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. , in the process of processing, the influence of moisture on the processing and performance of biomass fuel is unavoidable. If the moisture content is too high, it will cause the biomass fuel to form ripening and decay during the storage process, and it will also be affected by the moisture content in the combustion process. The problem causes the combustion performance to play; if the moisture content is low, the lamination process is difficult, which seriously affects the improvement of the compaction density of biomass fuel

Abstract

The invention discloses an aeration type biomass briquette. The aeration type biomass briquette comprises a plurality of biomass fuel substitutes formed in a lamination mode. An aeration adhesion layer is arranged between every two adjacent biomass fuel substitutes. Each aeration adhesion layer is a fiber adhesive and sodium bicarbonate mixture, wherein sodium bicarbonate accounts for 3-10% of the mass of the fiber adhesive and sodium bicarbonate mixture. The aeration type biomass briquette has the advantages of being high in combustion performance, good in universality, low in cost and convenient to produce on a large scale.

Description

technical field [0001] The invention relates to the technical field of biomass briquette fuel, in particular to an aeration 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. , in the process of pro...
