淮北电厂~#4炉系上海锅炉厂制造的SG-400/140M410型超高压中间再热煤粉锅炉,为“Π”形布置,无中间水平烟道,在竖井尾部由上而下布置二级再热器和二级省煤器。烟气离开炉膛后急剧转向,使尾部烟道的后部灰分密集,造成低温再热器,后墙包墙管和省煤器严重磨损,1978年7月投产后尾部爆管频繁,安全生产受到威胁。1982年
Huaibei Power Plant ~ # 4 furnace Shanghai Boiler Factory manufacturing SG-400 / 140M410-type high pressure reheat pulverized coal boiler is “Π” -shaped arrangement, there is no intermediate horizontal flue, the tail shaft from top to bottom layout of two Reheater and secondary economizer. After the flue gas leaves the furnace and turns sharply, the ash in the rear of the tail flue is intensively concentrated, which causes severe wear of the low temperature reheater, the rear wall wall pipe and the economizer. The tail squirting is frequent after the start of operation in July 1978, and safety production is affected Threats. 1982
