Problems solved by technology
[0005] The invention solves the problem that the corrosion rate of the local heating surface of the water cooling wall is too high due to the presence of corrosive gas, ash deposits, flue gas erosion, etc. To solve the problems such as fast, a protective layer structure for preventing local corrosion of the flue of the waste incineration boiler is provided, which effectively protects the waste incineration boiler. Scrubbing of the pipe wall to avoid local corrosion acceleration

The invention discloses a protective layer structure of a waste incineration boiler and capable of preventing flues from local corrosion. The protective layer structure comprises a first-flue front wall, a first-flue rear wall, a second-flue front wall and a second-flue rear wall; the first-flue front wall and the first-flue rear wall are arranged vertically and form a first flue; the second-flue front wall and the second-flue rear wall are arranged vertically and form a second flue; the first flue is communicated with the upper portion of the second flue, a ceiling is arranged to connect the first-flue front wall with the second-flue rear wall, and the top end of the first-flue rear wall is connected with the top end of the second-flue front wall; a first protective layer is arranged at the position, close to the ceiling, of the upper portion of the first-flue front wall, the front portion of the ceiling is provided with a second protective layer, the rear portion of the ceiling is provided with a third protective layer, and the upper portion of the second-flue front wall is provided with a fourth protective layer. Probability of contact reaction between corrosive gas and pipe walls is lowered through blocking of the local-corrosion protective layers, so that speed of corrosion thinning is decreased.
Description
technical field [0001] The invention relates to an anti-corrosion layer structure, in particular to an anti-corrosion layer structure for preventing local corrosion of a flue of a garbage incineration boiler. Background technique [0002] The composition of municipal solid waste is complex and changeable, including kitchen waste, wood and bamboo, textile, paper, rubber and plastic, and non-combustible. The non-combustible category includes metal, glass, brick and tile, etc. Garbage is a randomly mixed fuel, and its moisture content varies greatly with the seasons, resulting in large changes in its calorific value. In addition, with the improvement of people's living standards, the calorific value of garbage is also rising. If the waste sorting and recycling are carried out well, the calorific value of urban domestic waste will be further improved in the future. [0003] Since municipal solid waste incineration power generation can achieve significant capacity reduction, la...
