Carbon Emission Calculation and Analysis of Carbon Emission Reduction Technology of Coal-Fired Generator Set
Based on the features of coal-fired generator set,according to the CO2 generation mechanism,a calculation method was given for the carbon emission intensity of coal-fired generator set.Based on the test data of 46 sets,a study was conducted using the calculation model established to investigate the influence of unit level,coal quality and unit load change on the carbon emission intensity.Meantime,the measure to reduce average power supply carbon emission intensity was proposed.Results show that the carbon emission intensity is mainly affected by the coal consumption rate of the power generation unit,the received base low calorific value of coal combustion,and the received base carbon content of coal combus-tion.The estimation formula was fitted between carbon emission intensity and coal consump-tion rate for power generation,and the CO2 generation coefficient per unit standard coal con-sumption for soft coal is 2.79 t/t.The average power supply carbon emission intensity in Anhui Province of 2021 fell to 658 g/(kW·h).It was found that increasing the proportion of new energy installed capacity and electricity,improving the efficiency of coal-fired sets,coal-fired coupled biomass power generation and carbon capture,storage and utilization technolo-gy,low carbon dispatch and other measures can significantly reduce the carbon emission in-tensity of regional electricity.
