Method for treating heated gases to suppress steam plume formation

Abstract

Abstract A METHOD AND SYSTEM ARE DISCLOSED FOR REMOVING PARTICULATE MATTER FROM COMBUSTION GASES AND FOR CONCOMITANTLY SUPPRESSING STEAM PLUME FORMATION. A SCRUBBER PASSES A FLUID THROUGH THE COMBUSTION GASES TO REMOVE PARTICULATE MATTER THEREFROM AND, PREFERABLY, INTRODUCES THE FLUID UNDER CONDITIONS SUCH THAT THE TEMPERATURE OF THE COMBUSTION GASES ARE REDUCED SUBSTANTIALLY BELOW THEIR DEW POINT; THIS LATTER ACTION DEHYDRATES THE GASES BY CONDENSATION OF THE WATER VAPOR CARRIED THEREBY. THE RELATIVELY HOT AND CONTAMINANT BEARING FLUID DISCHARGED FROM THE SCRUBBER IS CIRCULATED THROUGH A HEAT EXCHANGER WHEREAT IT IS UTILIZED TO PREHEAT AMBIENT AIR WHICH IS THEN INTERMIXED WITH THE DEHYDRATED COMBUSTION GASES DELIVERED TO THE SCRUBBER OUTPUT. THE INTERMIXED AIR AND COMBUSTION GASES ARE DISCHARGED TO THE ATMOSPHERE THROUGH A CONVENTIONAL STACK. THE RELATIVELY HOT SCRUBBER FLUID, COOLED BY ITS PASSAGE THROUGH THE HEAT EXCHANGER, IS RECIRCULATED TO THE SCUBBER FOR REPEATED USE, PREFERABLY AFTER THE FLUID HAS BEEN CLARIFIED. OTHER FEATURES ARE DISCLOSED.
