ABSTRACT:
A smokeless mobile agricultural field burner for burning agricultural waste products, mainly rice straw, in the field without releasing excessive air pollution into the environment. The burner consists of a main structure, either self-propelled or towed, that serves as a burn chamber. The sides, top and rear of the main structure are enclosed, while the front and bottom are open, allowing fire to come into contact with the ground to provide sterilization benefits to the soil thereby helping to control soil contamination. Destruction of the waste products is facilitated by a series of primary burners in the burn chamber. Smoke, debris and ash resulting from the primary burn are channeled through the interior of the burner into exhaust ducts by air currents generated by a blower mounted on the outside of the main structure. Once in the exhaust ducts the smoke and debris is destroyed by a set of afterburners, then allowed to escape to an exhaust chamber. In the exhaust chamber, the ash is allowed to drop to the bottom of the chamber and is tilled into the soil, while the hot air rises to the top of the chamber and is released into the environment through a series of air filters.
