Because the chimney anti-corrosion materials are various, the quality is uneven, imported anti-corrosion materials and titanium plate is expensive, the construction cycle is long, the construction quality control is difficult, it is inevitable that the construction defects, resulting in the chimney operation for a period of time after the leakage phenomenon, selected paint chimney paint is imperative.  

For those who do not use desulfurizing chimney paint for anticorrosion, the light ones will have local corrosion, and the corrosion rate, the number of leakage points and the area will increase year by year. For the heavy ones, the structural strength of the chimney barrel will decrease, the concrete strength will be seriously damaged, the steel inner barrel will be corroded and perforated in a large area, the load-bearing strength will be reduced, and even collapse.  Chimney local corrosion repair can only solve the problem of local, other repair parts corrosion leakage hidden trouble, still exist to thoroughly solve the problem of the chimney corrosion, it is considered that the new type of desulphurizing chimney coating is one of the effective ways to thoroughly solve the chimney corrosion, the original GGH operation situation of desulfurization system to safeguard GGH, cut can not be as GGH running failure more easily to remove it.  For the desulfurization system without GGH, it is necessary to consider new heat source to increase the exhaust temperature after desulfurization, and ensure that the exhaust temperature of the chimney is above the dew point. Only in this way, the corrosion problem of the chimney can be greatly reduced, the time interval of the chimney anticorrosion can be extended, and the safe operation of the chimney can be ensured.
