Consider a power plant of 400 mw e burning coal with a hhv of 30,200 kj/kg and sulfurcontent of 2% by mass. assume the power plant efficiency of 40% and heat capacity ofwater is 4.18 kj/kgk. a) determine the rate of fuel (coal) consumption in kg/s. b) limestone (caco3) is used to capture so2. the chemical reaction is given below. determinethe amount of limestone (caco 3 ) required per hr. caco3 + so2 + 0.5o2 → caso4 + co2
