ABSTRACT:
This invention relates to improving the known process for disposing of refuse while simultaneously producing a useful gaseous product and an inert solid residue in a shaft furnace in which refuse is fed into the top portion of said furnace, an oxygen containing gas is fed into the base, and in which the organic portion of the refuse is pyrolized to char, oils and gas containing a high concentration of CO and H.sub.2, and the inorganic portion of the refuse is fluidized and tapped from the base of the furnace.
The improvement in the above-described process comprises removing a portion of the char from the furnace while retaining a sufficient amount of combustible materials in the furnace to satisfy the energy requirements of the process. The improvement permits a reduction in the oxygen requirements of the process and has a beneficial effect on the specific heating value of the fuel gas produced.
