Heat recovery boiler for Sulfuric Acid Plant is an important technics device in the system of producing Sulfuric Acid as well as a set of waste heat recovery device. It can cool the high temperature furnace gas generated from the iron pyrite ore fluidized calcining kiln to meet the required temperature by sulfuric acid producing technics, at the same time, the overheated steam generated by residual heat from recycled gas could be used for GT power generator or other industries. HBG initiatively focused on the usage of the waste heat from the sulfuric acid producing by iron pyrite ore in the beginning of 70’s, up till now, HBG has manufactured a series of HRSGs for sulfuric acid plant with the capacity of 40000-400000 ton/year, among which 200 units are operating around China right now.

The sulfuric acid plant heat recovery boiler located in Wengfu, Guizhou, China is cooperative developed by HBG and Kawasaki with the largest capacity of 400000ton/year among all the sulfuric acid plants in China so far, and it reached the international advanced level.

The sulfuric acid plant heat recovery boiler installed in HUANGMAILING INDUSTRIAL in HUBEI of China with the capacity of 280000 ton/year is the second largest one in China, with basic design from ALSTOM Finland and detail design and manufacture from HBG.
