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.

A waste processing apparatus may include a pyrolyser and a feed assembly. The feed assembly may include a feed duct including a waste inlet configured to receive waste. The feed duct may further include a waste outlet configured to discharge the waste from the feed duct to the pyrolyser. The feed assembly may also include a feed screw disposed within the feed duct configured to convey the waste from the waste inlet to the waste outlet. The feed assembly may further include a rotary drive configured to cause the feed screw to convey the waste from the waste inlet to the waste outlet. The feed assembly may also include a rotational resistance sensor configured to monitor a parameter related to resistance to rotation. The feed assembly may further include a rotary drive controller configured to reduce, based on the parameter, a rotary output speed of the rotary drive.

A system having a hopper that receives fuel pellets and direct the pellets under gravity feed to an auger that moves the pellets into a firepot inside a cooking chamber of a grill. The system includes a door below the auger that has a closed position that retains fuel pellets in the auger such that the fuel pellets feed to the auger, and has an opened position to allows the pellets to empty from the hopper and away from the auger. A closing mechanism allows a user to selectively open or close the door.

The present invention relates to an improved auger system for delivering combustible material to a burn box within a cooker, such as a grill or smoker. The invention features a pivotable coupling between the auger shaft and the drive motor, enabling the auger to adjust its alignment within the tube to accommodate irregularly shaped materials, thus minimizing jamming and improving the consistency of material delivery. In some embodiments, the system also incorporates a mechanism to prevent material bridging in the hopper, ensuring the continuous flow of material into the auger tube as well as an auger cover flap pivotably mounted at the outlet end of an auger tube, which is configured to control the flow of combustible material from the auger tube into the burn box.

The system also incorporates a mechanism to prevent material bridging in the hopper, ensuring the continuous flow of material into the auger tube as well as an auger cover flap pivotably mounted at the outlet end of an auger tube. A programmable controller allows users to select between variable combustible materials and regulate grill systems, allowing adjustment of cooker elements including the auger, airflow fans, and a hopper agitator to optimize combustion efficiency and maintain consistent cooking temperatures, adapting to the characteristics of each fuel type.
