Atmospheres near the boiler wall, including oxidizing and reducing atmospheres. The coking in the reducing atmosphere will be intensified, because the reducing atmosphere will reduce the melting temperature of the ash by about 200. Once the local coking of the boiler is not effectively controlled, it will quickly spread to a large area around, when the coke reaches a certain thickness and the temperature field in the furnace changes, the phenomenon of coking will occur, and if the coking area is large, it will destroy the power field in the furnace and extinguish the fire, thus affecting the normal production order.
Boiler anti-coking is very important. So how do you prevent the boiler from coking? The problem can be solved by surface treatment technology, and the method of preparing coating for the boiler wall with KNM1000 boiler anti-coking energy-saving coating can be used to solve the problem.
Specifically, first of all, the surface of the boiler wall is cleaned to improve the adhesion of the coating to the substrate. Secondly, the KNM1000 boiler anti-coking energy-saving coating is applied to the boiler wall, and after curing, a layer of high-temperature, impact-resistant, friction-resistant, anti-oxidation, and anti-bonding coating can be formed on the surface of the desulfurization wall, so that the surface performance of the boiler wall can be improved, and the anti-coking ability of the boiler can be enhanced, so as to ensure safe production.
