Technical Field

Background

With the urban production level and the abundance of industrial materials, the components of the pre-incinerated garbage become more complex, wherein the solid waste comprises kitchen wastes, waste plastics, waste metals, waste electrical appliances and furniture and the like, the organic content is high, carbon, hydrogen and oxygen are main components of the waste, but a large amount of harmful elements such as chlorine, alkali metals and the like are also contained, the components can generate HCl gas and deposition salts such as NaCl, KCl and the like after high-temperature incineration, so that the metal heating surfaces such as water-cooled walls, superheater tubes and the like are seriously corroded, and the existence of sulfur element is also related to high-temperature corrosion. The popularization and development of the waste incineration technology are severely limited by the high-temperature corrosion of the heating surface of the boiler, so that the corrosion prevention requirement of the heating surface of the boiler of the waste power plant is huge.

At present, the heating surface of the domestic garbage power plant boiler has two solutions: firstly, the carbon steel pipe is adopted and freely corroded, so that the cost is cheap for the first time, but the carbon steel pipe needs to be replaced every year, the replacement work is complicated, time and labor are consumed, the comprehensive cost is huge, and the scheme is gradually cancelled in the existing power plants with economic conditions; secondly, a scheme of overlaying a 625 nickel-based alloy is adopted, an anti-corrosion layer is overlaid on a heating surface of a boiler, the scheme is mature, the market degree is high, but the defect that the scheme cannot be changed exists, the 625 alloy cost is particularly high, the net cost per square is nearly 1 ten thousand yuan, each furnace is about 2500 square, other equipment is not contained, the manufacturing cost of a light-water cooling wall is about 3000 ten thousand, a general power plant cannot bear the 625 alloy, the 625 alloy has a bottleneck restricting the industry development, namely, the 625 alloy is only used for low-temperature parameters, and the corrosion resistance of the 625 alloy is exponentially reduced when the temperature of the heating surface reaches 415 ℃.

The micro-fusion welding solves the problems of two major pain points in the industry, namely the corrosion resistance under the cost and high parameters. The film wall is heated in the early spraying process, a local tube bank forming the whole film wall is flat and long, and one surface of the tube bank is easily deformed after being heated. The bank of tubes adopts the flat jet mode to carry out hot spraying usually, and incomplete powder easily falls into the slot when the bank of tubes flat jet, is difficult to the clearance, increases artifical burden, improves the processing cost. The floor area is large when the tube bank is placed in a spraying way, and the utilization rate of the limited space of a factory is reduced. The process needs to spray an anti-corrosion alloy, generally nickel-based alloy powder, on a heated surface in the early stage, and as is well known, a thermal spraying coating is porous under a microscope, and the compactness of the coating and the bonding strength of the coating and a substrate interface are difficult to guarantee by one-time spraying.
