Generation methods considered include: fossil fuels (coal, oil, oil shale, natural gas), biogas, biomass, bio-voltaic, geothermal, hot dry rock, hydro and micro-hydro, nuclear, solar thermal, solar photovoltaic, and wind.
Components of Coal Fired Thermal Power Station: Coal Preparation; i) Fuel preparation system: In coal-fired power stations, the raw feed coal from the coal storage area is first crushed into small pieces and then conveyed to the coal feed hoppers at the boilers.
Pulverised coal power plant: Coal plant performance specifications: The coal plant configuration is based on Case 9 of the "Cost and Performance Baseline for Fossil Energy Plants" report (DOE/NETL, 2013) The steam generator consists of a water wall furnace, a platen secondary superheater and a final superheater in the upper region of the furnace and a primary superheater, reheater, and ...
