【 摘 要 】

The composition of Semi-dry Flue Gas Desulfurization ash was as follows: CaSO3 • 0.5H2O and Ca(OH)2. Most of the particle size was about 8 μm; particles were irregular and small, while the other part was rough and globular. CaSO3 strongly oxidized at about 466°C and Ca(OH)2 decomposed at ∼ 662°C. The maximum amount of phosphorus removal in Semi-dry Flue Gas Desulfurization ash was 79.898 mg/g.
