With the development of the society, the development of mineral resources in recession or dried up stage, quite a number of resource-based cities in our country's economic development is in trouble, and bring a series of economic and social problems and contradictions. At present, nearly a third of the resource-based cities in our country is facing the problem of resource depletion, how to carry on the adjustment of industrial structure as soon as possible, to realize the economic transformation and sustainable development, is the urgent task faced by the city. Compared with diesel oil, natural gas, use of wood particles mechanism made of sawdust pellet fuel is a kind of clean and environment-friendly energy, and low price machine, is an effective way to realize sustainable development is a good substitute for diesel oil, natural gas. Sawdust particles machine besides there is a huge market potential, there is a great social significance:

1. The mechanism of increase of small wood particles gradually made the development of biomass energy, not only reduce the cost, and reduce the pollution of the environment.

2. Solve the rural crops straw and plant of the city garbage "double ban" of social problems, not only effectively improve the comprehensive utilization of them, but also for industrial production, biomass, restaurants, hotels, residents to provide environmental protection, a new type of environmentally friendly fuel saving.

3. Biomass energy from green plants, can consume a large amount of carbon dioxide during photosynthesis, so called zero discharge energy. Development of wood grain machine, increase the use of biomass energy, to substitute of coal, biomass fuel can reduce carbon dioxide emissions, reduce carbon oxides, nitrogen oxides, such as atmospheric pollution, reduce acid rain. To improve the energy structure, improve energy efficiency and reduce environmental pressure make a great contribution.
