锅炉是一种经常处在高温高压下工作的热力设备,热水锅炉的承压部分在循环泵造成的压力下工作,其内部受到水中有害物质的冲刷和腐蚀,外部又经常受到烟气的侵袭,烟气中的有害成分对其产生腐蚀及磨损,因而极容易出现受热面管路及锅筒等钢材的变形、裂纹、鼓包与损坏。因此,现主要对锅炉本体的检验与维修进行分析。 The boiler is a kind of thermal equipment that often works under high temperature and pressure. The pressure part of the hot water boiler works under the pressure caused by the circulating pump. The interior is washed and eroded by the harmful substances in the water, and the external is often affected by flue gas , The harmful components in the flue gas corrode and wear it, so it is very easy to appear the heating pipe and drum steel pipe deformation, cracks, bulging and damage. Therefore, the main boiler body inspection and maintenance analysis.
