Energy Consumption Analysis of Coal-Fired Power Plant with CO₂ Capture System Based on Solar Energy

Abstract:

To the question of high energy consumption and cost about coal-fired power plant CO₂ emission,this paper from the coupling mechanism research of solar energy collection system,amidogen CO₂ emission reduction system and coal-fired power plant thermal system ,as well as systematic integration and optimization ,and then based on equivalent heat drop method ,It analyses the thermal economy changes about this new type integration system at THA, 75% THA, 50% THA conditions corresponding to the different carbon capture rate of the four programs .Finally,it works out the unit thermal economy variation tendency at different rate of carbon capture,its thermal economy relative degree increase if capture rate increase .On this basis ,this paper optimizes the integration system in order to achieve low power consumption, low cost of CO2 emissions for reference.
