Pellet grills and associated methods of operation are disclosed. An example pellet grill includes a burn pot configured to combust pellet fuel received within the burn pot. The pellet grill further includes an auger configured to deliver the pellet fuel to the burn pot. The pellet grill further includes an auger motor operatively coupled to the auger. The pellet grill further includes one or more processors configured to determine whether a shutdown sequence of the pellet grill has been initiated. The one or more processors are further configured, in response to determining that the shutdown sequence has been initiated, to command the auger motor to reverse a direction of rotation of the auger. The reversal is to cause pellet fuel which the auger has not yet delivered to the burn pot to be purged in a direction away from the burn pot.

Pellet grills and associated methods of operation are disclosed. An example pellet grill includes a one or more processors configured to detect an improper shutdown of a control system of the pellet grill. The one or more processors are further configured to generate a notification in response to the control system regaining power following detection of the improper shutdown, the notification indicating that the control system was improperly shutdown. The one or more processors are further configured to cause the notification to be presented at a user interface of the pellet grill.

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 kiln system, comprising: a pre-heating chamber which is supplied with waste product; and a combustion chamber which receives the waste product from the pre-heating chamber and in which the waste product is incinerated; wherein the pre-heating chamber heats the waste product to remove moisture from the waste product prior to transfer to the combustion chamber.

Embodiments include a wood pellet burner unit with a sliding floor hopper. The wood pellet burner unit includes a wood pellet fire pit, a wood pellet kettle burner, a wood pellet barbeque burner, and/or a wood pellet smoker, or the like. The sliding floor hopper includes an upper loading section having an opening therein that receives wood pellets, and a staging section coupled to the upper loading section and stages the wood pellets received from the upper loading section. A sliding floor is disposed atop a staging surface of the staging section and through a slit in the staging section. The sliding floor oscillates between a forward position and a back position. The sliding floor oscillates between a forward position and a back position to automatically and periodically feed the wood pellets to a lower region of the wood pellet burner unit on a continuous basis.

A grilling device includes an auger feeder system, a heating element, a blower and a temperature control system. The temperature control system includes at least a first temperature sensor inside the firepot and a second temperature sensor inside a cooking chamber above the firepot. The heating element can also serve as the first temperature sensor. A method for controlling the temperature of the grill can include receiving temperature feedback information from one or more of the temperature sensors and adjusting power provided to the auger feeder system, heating element, and blower. The temperature control system produces cold smoke resulting from the combustion of lignin in solid wood fuel while minimizing temperatures inside the cooking chamber.

The present invention relates to a sealed plasma melting furnace for treating low- and intermediate-level radioactive waste, which allows the secondary pollutants to be minimized. The sealed plasma melting furnace includes: a waste supply chamber communicatively provided with a hopper; a pyrolysis chamber channel communicatively coupled with the waste supply chamber; a pyrolysis chamber having a burner mounted thereon; a melting chamber channel guiding the waste transferred from the pyrolysis chamber communicatively provided therewith to fall down; a melting chamber provided with a furnace interior portion accommodating a molten substance on a bottom surface thereof; a processed molten substance discharge channel discharging the processed molten substance generated in the melting chamber; a secondary combustion chamber channel inducing and exhausting an off-gas flow generated in the melting chamber; and a secondary combustion chamber inducing complete combustion of the off-gas input from the secondary combustion chamber channel.

A fuel material processing system includes a hopper assembly configured to receive a fuel material. A drying system is configured to remove moisture from the fuel material to generate a dried fuel material. A material delivery system is configured to provide the dried fuel material to a combustion system.

Pellet grills and associated methods of operation are disclosed. An example pellet grill includes a lid, a cooking chamber, an engine, and one or more processors. The lid is movable between a closed position and an open position. The engine is configured to output heat to the cooking chamber. The one or more processors are configured to detect a closing movement of the lid. In response to detecting the closing movement, the one or more processors are configured to command the engine to operate in an increased output mode that increases the heat output of the engine.

A wood pellet stove operable to mount to a wall includes a combustion chamber, a combustion chamber door, and a hopper. The combustion chamber has a front, back, and side. The combustion chamber door is in the front of the combustion chamber. The hopper is mounted at the side of the combustion chamber. The bottom of the hopper is below a top of the combustion chamber, and a top of the hopper is substantially coplanar with the top of the combustion chamber. The stove may also include a sight glass or fuel level monitoring system for determining a fuel level of the hopper without opening the hopper.
