A coal power plant has a heat rate of 9700 Btu/kWh using coal which has an energy content of 24,000 kJ/kg. Burning coal results in about 60% carbon (released as CO2 or CO), 2% sulfur (released as SO2 and if not captured results in sulfuric acid), and ash at 8% (70% of it is fly ash). Find the following a) The carbon emission rate in (g/kWh) b) The sulfur emission rate in (g/kWh) c) The fly ash emission rate in (g/kWh) d) If an advanced coal plant is constructed instead with a heat rate of 8800 Btu/kWh, would this increase or decrease the carbon emissions. Problem 2: 20 points Use the table¹ below and an FCR = 16% to determine the COE from the following plants: a) A Steam-Injected Gas Turbine (STIG) plant at CF = 0.55, plant life = 50 yrs. b) New hydro plant at CF = 0.75, plant life = 80 years. c) Wind turbine with CC = $750/kW, CF = 0.4, 0&M = 0.6 ¢/kWh, plant life = 25 years. d) Write the RR for the STIG plant in part (a) as a function of EOH and as a function of CF.
