In addition to a small number of straw used as feed and return to the field, there are still a lot of discarded or even illegally burned straw, polluting the environment and wasting resources. Straw gasifier produced by our factory, using crop straw gasification, used for daily cooking and heating, last year the output of about two million yuan of products, exported to Shanxi, Henan, Shandong and other places. Save resources, reduce farmers' oil spending, welcomed by farmers. It is proposed to improve the ventilation casting system, optimize the furnace structure, increase the burning time, each burning time is not less than three hours, add appropriate catalyst to eliminate the odor, so as to make it more reasonable and perfect.
