A method and apparatus is disclosed for recovery of combustible gas formed from combustible refuse or vegetable matter in an enclosed space from which the combustible gas is collected. Water can be injected into the apparatus and the decay process initiated and promoted by activating a heating element projecting upwardly from the base of the apparatus into the material undergoing decomposition. The combustible gas contains a substantial proportion of methane.

Apparatus for anaerobic decomposition of organic refuse into a gas containing a substantial proportion of methane comprising a tank, collecting means near the upper portion of said tank, and heating means near the lower portion of said tank, said heating means comprising a base plate having an upwardly projecting pipe sealed to the base plate around an aperture in the base plate, together with a heating element located beneath said base plate for transfer of heat interiorly into said pipe and thence from said pipe by conduction to the contents of the tank, said tank having injection means for controllably introducing water into said tank, whereby a desired degree of heating can be furnished deeply into the organic refuse by conduction through the pipe, the tank being an upright cylinder and said collecting means comprising a cone assembly having an upright nose and lower portion sealingly contacting the upper portion of said cylindrical tank, wherein said collecting means further comprises a fan assembly located in the upper portion of said cone assembly for directing gas upwardly toward said nose, the fan assembly including a spark-free explosion-proof motor mounted to a motor support beam and fastenable to opposite sides of the lower portion of said cone assembly, whereby said gas is upwardly directed by the fan assembly towards said nose, said gas being removable from said cone assembly at the nose, wherein further said cone assembly is sealingly attached to said tank by tension means between said base plate and mounting brackets on the lower portion of said cone assembly, said tension means comprising tie rods longitudinally tightenable by turnbuckles, whereby uniform sealing pressure is applicable between the tank and base plate.
