The species of biomass is a lot, generally includes the following aspects：First, timber and forest industry discarded object；Second, agriculture
Industry discarded object；Third, water plant；Fourth, oilseed plant；Fifth, city and industrial organic wastes；Sixth, animal wastes.Biology
Mass-energy reserves are big, and burning is easy, pollution is few, and harmful components are low, and more characteristic is that biological mass-energy fuel burning is discharged
CO2The CO absorbed when substantially corresponding to its growth by photosynthesis2, so CO during biomass burning2Discharge capacity can be with
It is considered zero, or even has reduced and (considered to contain substantial amounts of K in plant ash after burning2CO3), this is that conventional energy resource can not
Analogy.
The Efficient Conversion of biomass energy can solve pollution and the problem of resource waste of China rural area biomass fuel, full
The production of foot rural area and the demand lived to high-grade fuel.Biomass Briquette Technologies, with reference to the characteristics of biomass, meet me
The national conditions of state, it is one of effective method of reality the most that current biomass comprehensive utilizes.The rule of Biomass Briquette Technologies
Modelling substantially increases the utilization ratio of biomass energy using will open up new using energy source approach for China rural area, and from
Fundamentally solve problem of resource waste, accomplish to gather materials on the spot, make full use of the resource of locality, meet rural area production and life energy
The wilderness demand in source, it is the effective way for improving urban residents' living environment, the quality of life of urban residents can be effectively improved,
Agroecological environment is protected, while increases the income of peasant.Sustainable bioenergy system is established, to ensureing China's warp
The sustainable development tool of Ji is of great significance.
