I was given this problem as an excercise in thermodynamics and to better understand powerplant systems. I am having difficulties because as a civil engineering student I haven't taken alot of thermodynamics. The one course I did take was several semesters ago and wasn't that advanced. 1. The problem statement, all variables and given/known data We are building a 600 MegaWatt (gross) peaking unit coal plant. The plant burns weatern coal assumed to have 8200 BTU/lb Turbine Conditions Turbine has High pressure, Intermediate Pressure and 2 Double Flow low pressure turbines. Main Steam at 2400 psig, 1000 degress F Reheat Steam at 1050 degrees F Exhaust Condenser at 2.0 in Hga No extractions for feedwater heaters Boiler Data Western coal is assumed to have 5% ash 50 psig drop through the reheater 75 psig drop through the econmmizer, waterwalls, drum, and superheater. Stoichiometry in combustion zone is 0.97 Furnace exit gas temp is 600 F Boiler Losses, in % of full load 4.4% dry flue gas 3.3% as fired fuel moisture 4.4% H2 moisture 0.7% Unburned carbon 0.2% radiation and convection 0.1% moisture in air 0.5% unaccounted for losses Turbine Data HP exhaust pressure of 600 psig HP effeciency of 0.88 IP/LP efficiency of 0.88 Use motor driven boiler feed pump Do not consider the following: Bearing and generator mechanical losses Shaft seal leakages Radiation and convective turbine losses Station power loads Atemperating sprays The unit can reach full load with 5 coal mills. Design the neccesary coal feeders (Tons/Hr) to supply these mills to sustain the powerplant. 3. The attempt at a solution I am not looking for someone to solve this for me, I am just trying to figure out where to get sarted. All the infromation is overwhelming. Can someone tell me where in the system I am supposed to start and maybe point to where online I can see good examples of Rankine cycle problems being worked?
