开封火电厂1号炉系四川东方锅炉厂生产的DG220/100-2型高温高压煤粉炉,1972年5月安装,1973年4月正式投产。原配50MW汽轮发电机组,因汽机经常发生断叶片等事故,改降出力至40MW运行。由于设备本身存在缺陷,燃烧不稳,常常灭火,仅1989年就灭火19次。为了改善燃烧,提高锅炉运行的安全性、经济性,增强运行人员调整手段,在2号炉燃烧器改造的基础上,决定将1号炉燃烧器改为不对称式夹心风燃烧器。经燃烧调试及10个多月的运行证明,锅炉燃烧稳定,调整便利,大大减少了锅炉灭火次数。
Kaifeng Thermal Power Plant No. 1 furnace produced by Sichuan Dongfang Boiler Factory DG220 / 100-2 high temperature and pressure pulverized coal furnace, installed in May 1972, April 1973 formally put into operation. The original 50MW turbine generator set, due to frequent turbine blades and other accidents occurred, down to 40MW output. Due to flaws in the equipment itself, unsteady combustion, fire is often extinguished, and fire was extinguished only 19 times in 1989. In order to improve the combustion, improve the safety and economy of boiler operation and enhance the adjustment method of operation personnel, on the basis of the reformation of No.2 burner, it was decided to change No1 burner to asymmetrical type of Sandwich burner. After commissioning and more than 10 months of combustion commissioning proved that the boiler combustion stability, convenient adjustment, greatly reducing the number of boiler fire.
