The setup cost is also very low compared to others.The fuel used is quite cheaper compared to other modes of power generation processes.The coal for the combustion is to be transported via railways and roadways.The advantages of Steam Power Plant are as follows. It can be used in the automotive industry.The uses of Steam Power Plant are as follows. In this way, the feed water rotates throughout the circuit with few losses of water, and the power is generated from the steam which is used to drive the turbines. The hot steam cannot be released directly into the atmosphere from the chimneys and by doing so, the hot steam will affect the atmosphere.įor this reason, the hot steam along with water particles was released from the larger heights in the cooling tower, so that the water will fall down and the air particles will escape into the atmosphere.Īfter burning of the coal, it is transported to ash handling plant and finally to the ash storage. The water that is used to condense the steam in the condenser was supplied from the cooling tower. This feedwater is sent to the boiler using a feed pump. The economizer must extract a part of the heat from the condensate by adding the feed water to increase the feedwater temperature before supplying it to the boiler. The condensed water(also known as condensate) along with the feedwater, enters into the economizer. mechanical energy of the turbine into electrical energy.Īfter striking the turbine, the steam enters into the condenser where it gets condensed with the help of cold water from the cooling tower. The generator converts one form of energy to another i.e. Thus the superheated steam strikes the turbine blades with a high speed which makes the turbine rotate.Ī generator is attached to the rotor of the turbine and as the turbine rotates, it also rotates with the speed of the turbine. The steam is taken from the boiler and is superheated so that, the steam present should be free from the water molecules. The water present in the boiler is heated up by means of a furnace and as the density of steam is less than the density of water, the steam will deposit on the surface of the water. Furnace Circuit:īefore feeding to the furnace, the coal is to be converted into the pulverized form and after combustion, the ash is to be collected into the Ash Pit (Ash handling unit). The explanation of these circuits is as follows. Working Principle of Steam Power Plant:Ī Steam Power Plant working phenomena will be discussed using 3 circuits: Let's understand the Working Principle of it. These are the various parts of the Steam Power Plant. It is the last stage where only the air particles will enter into the atmosphere by reducing the heat from steam by the usage of the water sprinklers. This feedwater is to be sent to the boiler using a feed pump only. The economizer adds the feed water to extract a part of the heat from the condensate by increasing the feedwater temperature. The steam after striking on the blades of the turbine enters into the condenser where it gets condensed with the help of cold water from the cooling tower. Generator:Ī generator that converts one form of energy to another is attached to the rotor of the turbine and as the turbine rotates, it also rotates with the speed of the turbine. The steam which is free from water molecules are used to strike the blades of the turbine so that large amount of power can be generated. The steam is taken out from the boiler and is superheated so that, the steam should be free from the water molecules. Utilization in industries like sugar mills, chemical industries, etc.The equipment used for producing steam is called Boiler or Steam Generator. Coal and Ash Handling Unit:īefore feeding the coal to the furnace, It is to be converted into the pulverized form and after the combustion, the ash is collected in the ash handling unit. The detailed explanation for the components of Steam power plant are as follows.
