Abstract

A gasifier of organic waste which has an insulated body with an interior cavity. A
combustion air inlet extends vertically into the interior cavity. A remote end of the combustion air inlet serves to divide the interior cavity into an upper fuel receiving portion and a lower combustion portion. A fuel entry port accesses the upper fuel receiving portion, whereby organic waste to be gasified is introduced into the upper fuel receiving portion. Smoke removal ports are positioned in the upper fuel receiving portion and smoke injection ports are positioned in the lower combustion portion of the interior cavity. Smoke circulation conduits connect the smoke removal ports with the smoke injection ports, whereby smoke is drawn from the upper fuel receiving portion of the interior cavity and introduced into the lower combustion portion of the interior cavity to enhance combustion and promote circulation.

Claims (11)

1. A gasifier of organic waste, comprising:
an insulated body having an interior cavity;
a combustion air inlet extending vertically into the interior cavity of the body, a remote end of the combustion air inlet serving to divide the interior cavity into an upper fuel receiving portion and a lower combustion portion;
a fuel entry port accessing the upper fuel receiving portion of the interior cavity, whereby organic waste to be gasified is introduced into the upper fuel receiving portion;
an ash removal opening accessing the lower combustion portion of the interior cavity, whereby ash is removed after combustion;
smoke removal ports positioned in the upper fuel receiving portion of the interior cavity;
smoke injection ports positioned in the lower combustion portion of the interior cavity;
smoke circulation conduits connecting the smoke removal ports with the smoke injection ports, whereby smoke is drawn from the upper fuel receiving portion of the interior cavity and introduced into the lower combustion portion of the interior cavity to enhance combustion and promote circulation; and an outlet from the interior cavity for gases produced as a result of gasification of the organic waste through combustion.
2. The gasifier as defined in claim 1, wherein the combustion air inlet is rotatable.
3. The gasifier as defined in claim 1, wherein a grate is positioned in the ash removal opening, and a grate agitator is provided, the grate agitator causing movement of ash through the ash removal opening.
4. The gasifier as defined in Claim 3, wherein a layer of ceramic balls are provided above the grate, the layer of ceramic balls thermally insulating the grate from excessive heat from the lower combustion portion of the interior cavity, the grate agitator agitating the ceramic balls, such that the ceramic balls serve as a ball-mill to break up clinkers formed by fusion of ash.
5. The gasifier as defined in claim 1, wherein the insulated housing is lined with refractory material.
6. The gasifier as defined in claim 1, wherein a feed auger is provided for carrying organic waste to the fuel entry port.
7. The gasifier as defined in claim 1, wherein a blow out door is provided in the housing.
8. A gasifier of organic waste, comprising:
an insulated body having an interior cavity;
a rotatable combustion air inlet extending vertically into the interior cavity of the body, a remote end of the combustion air inlet serving to divide the interior cavity into an upper fuel receiving portion and a lower combustion portion;
a fuel entry port accessing the upper fuel receiving portion of the interior cavity, whereby organic waste to be gasified is introduced into the upper fuel receiving portion;
an ash removal opening accessing the lower combustion portion of the interior cavity, whereby ash is removed after combustion;
an ash collection receptacle for collecting ash which passes through the ash removal opening;
a grate positioned in the ash removal opening;
a rotatable grate agitator adjacent to the grate for agitating the grate to facilitate the movement of ash through the grate;
means for rotating the grate agitator;
a layer of ceramic balls positioned above the grate, the layer of ceramic balls thermally insulating the grate from excessive heat from the lower combustion portion of the interior cavity, the grate agitator agitating the ceramic balls, such that the ceramic balls serve as a ball-mill to break up clinkers formed by fusion of ash;
smoke removal ports positioned in the upper fuel receiving portion of the interior cavity;
smoke injection ports positioned in the lower combustion portion of the interior cavity, combustion of the organic waste forming into a flame zone layer, a charcoal layer, and a coal layer in the lower combustion portion of the interior cavity, the smoke injection posts being positioned where the charcoal layer forms;
smoke circulation conduits connecting the smoke removal ports with the smoke injection ports, whereby smoke is drawn from the upper fuel receiving portion of the interior cavity and introduced into the lower combustion portion of the interior cavity to enhance combustion and promote circulation; and an outlet from the interior cavity for gases produced as a result of gasification of the organic waste through combustion.
9. The gasifier as defined in claim 8, wherein the means for rotating the grate agitator is a rack and pinion drive assembly.
10. The gasifier as defined in claim 8, wherein the insulated housing is lined with refractory material.
11. The gasifier as defined in claim 8, wherein a feed auger is provided for carrying organic waste to the fuel entry port.
