Suppression of the steam plume from incinerator stacks
Abstract
Abstract METHODS AND APPARATUS FOR TREATING HEATED GSES TO REMOVE PARTICULATE MATTER THEREFROM AND TO SUPPRESS STEAM PLUME FORMATION UPON DISCHARGE OF THE GASES TO THE ATMOSPHERE ARE DISCLOSED. SPECIFICALLY, THE GASES ARE DIRECTED THROUGH A FIRST HEAT EXCHANGER PASSAGEWAY TO A CONVENTIONAL SCRUBBER SYSTEM WHEREAT SUBSTANTIALLY ALL OF THE PARTICULATE MATTER IS REMOVED FROM THE GASES. THE SCRUBBER ALSO FUNCTIONS TO REDUCE THE TEMPERATURE OF THE GASES SUBSTANTIALLY BELOW THEIR DEW POINT FOR EFFECTIVELY DEHYDRATING THE GASES BY CONDENSATION OF THE WATER VAPOR CARRIED THEREBY. THE DEHYDRATED, SCRUBBED AND COOLED GASES ARE PASSED THROUGH A SECOND PASSAGEWAY OF THE HEAT EXCHANGER AND ARE REHEATED BY INTIMATE THERMAL CONTACT WITH THE GASES PASSING THROUGH THE FIRST PASSAGEWAY, THE GASES IN THE FIRST PASSAGEWAY BEING PROPORTIONALLY COOLED, THE REHEATED GASES ARE THEN DISCHARGED TO THE ATMOSPHERE. OTHER FEATURES ARE DISCLOSED.
