  • Refuse burning process
    Patent number: 4399756
    Abstract: A process is provided for burning refuse containing polyvinyl chloride without the consequent production of phosgene. The refuse is carbonized in a rotary furnace at temperatures below 1200 degrees F., especially 700 degrees F., in an oxygen deficient atmosphere. A burnable gas containing the carbonized refuse is drawn from the furnace by an air jet wherein same is mixed with oxygen and selectively combusted. Uncarbonized refuse is collected and withdrawn after exiting the furnace. An apparatus is provided for combustion of the refuse in the nonphosgene generating process and includes the rotary furnace. Special seals are provided for the furnace to prevent excess oxygen from entering thereinto. In particular, the seals are utilized between the rotary ends of the furnace and stationary head associated with each end respectively.
