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.

Dependent claims

A mobile smokeless agricultural field burner for burning waste products in a field of soil and decontaminating the soil of said field while eliminating excess pollution release into an environment outside said field, comprising:

(a) a burn chamber oriented in direct contact with the soil of said field comprising a combustion means for burning said waste products and decontaminating the soil of said field, wherein said burning forms by-products from said waste products;
(b) an exhaust chamber separate from said burn chamber and located rearwardly of said burn chamber on said field burner, said exhaust chamber comprising a filtering means for filtering exhaust gases before their release into the environment and a tillage means for turning remaining by-products, including debris and ash, into the soil;
(c) an exhaust duct for carrying said by-products from said burn chamber to said exhaust chamber, said exhaust duct containing a combustion means for further burning said by-products;
(d) a system for generating air currents within the mobile burner to direct said by-products of said waste products from said burn chamber, through said exhaust duct and into said exhaust chamber;
(e) transportation means for moving the mobile burner from place to place when not in use;
and
(f) shielding means for preventing flames inside said burn chamber from escaping to an area outside the mobile burner.
