A gasifier for converting solid organic fuels to combustible gas includes a cylindrical body having insulated side walls and a gas outlet port near its base. Affixed to the top of the cylindrical tank is a conical-shaped fuel feed hopper and beneath it and within the interior of the tank is an inverted truncated one. Positioned beneath the throat of the inverted cone is a pyramidal-shaped grate for supporting the combusting solid fuel during the inversion process. Positioned beneath the grate are a series of baffles. Combustion air is drawn in through the upper portion of the tank near the base of the frusto-conical feed hopper by the action of a motor-driven fan coupled to the gasifier\s outlet port. The down draft gas flow reduces noxious fumes and pollutants while the baffles, by increasing the fluid velocity of the gases, tends to make the unit self-cleaning. The design of the hearth cone and grate also eliminates bridging of the fuel during the gasification process.

A gasification apparatus for producing combustible gases from solid organic materials comprising: (a) a base member; (b) a generally tubular body member mounted vertically on said base and having an open top; (c) a feed hopper having downwardly and outwardly sloping sides secured to said open top for receiving said organic materials to be gasified; (d) an inverted truncated cone disposed within said body member directly beneath said feed hopper for funneling the flow of said organic materials deposited into said feed hopper to a throat area; (e) means for uniformly introducing combustion air through said feed hopper and said inverted truncated cone to a combustion zone; (f) grate means disposed beneath said throat area for supporting said organic materials in said combustion zone; (g) baffle means disposed beneath said grate means in said body member for increasing the dwell time of combustion gases in the high temperature zone of said body member and correspondingly increasing the velocity of gases being drawn through said apparatus; (h) a gas exit port disposed proximate said base; and (i) blower means coupled to said gas exit port for drawing air through said means for introducing combustion air and through said combustible material supported on said grate means for supporting combustion thereof.
