Impact of Coal Calorific Value on Unit Operation and Consumption of Power Station Coal and Corresponding Measures
Coal quality is the key factor affecting power plant energy conservation and environmental protection level,also affects the consumption of power station coal.The influence mechanism of coal quality on boiler efficiency and power station coal consumption was analyzed from the change of coal calorific value,ash content,moisture content,sulfur content and nitrogen content.Based on the calorific value,power generation and power station coal consumption data of Jiangsu Province in the past two years,the influence of the change of coal calorific value on the consumption of power station coal in the province was quantitatively analyzed.According to the estimation of the coal-power generation in Jiangsu Province in 2022,the annual average calorific value of power station coal in the province increased by 418.4 kJ/kg,and the total annual thermal coal consumption decreased by about 3.9×106 t,accompanied by a reduction of approximately 1.0×107 t of CO2 emissions.Therefore,from the aspects of strengthening source control,rational storage and blending,accelerating renewal and transformation,fine operation management and optimization of coal storage structure,relevant measures were proposed to control the calorie-value ofpower station coal,so as to reduce the coal consumption of power generation,control pollutant emissions,and play a role in energy conservation and emission reduction.
