US Patent 11528918 Smoke tube combustion chamber

Disclosed is a smoke tube combustion chamber that combusts fuel such as wood pellets to provide heat and smoke flavor to the food being cooked. The smoke tube may include two portions that rotate about one another to receive fuel, dispose of excess fuel or fuel waste, and combust the fuel, depending on the positions of the two portions. A flow path may communicate with the smoke tube to provide the necessary air flow to circulate the smoke and heat created by the smoke tube during use. The smoke tube may be a primary or secondary heat source within the appliance.
