Slagging-combustor sulfur removal process and apparatus

摘要: In the operation of a slagging combustor, including an apertured baffle defining part cylindrical combustion chamber having head end which includes nozzle for injection sulfur-containing particulate carbonaceous material to be combusted in whirling oxidant flow field, there is injected sulfur sorbent at aperture towards react with released sulfur. The into zone from location near exit thereof. Fuel center end. A relatively fuel-rich recirculation established and maintained along longitudinal axis surrounded by oxygen-rich annular region. Sorbent mixes intimately with, flows co-currently recirculating gases, generally toward zone, whereby mixture gaseous products are temperatures stoichiometric conditions favoring conversion compounds that dissolve molten slag.
