Problems solved by technology

In recent years, the research and application of using forest processing waste and straw to make biomass pellet fuel has gradually increased. At present, biomass energy is mainly directly formed into strips, granules or blocks by direct extrusion. , the molding thickness is getting thicker and the compaction density is getting higher and higher, which makes it difficult to ignite at the initial stage of ignition, thus causing a great reduction in the completeness of biomass fuel combustion and even generating black smoke
In turn, the defects of short burning time and low heat are caused

Description

technical field [0001] The invention relates to the technical field of biomass briquette fuel, in particular to an ignition type biomass briquette fuel. Background technique [0002] with the development of economy. Energy and environmental issues have become the focus of global attention. The energy crisis caused by the depletion of traditional fossil energy sources such as coal, oil, and natural gas and the pollution caused by their combustion have become increasingly prominent. It is imminent to develop clean and renewable energy sources. Biomass is a diverse energy resource with a wide range of sources and simple application. It has a good application prospect as an effective alternative energy source. In recent years, the research and application of using forest processing waste and straw to make biomass pellet fuel has gradually increased. At present, biomass energy is mainly directly formed into strips, granules or blocks by direct extrusion. , The thickness of the ...
