Postcombustion CO 2 capture is primarily applicable to conventional natural gas and pulverized coalfired (PC) power generation. In a typical PC power plant, fuel is burned with air in a boiler to produce steam, which drives a turbine to generate electricity. The boiler exhaust, or flue gas, consists mostly of nitrogen (N2), and CO2.
