Description
技术领域 technical field

背景技术 Background technique
余热锅炉，顾名思义是指利用各种工业过程中的废气、废料或废液中的余热及其可燃物质燃烧后产生的热量把水加热到一定工质的锅炉。具有烟箱、烟道余热回收利用的燃油锅炉、燃气锅炉、燃煤锅炉也称为余热锅炉，余热锅炉通过余热回收可以生产热水或蒸汽来供给其它工段使用。 Waste heat boiler, as the name implies, refers to a boiler that uses waste heat in waste gas, waste or waste liquid in various industrial processes and the heat generated by the combustion of combustible substances to heat water to a certain working medium. Oil-fired boilers, gas-fired boilers, and coal-fired boilers with smoke boxes and flue waste heat recovery are also called waste heat boilers. Waste heat boilers can produce hot water or steam for use in other sections through waste heat recovery.
余热锅炉在长期使用过程中，锅炉壳体裸露部分尤其是烟气挡板门常常会因为烟气中的硫化物与水汽作用产生液态硫酸而被腐蚀。烟气挡板门在被腐蚀后，其密封性能就无法得到保证，导致烟气外漏。目前，对于这种情况常用的对策是，一旦发现烟气挡板门壳体出现因壳体腐蚀而产生烟气外漏的现象，立即停机，对烟气挡板门进行更换作业，或者对烟气挡板门进行焊接维修等。由于烟气挡板门重量、体积均较大，不便于移动，在维修作业过程中，存在较大困难。 During the long-term use of the waste heat boiler, the exposed part of the boiler shell, especially the flue gas baffle door, is often corroded due to the action of sulfide in the flue gas and water vapor to produce liquid sulfuric acid. After the flue gas baffle door is corroded, its sealing performance cannot be guaranteed, resulting in the leakage of flue gas. At present, the commonly used countermeasures for this situation are, once the flue gas baffle door casing is found to have flue gas leakage due to casing corrosion, stop the machine immediately, replace the flue gas baffle door, or replace the flue gas baffle door. Gas damper door for welding repairs, etc. Due to the large weight and volume of the smoke baffle door, it is not easy to move, and there are great difficulties in the maintenance operation process.
