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 through direct extrusion. In the process of processing, the impact 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 mature and rot during storage, and it will also be caused by moisture content in the combustion process. Cause combustion performance; if the moisture content is low, the lamination process will be difficult, which will seriously affect the improvement of the compaction density of biomass fuel

Abstract

The invention discloses a preparation method of an aeration combustion-supporting biomass briquette. The method includes the steps of preparation of biomass fuel substrates, preparation of aeration combustion-supporting adhesives, surface treatment of the biomass fuel substrates and lamination forming. The prepared biomass briquette comprises the multiple biomass fuel substrates formed in a lamination mode. An aeration combustion-supporting adhesion layer is arranged between every two adjacent biomass fuel substitutes. Each aeration combustion-supporting 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 preparation method of the aeration combustion supporting type biomass briquette has the advantages that processing is convenient, and the product is 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 briquettes, in particular to a method for preparing aeration and combustion-supporting biomass briquettes. 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 through dire...
