Question
A coal-fired 930-MW power plant is operating under the following
conditions:
Coal carbon content C = 80%, coal ash content A = 6%, and heating
value LHV = 30 MJ/kg
Cooling water temperature difference Δtcw = 10.5 K
Plant electrical efficiency ηel is 0.43 and capacity factor CF is 0.82.
Boiler efficiency ηb = 0.92
ESP efficiency ηESP = 99%
Calculate (d) the condenser heat rejection rate and cooling water rate, (e) the annual yield of ash, and (f) the annual emissions of particulates.
