Abstract

The present invention relates to a method and a device for reducing emission from a combustion or gasification plant, said plant having an combustion chamber housing means for insertion of a first fluid into said chamber, introduction of said fluid into said chamber being effective to reduce the emission of at least one substance from said combustion and said fluid having an optimal operating temperature range for which emissions are particularly low. The temperature is established in a volume in said combustion chamber, where said volume includes the position for insertion of said first fluid. A second fluid is inserted into said combustion chamber and is 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. A third fluid is inserted into said combustion chamber and is 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.
