Today's human beings are facing tremendous energy and environmental pressures. Today's energy is mainly derived from fossil fuels, including coal, oil and natural gas.On the one hand, the application of the fossil energy to promote the development of society, but its resources are increasingly depleted, on the other hand, due to overuse of fossil energy has caused the serious environmental problems, therefore, to develop and search for new alternative energy has become the human society is one of the major problems to be solved.Biomass energy is one of the most important future alternative energy, is the inexhaustible solar warehouse, replace the fossil fuel with biomass energy, not only can reduce CO2 emissions of greenhouse gases, because can also reduce fossil fuel use and pollutants such as emissions of SO2, NOx, which plays a role of protection and improvement of the environment.The biomass gasification gas power generation will be the main way to replace fossil fuels in the future, to convert biomass by biomass gasifier to combustible gas, combustible gas (PG) technology to solve many problems in the solid biomass power generation, gas conversion more directly, the conversion rate is very high.The most frequent use of combustible gases is through combustion to generate heat.This type of application is very extensive, it contains a variety of applications in industry and life, such as drying, boiler and kitchen and so on, in most of the application process, the biomass by biomass gasifier gasification into electricity gas is the most leading in various ways.
