针对平煤集团发电厂引进的俄罗斯产 2 3 0t/h锅炉保温及密封中存在的环境标准不同、材料购买困难和施工难度大等问题进行了分析与研究 ,更改了俄方的设计 ,选用国产保温密封材料和相应施工方案 ,节省了投资 ,加快了施工进度。运行结果表明 ,改进后锅炉保温及密封性能良好。 In view of the different environmental standards in the 230 t / h Russian-made thermal insulation and sealing of the Russian-made power plant imported from the Pingmei Group Power Plant, the problems of material purchase difficulty and construction difficulty are analyzed and researched, the Russian design is changed, the domestic Insulation sealing materials and the corresponding construction program, saving investment and speeding up the construction progress. Operation results show that the improved boiler insulation and sealing performance is good.
