Analysis on the Driving and Constraint Factors of Crop Straw Gasification and Commercialization Development
秸秆气化商业化发展的驱动与制约因素分析

Nowadays,the production of crop straw is about 0.79 billion tons every year in China,among them about 0.32-0.4 billion tons can be used as energy by combusting them directly while the rest are thrown away to the field or set on fire directly.To popularize the technology of crop straw gasification could not only decrease the local atmospheric pollution due to setting them on fire optionally and their influence on the flying-off and landing of the plane,but also have great effects on changing the villages'visages and constructing socialistic new rural areas.The analyses show,during the course of resource's commercial development of crop straw gasification,both of the prominent driving forces and the restriction factors exist at the same time.Concretely,there are three main driving forces:the farmers' needs on the high-grade energies(e.g.crop straw fuel gas)are the base to develop the resource of crop straw gasification commercially;to be favorable to fathering the pollution and protecting the environment,to alleviate the supply pressure of the commercial energy nationally,so to lay the economic and social groundwork for future commercialization;and in the first stage,to value high and promote the commercial development of the resource of crop straw gasification by the government is a driving force and opportunity.At the same time,there are two restriction factors:as the price of crop straw fuel gas is on the low side and the huff is almost impossible,the quantity of farmers to use the fuel gas is not in the great scale,the utility of fuel gas is limited,the initial investment to set up the crop straw gasification station is relatively costly,all of them make the economic benefit is not so seductive;the limitation of the activity not controlled by the market is uncovered when the government supports it,the technology of crop straw gasification is still not mature and applied very much,and standardization system to check and accept the equipments and construction process of crop straw gasification is scarce furthermore.
