Abstract: A method and installation for the cremation of bodies in coffins. The coffin is placed in a crematorium furnace in the wall of which at least one burner is disposed. Conbustion occurs in a chamber of the crematorium furnace without naturally-occurring air and with the burning of the coffin supplying energy along with part of the recirculated flue gas in which oxygen has been added. The flue gas fed back to the crematorium furnace is recirculated uncooled. The temperature at the crematorium furnace is maintained by the burning coffins and the oxygen-enriched recirculated flue gas.

Abstract: A method and installation for reducing emissions during the incinerating of waste results from a combustion chamber, a return situated downstream of the combustion chamber for returning a portion of a flue gas to the combustion chamber in a continuous cycle and a flue gas purification installation; and from situating the flue gas purification installation between the combustion chamber and the return, removing chlorine, heavy metal and sulfur dioxide from the flue gas produced in the flue gas purification installation, and admixing the oxygen required for combustion as pure oxygen with the flue gas to generate synthetic air in the ratio of 4:1 to 1:1, and preferably 2:1 to 1.5:1 while excluding ambient air.
