Zero test emissions of sulphur dioxide from large coal under staged fluidized bed combustion
1997
Khan, W. Z. | Gibbs, B. M.
This paper reports the emissions of SO₂ from large coal under staged combustion without any additive. A stainless steel combustor, 2 m high and 0.3×0.3 m in cross section was used. Fluidizing air was supplied through a multihole distributor. An adjustable secondary air injector was used along the vertical axis of the combustor to introduce secondary air in the freeboard. From 0–40% of total air was injected in the freeboard above the bed. The experiments were carried out at fluidizing velocities of 1–2 m s⁻¹, bed temperatures of 1103–1153°K, 20–40% excess air, and bed particle sizes of 665μm. Bed temperature and level of air staging had the most significant effect on SO₂ emissions.
