According to different procedures of different acid making approaches, Sulfuric acid waste incineration developed by this company and applied in recycling of sulfuric acid waste heat and power generation project include sulfuric acid-making waste heat boiler and pyrite acid-making waste heat boiler. The structures of sulfuric acid waste incineration boiler include fire tube and water tube types. The main circulation modes of water in boiler are natural circulation and forced circulation. According to the fact that the flue gas of sulfuric acid making is characterized by sealing property, compact conformation, and convenient installation, In light with the fact that the flue gas of pyrite acid making is characterized by low side negative pressure and high dust content, pyrite acid making mainly adopts water tube type, which has the features of abrasion resistance, soot deposit resistance, and good low-temperature dew point corrosion. The operation of this series of sulfuric acid waste incineration boiler is reliable and safe. Sulfuric acid waste incineration is well received by users, thus ideal equipment of energy saving for enterprises.
