Abstract
Combustible debris is burned in an incinerator which has a screw conveyor penetrating a combustion chamber for moving debris therethrough. Burning of debris is initiated near one end of the combustion chamber and air for combustion is delivered through the screw conveyor and distributed throughout the chamber for assuring completion of combustion as debris is moved through the chamber.
Claims12
An incinerator for burning combustible debris and comprising elongate combustion chamber means having an entrance end for receiving debris and an exit end for discharging effluent, burner means adjacent said entrance end for igniting debris received into said chamber means, hollow screw conveyor means extending through the length of said chamber means for moving debris therethrough, and fan means operatively communicating with said screw conveyor means for impelling air flow therethrough, said screw conveyor means and said fan means cooperating for distributing throughout the length of said chamber means air in excess of that required for burning ignited debris so as to facilitate complete incineration thereof as such debris is moved through said chamber means.
An incinerator according to claim 10 wherein said screw conveyor means comprises an elongate hollow shaft means mounted for rotation within said chamber means and penetrated by longitudinally spaced apart air flow openings, drive means for rotating said shaft means, and thread means spiraled about said shaft means for engaging debris upon rotation of said shaft means and thereby for moving engaged debris.
A screw conveyor means for moving debris through an elongate combustion chamber while delivering air for combustion of the debris and comprising an elongate hollow shaft means mounted for rotation and penetrated by longitudinally spaced apart air flow openings, drive means for rotating said shaft means, thread means spiraled about said shaft means for engaging debris upon rotation of said shaft means and thereby for moving engaged debris, and fan means operatively communicating with said shaft means for impelling air flow therethrough, said thread means defining a hollow interior operatively communicating with said shaft means for receiving air flow impelled therethrough and for directing air to impinge onto debris engaged by said thread means and cooperating with said shaft means and said fan means for distributing air flowing through said shaft means therealong and thereby facilitating combustion of debris moved by said conveyor means.
A method of burning combustible debris comprising igniting debris fed into an elongate combustion chamber, moving the ignited debris through the chamber with a hollow rotating screw conveyor which extends through the length thereof, and impelling through the conveyor air in excess of that required for combustion of the debris while distributing the air throughout the length of the chamber.
