Description

technical field

[0001] The invention belongs to the wood particle fuel and its molding process in the application field of bioenergy. Background technique

[0002] At present, due to the reduction of non-renewable energy sources, my country is paying more and more attention to the utilization of renewable biomass energy, but the introduction of the entire technology and complete sets of equipment is expensive. Some domestic research institutes have conducted relevant research and achieved some results, but the production process is relatively complicated, and additives such as binders and combustion accelerants must be added in a certain proportion to produce qualified wood pellets. The technology in the production process The requirements are high, which leads to high product cost, and the addition of additives causes a certain degree of pollution to the environment, which affects its popularization and application.
