What is steam? Steam is what water becomes when it's heated to boiling and begins to turn into a gas. Steam is the hot mist that forms when water boils. Steam vehicles and machines are operated using steam as a means of power. In an electric power plant the heat converts water into high-pressure steam - the invention of the steam engine. What is a steam power plant? It is the power plant which is used to generate electricity by the use steam turbine. The major components of this power plant are boiler , steam turbine, condenser and water feed pump. The steam power plant is the important source to produce the electricity. The major portion of electricity demand is fulfilled by the steam power plant. It is also called as thermal power plant. It provides the electricity requirement to different areas. In this article we will study about the construction, working, efficiency, advantages and disadvantages of steam power plant. Site Selection The site selection of steam power plant depends upon various factors. Let’s discuss about these factors one by one Cost of the land: The cost of the land which is selected for the installation should be minimum or economical. Population density of the land: The distance of the steam power plant from the public area should be at appropriate distance. So that in case of any failure or hazard happen in the plant, the population of the area near to the power plant should not be affected. Availability of water sources: There should be a plenty of water sources in the selected area. Since the power plant requires a large amount of water for the generation of steam. Availability of fuel: The availability of required fuel (coal) should be there because without fuel the plant will not work. Type of land: The land which is selected for the power plant installation should be plain enough and it is suitable for the strong foundation for the various machinery of the plant. Scope for the future demand: The size of the land should be such that it is capable for the handling of future power demand. Availability of Ash handling facility: Proper ash handling facility should be available near the power plant to minimize the adverse effect of the ash produced in the steam power plant Availability of transportation facility: The transportation facility is must in the installation for the power plant, because any material cannot be transported to the power plant form 1

its required location in lack of transport. There should be easy availability of proper transportation facility at the selected site. Construction or Layout of Steam Power Plant There are so many components present in the steam power plant which performs their specialized function for the efficient working. The various component of the steam power plant are: Coal Storage : It is the place where coal is stored which can be utilized when required.
