Model Construction and Carbon Emission Reduction Analysis of Direct Coupling of Biomass in Coal-Fired Unit
摘要
Abstract
Direct coupling of biomass in coal-fired power plants can significantly reduce carbon dioxide emissions,which is one of the most important paths for coal-fired power plants to achieve the"carbon peaking and carbon neutrality"goal.In this paper,a 300 MW pulverized coal boiler model built by Aspen Plus is used to simulate the direct coupling of biomass in coal-fired power plants.According to the simulation results and the established economic and carbon emission reduction model,the electricity cost and carbon emission changes of coal-fired unit mixed with biomass are analyzed.The results show that with the increase of biomass blending ratio,the additional cost per kWh of coal-fired plant will gradually increase,but after considering the carbon tax factor,the additional cost per kWh will decrease.Therefore,setting a reasonable carbon tax price can effectively promote biomass blending and utilization,and the economic cost of biomass blending can be reduced by adjusting carbon tax.The coupling of coal-fired units with biomass can significantly reduce CO2 emissions,and the key is to reduce the water content of biomass.The research results provide a reference and support for the technical implementation and economic evaluation of direct coupling of biomass in coal-fired power plants.关键词
