roles that are needed to be considered based on their career.
