Shaoguan Qujiang Shunfu — Brick-Kiln Flue Gas Treatment — Case Study
Published 250,000 m³/h design case using two-stage wet desulfurization, with stated SO₂ and particulate inlet-to-outlet design values.
Published project parameters checked
The catalog identifies a brick-kiln flue-gas project for Shaoguan Qujiang Shunfu Environmental Building Materials. The documented basis is a 250,000 m³/h gas stream treated by a sodium-calcium double-alkali, two-stage wet desulfurization process.

Engineering interpretation
Second wet desulfurization stage
Adds absorption duty and compliance margin for the stated outlet design target.
Engineering interpretation
Mist control and induced draft
A full design must remove entrained droplets and preserve sufficient fan static pressure across both towers and the stack.
Design and repeat-project checks
- The concentration figures are catalog design inputs and outlet targets, not presented as independent stack-test results.
- A repeat system requires confirmation of gas temperature, moisture, oxygen, sulfur variability, particulate properties, reagent quality and wastewater handling.
- Fan selection must include the pressure drop of both wet stages, ductwork, demisting and stack discharge at the design gas density.
Evidence boundary
The airflow and concentration values are reproduced as design parameters from the supplied company catalog. They should not be read as third-party verified commissioning results without the original signed monitoring report.
