Boiler spray protection scheme

       

What are the protection schemes for boiler spraying, and wococarbide.com will explain to you below. Scope of protection: Design different spraying schemes according to the quality of boiler coal, content of harmful components, working conditions, etc., requirements for the location, area, and thickness of anti-wear and anti-corrosion spraying, and the actual survey after the boiler is shut down. a design.

2. Working wire spraying:

Furnace type	spray material	thickness	hardness	Bond strength
circulating fluidized bed boiler	LX88A、SAM、KM99	0.6mm--0.8mm	≥HRC60	≥55MPa
pulverized coal furnace	PS45、45CT、SOR	0.3mm--0.4mm	≥HRC40	≥55MPA

3. Spray sealing agent and brush sealing agent to reduce the porosity of the coating and prevent the erosion of harmful media. The surface of the coating is sealed with a high-temperature special sealing agent.

The composite metal spray coating thus prepared can be used for protection and can meet the protection requirements of the boiler against corrosion and abrasion.
