Study on CO2 Emission Reduction from Chinese Coal-Fired Power Plants Between 1993 and 2010

Based on the Chinese thermal coal and power generation data,such as ultimate analysis,proximate analysis,low heat value (LHV) on as received basis,power generation volume,thermal coal consumption volume and net coal consumption rate,several mathematical models for calculating CO2 reduction by Chinese coal-fired power plants are established.Calculations of the CO2 emission factor (CEF),the CO2 emission volume and reduction volume are made according to these models.The calculation results reveal that between 1993 and 2010,the CO2 emission volume reached 31.069 Gt,reduced by 0.439 Gt,averaging 28.83 Mt each year.
