The project was initiated in December, 1970, to determine the potentials of mobile incineration as a practical means of reducing particulate emissions from combustive disposal of rice field residues. Previous studies on incinerators indicated improved combustion is possible under controlled conditions. Capacity, mobility, durability, economics, wild fire control and other problems existed. However, information on the state of the art was needed under California rice field conditions because of the continuing need to reduce all contributions to the statewide air pollution problem.

An experimental mobile field sanitizer (incinerator) was transported from Oregon to California. Test runs and modifications were made on the unit for use on rice field residues in California in the fall of 1971 and spring of 1972. Tests were also conducted in barley fields during the spring and summer of 1972 on a mobile straw burner prototype developed by an inventor in California.

Results of the tests of both units indicate that the state of the art is not sufficiently developed for use in rice field residue disposal. Projected overall costs of operation are not within the limits of economic feasibility at this time. Under reasonably good climatic conditions in California, well managed open field burns will have less particulate emissions than the incinerator tested. Under poor climatic conditions, the mobile incinerator cannot be operated in rice fields.
