<p>PURPOSE:To prevent the corrosion of a louver provided at the discharge port of hot air from being corroded by SOx within a waste gas by applying a paint consisting of at least a phosphate series compound, a complex oxide and a catalytic substance to a part with which a combustion waste gas makes contact. CONSTITUTION:A burning finshed paint C consisting of a phosphate capable of obtaining a coating layer having an excellent water resistance, excellent in adhesion and surface hardness, singly or using a promoter together, a metal oxide purifying them and uncreasing contamination resistance when CO, NOx, S, and the like adhere to the surface of the lower A, and a catalyst consisting of a complex oxide using zinc thermally stabilized. Accordingly, the exhaust flue of the combustion apparatus becomes excellent in contamination resistance and weather resistance, and, in addition, purification of waste gas can be performed by the catalyst.</p> |
