摘　　要：介绍了蓄热式加热炉燃烧技术工作原理和发展,并对主要加热设备如蓄热烧嘴、蓄热室、换向装置、控制系统进行了分析。蓄热式技术能够最大限度地回收出炉烟气的热量,大幅度地节约燃料、降低成本,同时还能提高炉子的产量,并减少CO2和NOx的排放量;在国际上被称为21世纪的关键技术之一。石家庄钢铁公司加热炉采用PLC对蓄热器的换向装置进行自动控制,每150s换向一次。新型蓄热室分别预热空气和煤气,可以使空气和煤气温度均达到800℃以上,热效率达70%以上,大大节约了燃烧费用。This paper introduces the working principle and progress of regenerative reheating furnace combustion technology and analyzes main heating equipment such as regenerative burner nozzle,regenerator,reversing arrangement and control systemWhen using the regenerative reheating technology,a great deal of heat can be recovered from flue gas,with a great save of fuel and cost,increase of furnace output and reduction of CO2 and NOx dischargesThis technology is one of key technologies in the twentyone centuryIn Shijiazhuang Iron & Steel Co,the PLC is used for autocontrol of regenerator's reversing arrangement on reheating furnace,with reverse run per 150 minutesNew regenerator can warm up the air or coal gas to a temperature of over 800℃,with a thermal efficiency of over 70% and a great save of fuel cost
