What are the advantages and disadvantages of boiler spraying

       Boiler spraying, thermal spraying, supersonic arc spraying, boiler heating surface anti-wear and anti-corrosion, boiler water wall anti-wear spray, deflector anti-wear, anti-wear plate installation, longitude and latitude anti-wear, grille anti-wear, CFB boiler anti-wear technology

High-pressure boiler spraying (air-cooled power spraying) is noisy and requires a minimum pressure of 15 atmospheres, resulting in a huge equipment that cannot be moved. In addition, some equipment needs to be operated under helium, nitrogen or inert gas, because the noise exceeds 100 decibels, high pressure requirements and practical use of dangerous gases, resulting in high safety and low cost. Moreover, the air consumption and powder consumption are large, and the spraying orientation is poor. The high-pressure boiler spraying equipment has a very complicated arch powder device. It uses a vacuum-filled arch powder bucket, and the cost of the powder bucket alone is 150,000 yuan. Moreover, because the high-pressure equipment has no technological foundation, the sprayed coating is uneven and prone to trachoma.

Compared with the low requirement of 15 atmospheres of high pressure, the working pressure of low pressure cold (cold air power) spraying equipment is only below 5-8 atmospheres. It has no working condition requirements, and the noise is less than 60 decibels. It has no high temperature, no flame, no dangerous gas, no radiation and chemical waste, can be operated by hand, high safety, and good orientation. The spraying area can be smaller than that of high-pressure boiler spraying without using a mold, that is, its operability is better.
