加压富氧流化床燃烧传热特性研究进展
Research progress on heat transfer characteristics of pressurized oxy-fuel fluidized bed combustion
摘要
Abstract
Oxy-fuel combustion technology,as an efficient CO2 capture method,demonstrates significant environ-mental and economic advantages in coal-fired power plants.Building upon this,pressurized oxy-fuel fluidized bed combustion technology,which integrates oxy-fuel combustion with pressurized circulating fluidized bed technology,further broadens fuel adaptability while markedly enhancing combustion efficiency and CO2 enrichment,showcasing promising industrial application prospects.This paper systematically reviews research progress on heat transfer charac-teristics between heating surfaces and the bed layer in pressurized oxy-fuel fluidized bed furnaces,with a focused a-nalysis of the heat transfer mechanisms in gas-solid two-phase flows and their key influencing factors.The study re-veals that increased system pressure significantly intensifies heat transfer in the dense-phase zone,whereas radiation-dominated heat transfer becomes predominant in the dilute-phase zone under high-temperature conditions.Additional-ly,the regulatory effects of particle size distribution and fluidizing medium on heat transfer characteristics cannot be overlooked.Finally,future research directions in this field are further outlined.关键词
