Analysis on Feasibility of Engineering Application of High Efficiently Using Straw Stem Technology in North Rural Area of China

This paper presented the research results on the feasibility of the engineering application of high-efficient using straw technologies in the north rural areas of China. The biochemical conversion, the thermo-chemical conversion and the straw briquette process are all high efficiently straw stem using technology. The long wintertime and the cold climate limit the effect of biochemical conversion. The straw pyrolysis oil production technology still needs further research to promote engineering application. The straw gasification is a better technology for the high efficiently using straw stem, but the tar problem is a tough barrier. The direct combustion technology is simple and practical, but the burning efficiency should be further improved. The straw briquette technology is nearly mature for engineering application. Further more, the straw briquette has a good transport and storage properties. It can be a fuel pretreatment technology.
