Feasibility Study of Oxy-fuel Combustion Retrofit for Operational CFB Boilers
摘要
Abstract
Oxy-fuel combustion in circulating fluidized bed(CFB)boilers,as an effective large-scale carbon abatement technology,is increasingly valuable due to the reduced cost of oxygen acquisition via water electroly-sis,which consumes surplus renewable energy.Based on a well-established one-dimensional CFB boiler calcu-lation model,the operations of 135 MW and 350 MW CFB boilers under oxy-fuel combustion conditions are simulated.The temperature distribution and heat transfer characteristics of the furnace and back pass are ana-lyzed.The results show that replacing the air combustion atmosphere with pure oxygen and adjusting the oxy-gen volume concentration to approximately 30%through flue gas recirculation can achieve a temperature distri-bution similar to that of air combustion,while maintaining the structural integrity of the boiler.Furthermore,this retrofit enables efficient combustion and stable heat transfer.The findings provide valuable insights for ret-rofitting operational CFB boilers with oxy-fuel combustion technology and lay a solid foundation for its engineer-ing application in carbon capture.关键词
