1. Product Characteristics

Industrial boilers preheat combustion air with recycled gas to reuse the waste heat. Recycled gas loses thermal energy as it passes through the heat transmitter. During this process, sulfuric acid dew is formed, which means that the acid dew point is reached. Sulfuric acid dew corrodes industrial boiler, reducing its lifespan. To improve the anti-corrosion performance against sulfuric acid, Cr, Ni, Co and other chemical elements are added.
