Abstract: The reduction of emission of sulphur dioxide from fuels containing sulphur components when such fuels are combusted. The reduction of such sulphur dioxide emissions upon the combustion of such sulphur containing fuels is accomplished by the introduction into such fuels an alkali additive which is pressure fed into such fuels at a point closely adjacent the burner structure for the combustion process thus insuring for the intimate mixture of such alkali material with the fuels to be combusted. The alkali material serves to neutralize the sulphur containing impurities which are normally caused to exit through a conventional stack exit for the exhaust gases from the burner.
