一、锅炉的基本概况抚顺钢厂二炼分厂的一台12吨/时全自动燃油锅炉,是西德比利劳斯公司的产品,于1979年10月制造,抚顺钢厂于1980年12月份安装投产使用。该炉是为VOD/VHD炼钢精炼炉配套用的生产锅炉。锅炉结构型式类似我国的卧式内燃水背式回火管锅炉。锅筒外径3 m,板厚22mm,长5.5m,材质17Mn4,波型炉胆外径1.3m,板厚14mm,材质17 Mn 4,锅炉后部内烟室的上板和下板厚30mm,背板厚22mm,材质H_Ⅱ,内烟室均采用角焊连接。锅炉的设计压力为18kgf/cm~2,正常运行工作压力为16kgf/cm~2,过热蒸汽温度221℃。该炉最大的特点
First, the basic profile of the boiler Fushun Second Steel Plant, a refinery 12 tons / hour fully automatic oil-fired boiler, the West German Billie Laws company’s products, manufactured in October 1979, Fushun Steel in December 1980 Installation and put into production use. The furnace is a production boiler for VOD / VHD steelmaking refining furnace. Boiler structure similar to China’s horizontal internal combustion water back-fire tube boiler. Drum diameter of 3 m, thickness 22mm, length 5.5m, material 17Mn4, wave-type furnace gallbladder diameter 1.3m, thickness 14mm, material 17 Mn 4, the boiler rear smoke chamber on the plate and the lower plate thickness 30mm, Back thickness 22mm, material H_ Ⅱ, smoke chamber are used fillet welding connection. Boiler design pressure of 18kgf / cm ~ 2, the normal operating pressure of 16kgf / cm ~ 2, superheated steam temperature of 221 ℃. The biggest feature of the stove
