How to do the comprehensive repair work of the steam boiler?

First of all, when the steam boiler is undergoing a comprehensive repair and inspection, it is first necessary to clear the water ditches and sludge in the steam boiler, and then use clean water to wash these water ditches and sludge clean.
Then there will be a lot of soot and ash on the fired part of the boiler. Such substances should also be eradicated during the overhaul.
Finally, because the steam boiler is made of metal processing and has to touch a lot of water or steam, it is inevitable that corrosion will occur. When the boiler is overhauled, the corrosion of the boiler should be repaired. Reliability is one of the characteristics of gas-fired steam boilers. Through strict selection of raw materials, combined with domestic and foreign manufacturing methods, the service life of the boiler can be increased. Safety, compared with old boilers, the safety functions are greatly improved, and the functions such as explosion-proof and fire-proof are all achieved to the extreme.
