一、我市十台蒸汽锅炉设备损坏的基本情况。1.某煤矿购进一台SHF20-25/400型蒸汽锅炉、设备进矿后,没有按规定堆放,数月后,才架设一座临时工棚、将近三年,无人过问。安装前,发现有些炉管有点状腐蚀.未作认真处理、就进行组装,组装结束后,在工作压力下进行水压试验时,发现有两根对流管在点腐蚀处漏水。一年后,准备点火烘炉,上水时,又发现炉膛前墙左起第15根水冷壁管卫燃带以上200毫米处泄漏。 First, the city’s ten steam boiler equipment damage the basic situation. 1. A coal mine purchased a SHF20-25 / 400 steam boiler. After the equipment was put into the mine, it was not stacked as required. Only a few months later, a temporary shed was erected. For almost three years, no one was asked about it. Before installation, it was found that some furnace tubes were slightly corroded, and the assembly was completed without any serious treatment. After the assembly was completed, two convection tubes were found to leak water at the point corrosion at the hydraulic pressure test under working pressure. One year later, when it was time to prepare an ignition oven and go to Sheung Shui, it was found that the 15th water-cooled wall pipe at the left of the front wall of the furnace leaked at a distance of 200 mm.
