CIRKULERANDE FLUIDBAEDDFOERBRAENNING MED CO-FOERBRAENNINGSPROMOTOR OCH NEDSATT FOERBRAENNINGSLUFT.

摘要

Addition of a CO combustion promoter to a circulating fluid bed (CFB) combustion unit and reduction of the air addition rate to 100-110% of stoichiometric improves the efficiency of CO burning, reduces emissions of CO and improves the efficiency of the unit. Stable, reduced temperature operation with air rates close to stoichiometric, reduces NOx emissions. A circulating (100-400 micron particles) or fast settling (400-1200 micron particle) CO combustion promoter may be used.
