Product Description
CFB-FGD Process Overview
The Circulating Fluidized Bed Dry Flue Gas Desulfurization (CFB-FGD) system effectively removes sulfur dioxide from flue gases using calcium-based absorbents in a vertical gas-solid two-phase flow system.
Working Principle
Key Process Mechanisms
- SO₂ removal using calcium-based substances or other alkaline absorbents in circulating fluidized bed reactor
- Gas velocity of 4-6 m/s creates gas-solid sliding speeds 20-100 times greater than single particles
- Enhanced mass transfer and heat transfer rates between gas and solid phases
- Continuous particle surface renewal through violent turbulence in fluidized bed
- Desulfurization ash recycling significantly improves Ca(OH)₂ utilization efficiency
Chemical Reaction Equations
| Reaction | Chemical Equation |
|---|---|
| Primary Desulfurization | Ca(OH)₂ + SO₂ = CaSO₃·½H₂O + ½H₂O |
| Sulfur Trioxide Reaction | Ca(OH)₂ + SO₃ = CaSO₄·½H₂O + ½H₂O |
| Oxidation Reaction | CaSO₃·½H₂O + ½O₂ = CaSO₄·½H₂O |
