A steam power plant must have the following equipment. 1. A furnace for burning the fuel. 2. A steam generator or boiler for steam generation. 3. A power unit like an engine or turbine to convert heat energy into mechanical energy. 4. A generator to convert mechanical energy into electrical energy. 5. Piping system to carry steam and water.
in a power plant are typically steam or combustion turbines, diesel engines, or electric motors. Heavy-duty, mission-critical drive applications include coal conveyor systems, coal crushers, boiler feed pumps, and turbine generators that all operate at speeds different from the drivers. The reliability of …
It is either motor or turbine driven. It consumes about 2 to 2.5% of the power output. 2.1.1. Working Principle. In the case of coal-fired boiler, the coal is supplied from the coal storage to the boiler through the coal handling plant.

In the case of emergency the coal is fetch from coal yard. Coal feeder control the quantity of coal from
A steam power plant continuously converts the energy stored in fossil fuels i.e. coal, oil, etc. or fossil fuels e.g. uranium, thorium into shaft work and ultimately into electricity. The working fluid is "water" which is sometimes in the liquid phase and sometimes in the vapor phase during its cycle of operations.

advanced coal-fired power plants, where there is a growing emphasis on achieving high unit efficiencies. Combining coal drying with capture of CO2 would provide additional opportunities for efficiency improvements. This could be done with either a pulverized coal-fired boiler with a post-combustion CO2 scrubber, an oxy-fuel fired boiler or a coal
In this system, coal from the coal yard is crushed to the required size in coal crusher. The crushed coal is supplied to the coal bunker in the boiler house. This coal is fed to the furnace through coal hoppers where it is burnt. The products of combustion, namely ash and un-burnt coal, are disposed to the ash storage site. 2.
