Basic Layout and Working of a Thermal Power Plant Coal: In a coal based thermal power plant, coal is transported from coal mines to the generating station. Generally, bituminous coal or brown coal is used as fuel. The coal is stored in either 'dead storage' or in 'live storage'. Dead storage is generally 40 days backup coal storage which is used when coal supply is Steam Power Plant - Working Principle & Schematic Diagram Steam Power Plant: Here now we going to discuss only steam power station or steam power generation plant and all other power station in next coming articles have the advantages, disadvantage, layout, working principle of steam power station or steam power plant in this article. A generating station which converts heat energy of coal combustion into electrical energy is known as a steam Gas Turbine Power Plant - Layout & Schematic Diagram Gas Turbine Power Plant: Here I am going to explain you the different types of power generating stations or power plant. First, let us know what is the function of a power generating station. A power generating station or power plant uses various sources like hydel energy, thermal energy, diesel, nuclear energy to produce bulk electric power.
