    • THERE IS DISCLOSED A MUNICIPAL INCINERATOR PLANT IN WHICH A HIGH PRESSURE STEAM BOILER IS SO ARRANGED THAT HOT COMBUSTION GASES FROM THE INCINERATOR ARE COOLED BY PASSAGE THERETHROUGH TO A TEMPERATURE COMPATIBLE WITH THE CONSTRUCTION MATERIALS OF DUST COLLECTING AND BLOWER EQUIPMENT THROUGH WHICH THE COMBUSTION GASES FLOW TO A STACK. SUCH GASES ARE THEREBY COOLED AND CLEANED WITHOUT WATER SPRAYS AND THE STEAM SO GENERATED IS IN PART CONVERTED INTO MECHANICAL ENERGY FOR OPERATION OF SOME COMPONENTS OF THE INCINERATOR SYSTEM. THE INCINERATOR STACK HAS CONCENTRIC INNER AND OUTER FLUES, AND THE HOT COMBUSTION GASES ARE DISCHARGED INTO THE INNER FLUE. A BLOWER, OPERATED BY THE HIGH PRESSURE STEAM, CIRCULATES AIR THROUGH A CONDENSER TO CONDENSE THE EXHAUST STEAM AND HEAT THE AIR. THE AIR SO HEATED IS DISCHARGED INTO THE OUTER CONCENTRIC FLUE SO THAT THE COMBUSTION GASES LEAVE THE STACK SURROUNDED BY AN ENVELOPE OF RISING CLEAN AIR, RESULTING IN THE PRODUCTS OF COMBUSTION BEING CARRIED HIGHER ABOVE THE STACK, ESPECIALLY IN PERIODS OF CALM AIR, BEFORE THEY DIFFUSE INTO THE ATMOSPHERE THAN WOULD OTHERWISE BE THE CASE. THE BLOWER ABOVE REFERRED TO IS DRIVEN BY A TURBINE WICH IS OPERATED AS A PRESSURE REGULATOR FOR THE HIGH PRESSURE STEAM GENERATED BY THE BOILER.
