Abstract:
A method for reducing emissions from a combustion or gasification plant, said plant having a combustion chamber housing means for insertion of a first fluid into said chamber, introduction of said first fluid into said chamber being effective to reduce the emission of at least one substance from said combustion and said first fluid having an optimal operating temperature range for which emissions are particularly low, characterised in that said method comprises the steps of,establishing the temperature in a volume in said combustion chamber, where said volume includes the position for insertion of said first fluid, inserting into said combustion chamber a second fluid effective to reduce the temperature in said volume in said combustion chamber, if said temperature is established to be higher than said optimal temperature range, and inserting into said combustion chamber a third fluid effective to increase the temperature in said volume in said combustion chamber, if said temperature is established to be lower than said optimal temperature range.
