Product Description

INTRODUCTION OF THE SULFURIC ACID WASTE HEAT RECOVERY BOILER

the waste heat recovery boiler shall be used in sulfuric acid preparation system of 20-500kt/a, after roasting of sulfur ore, coming into being the flue gas with high concentration of so2 and dust of 300-400g/Nm3 and high temperature of 800-11,000 degree celsius, flue gas transfers heat in sulfuric acid waste heat recovery boiler for producing steam for production and power generation, and the dust also shall be cleaned. about 380 degree celsius low temperature, low dust, rich so2 flue gas enters into sulfuric acid downstream process.
