常压炉耐火纤维喷涂衬里

Fire-proof Fabric Spray Lining for Atmospheric Furnace

哈尔滨石化分公司一立式加热炉原辐射室及对流室采用耐火砖及耐火纤毯衬里 ,热量损失严重 ,炉体变形。后在原衬里上加喷了一层 5 0mm厚的耐火纤维涂层 ,从而使辐射室和炉顶温度分别下降了 4 6℃和5 6℃。喷涂衬里适用于旧炉衬改造 ,可简化设计和施工。与原检修方案相比 ,可节约资金

One of the vertical furnaces in Harbin Petrochemical Company suffered from great heat losses and body deformation when the firebricks and fire-proof fiber sheets were applied for the radiant and convection sections. The application of a 50 mm fire-proof fabric spray coating on the original lining reduced the temperature of the radiant section and top of the furnace by 46℃ and 56℃ respectively. This spray lining, simple in engineering and construction, was specially applicable for the revamp of the existing furnace. Over 350,000 yuan (RMB) was saved as compared with the original maintenance option.
