Flue Gas Desulfurization System with Dry Sorbent Injection
This system utilizes dry spray absorption technology to remove sulfur dioxide from flue gases. A lime slurry is dispersed into the flue gas stream, promoting SO2 absorption and producing a dry product that is then collected.
Technical Specifications
Overview
Efficient Dry Spray Absorption Technology
This Flue Gas Desulfurization (FGD) system utilizes Dry Sorbent Injection and spray dryer absorber modules to effectively remove pollutants like SO2, SO3, HCl, and HF. The technology is designed for low capital investment and minimal O&M costs, making it a cost-effective solution for power stations. Its compact structure and high availability ensure reliable performance in demanding industrial environments.

Absorption and Collection
Untreated flue gas enters the absorber where it contacts a fine spray of lime slurry dispersed by a rotary atomizer. The pollutants are rapidly absorbed and converted into dry reaction products. These products, along with fly ash, are then efficiently removed by a downstream fabric filter or electrostatic precipitator.
