What is steam?Steam is what water becomes when it's heated to boiling and begins to turn into a gas.Steam is the hotmist that forms when water boils. Steam vehiclesand machinesareoperated using steam as a meansof power.In an electric power plant the heat converts water into high-pressure steam - the inventionof 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. Themajor components of this power plant are boiler, steam turbine, condenserand water feedpump.The steam power plant is the important source to produce the electricity. The majorportion of electricity demand is fulfilled by the steam power plant. It is also called asthermal power plant. It provides the electricity requirement to different areas. In thisarticle we will study about the construction, working, efficiency, advantages anddisadvantages of steam power plant.Site Selection The site selection of steam power plant depends upon various factors. Let’s discuss aboutthese factors one by oneCost of the land: The cost of the land which is selected for the installation should beminimum or economical.Population density of the land: The distance of the steam power plant from the publicarea should be at appropriate distance. So that in case of any failure or hazard happen inthe 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 selectedarea. 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 becausewithout fuel the plant will not work.Type of land: The land which is selected for the power plant installation should be plainenough 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 thehandling of future power demand.Availability of Ash handling facility: Proper ash handling facility should be available nearthe power plant to minimize the adverse effect of the ash produced in the steam powerplantAvailability of transportation facility: The transportation facility is must in the installationfor the power plant, because any material cannot be transported to the power plant form1
its required location in lack of transport. There should be easy availability of propertransportation facility at the selected site.Construction or Layout of Steam Power PlantThere are so many components present in the steam power plant which performs theirspecialized function for the efficient working. The various component of the steam power plantare:Coal Storage: It is the place where coal is stored which can be utilized when required.
