Wood pellets are after coal, oil and natural gas to become the fourth largest energy. Experts predict that the
biomass particles are likely to be 40% sustainable energy system in an important part of the future, in the next
century, biofuels will account for the total fuel consumption.
As China's economy continues to develop, the growing problem of energy shortage. In order to solve the energy
crisis and reduce pollution of the environment, protect the ecological environment, it is particularly important to
the development and utilization of biomass energy. Wood pellets crops such as straw, rice husk, sawdust and
other agricultural waste first through a wooden hammer mill grinding, and then into the wooden granulator to
form the solid biomass particles. Then, they can be used as direct fuel combustion.
In other countries, the wood pellet machine has matured, such as Denmark, Germany, Belgium, the United
States, Japanand other countries have realized the commercialization process, its products are mainly used in
furnaces, boilers, and power generation. Currently, our research and development of biomass pellet machines
have also been used in the production. Pollutant emissions are lower than coal, it is an efficient, clean, renewable
energy, at the same time, it is very prominent use machining feed.
In the present, the main rod shape biomass molding, blocks and granular. The shape of multi-fuel processing
method is the traditional mode of production, it has some problems, like wide high energy consumption, serious
wear, short life.
In order to solve the above problems, we have the following ways.
☆ increase in research investment. Active research and development of new technology, new equipment, reduce
energy consumption, lower production costs.
☆ introduction of foreign advanced equipment. Take the essence, to the dregs, the formation of industrial pro
duction.
☆ government support. The government should give some financial subsidies, the company in order to reduce
product cost.
