ANALYSIS OF POWER GENERATION PROCESS EXERGY EFFICIENCY OF LARGE CDQ WASTE HEAT BOILER UNDER THE BACKGROUND OF DOUBLE CARBON
This paper analyzes the power generation technology of coke dry quenching (CDQ) waste heat boiler, and compares the exergy efficiency of medium temperature medium pressure boiler and high temperature high pressure boiler. The scheme of high temperature ultrahigh pressure primary intermediate reheat boiler to further improve the power generation efficiency of CDQ waste heat is put forward, and the exergy efficiency is analyzed. The bottleneck problem of further improving power generation efficiency by CDQ waste heat power generation and the exergy efficiency limit under the current process conditions are obtained.
