Method and means for burning corncobs and corn

The method of burning particulate combustible material, comprising,

• supplying a quantity of particulate combustible material to the upper portion of a supporting surface inclined sufficiently to frictionally resist the rapid movement of combustible material downwardly thereover,
• limiting the quantity of combustible material supplied to said supporting surface, thereby forming said combustible material in a mound which substantially terminates short of the lower periphery of said supporting surface,
• igniting said combustible material,
• supplying additional combustible material to the upper portion of said supporting surface and to the ignited material whereby the ignited material is slowly moved downwardly over said supporting surface to concentrate the ignition of said combustible material at the lower periphery thereof as said material moves gradually down said inclined supporting surface.

A device of the type described, comprising,

• a support means,
• a floor means extending over a portion of said support means,
• said floor means being perforated and extending upwardly and inwardly from the peripheral portion thereof to an open central portion,
• a first conveyor means having its intake end in operative communication with the material to be burned and its discharge end in communication with said open central portion for conveying the material to be burned upwardly through said central opening for deposit on said floor means around said central opening,
• and a second conveyor means extending around the periphery of said floor means for conveying the ashes of the burned material away from said floor means,
• said floor means being pyramidal shaped, and
• said second conveyor means comprising first, second, third and fourth auger conveyors extending around the periphery of said floor means.

A device of the type described, comprising,

• a support means,
• a floor means extending over a portion of said support means,
• said floor means being perforated and extending upwardly and inwardly from the pripheral portion thereof to an open central portion,
• a first conveyor means having its intake end in operative communication with the material to be burned and its discharge end in communication with said open central portion for conveyinr the material to be burned upwardly through said central opening for deposit on said floor means around said central opening,
• and a second conveyor means extending around the periphery of said floor means for conveying the ashes of the burned material away from said floor means,
• an upstanding enclosure extending around said floor means, products of combustion being carried into the air within said enclosure when material is burned on said floor means,
• means for filtering said air,
• means for exhausting filtered air to the atmosphere,
• a third conveyor means having an intake end in operative communication with the material to be burned and a discharge end in operative communication with the intake end of said first conveyor means, said third conveyor means including opposite perforated sidewalls, and
• said means for filtering said air including means for directing said air through said opposite perforated sidewalls for depositing said products of combustion onto material in said third conveyor means.
