Pellet grills and associated methods of operation are disclosed. An example pellet grill includes a main body defining a cooking chamber. The example pellet grill further includes a burn pot located within the main body. The burn pot includes an upper end, a lower end located opposite the upper end, and a sidewall extending between the upper end and the lower end. The sidewall has an opening. The example pellet grill further includes an ignitor extending into the burn pot through the opening of the sidewall. The example pellet grill further includes an ignitor carrier removably coupled to the ignitor. The ignitor carrier extends away from the burn pot and is accessible from outside the main body.

Pellet grills and associated methods of operation are disclosed. An example pellet grill includes a burn pot including an upper end having a first opening, a lower end located opposite the upper end and having a second opening, and a sidewall extending between the upper and lower ends. The example pellet grill further includes a fuel grate positioned within the burn pot between the upper and lower ends. The fuel grate is configured to support pellet fuel within the burn pot. The fuel grate includes a plurality of ash openings dimensioned to enable ash produced from combustion of the pellet fuel to pass downwardly through the fuel grate toward the second opening.

Pellet grills and associated methods of operation are disclosed. An example pellet grill includes a main body defining a cooking chamber. The main body includes a first end, a second end located opposite the first end, and an outer wall extending between the first and second ends. The main body has a lateral extent defined by the first and second ends. The example pellet grill further includes a hopper mounted to a rear portion of the outer wall of the main body. The hopper includes a fuel intake opening extending from a first location within the lateral extent of the main body to a second location outside of the lateral extent of the main body.

A combustion/pyrolization system comprising a combustion/pyrolization chamber supported by the base frame, and a perforated grate forms a bottom surface of the combustion/pyrolization chamber and facilitates passage of char and boichar therethrough. The combustion/pyrolization chamber is open along at a top and an air manifold supplies a first source of combustion air across the top of the combustion/pyrolization chamber to form an air curtain. A char collection/transfer chamber is located below the perforated grate for collecting at least the char and boichar that passes therethrough, and a conveying mechanism transfers the char and boichar out of the combustion/pyrolization system for collection and use. An air plenum chamber cools the char collection/transfer chamber such that the supplied secondary air becomes heated, and the heated secondary air flows into the char collection/transfer chamber and through the perforated grate into the combustion/pyrolization chamber to provide secondary combustion air.

The present disclosure provides a pyrolysis incineration system that more effectively performs pyrolysis by increasing a combustion rate. The pyrolysis incineration system includes an incineration unit that includes a furnace having a combustion space, a rod-shaped air suction pipe installed in the combustion space, a first layer separation nozzle unit including a plurality of first concentration nozzles circumferentially disposed at the upper end of the air suction pipe, a curtain nozzle unit including a plurality of first diffusion nozzles circumferentially disposed under the first layer separation nozzle unit, at least one second layer separation nozzle unit including a plurality of second concentration nozzles under the curtain nozzle unit, and at least one circulation nozzle unit including a plurality of third concentration nozzles circumferentially disposed under the second layer separation nozzle unit and a plurality of second diffusion nozzles disposed between the third concentration nozzles.

Pellet grills and associated methods of operation are disclosed. An example pellet grill includes a main body defining a cooking chamber. The main body includes a first opening extending through a bottom portion of an outer wall of the main body. The main body further including a grease channel formed along the bottom portion of the outer wall and extending to the first opening. The example pellet grill further includes a burn pot located within the main body. The burn pot includes a lower end having a second opening aligned with the first opening. The second opening is configured to enable pellet fuel ash to pass downwardly from the burn pot onto an ash slide positioned below the second opening. The example pellet grill further includes a waste collection drawer located below the main body. The waste collection drawer is movable relative to the main body between a closed position and an open position. The waste collection drawer includes a grease bin positioned below the first opening and configured to receive grease from the grease channel when the waste collection drawer is in the closed position. The waste collection drawer further includes an ash compartment positioned below the ash slide and configured to receive pellet fuel ash from the burn pot, via the ash slide, when the waste collection drawer is in the closed position.
