Abstract

The invention discloses a composite biomass fuel which comprises the following raw materials in parts by weight: 70-80 parts of a biomass raw material, 15-25 parts of anthracite powder, 2-4 parts of acombustion improver, 0.5-1 part of a foaming agent, 4-6 parts of a bulking agent and 8-10 parts of a binder. According to the biomass fuel disclosed by the invention, the proper combustion improver,sodium bicarbonate and bulking agent are selected and matched with one another, so that the biomass fuel disclosed by the invention is relatively high in combustion efficiency, relatively sufficient in combustion and good in anti-falling performance.

Description

technical field [0001] The invention relates to the technical field of biomass fuels, in particular to a composite biomass fuel. Background technique [0002] With the depletion of resources such as oil and coal, biomass fuels have gradually attracted people's attention. Biomass fuel refers to the burning of biomass materials as fuel, generally mainly agricultural and forestry wastes (such as straw, sawdust, bagasse, rice bran, etc.). It is a new type of clean fuel that uses agricultural and forestry wastes as raw materials, through crushing, mixing, extrusion, drying and other processes, into various shapes (such as lumps, granules, etc.), which can be directly burned. However, due to the tight compression of the biomass fuel, when the biomass fuel is burned, there is insufficient oxygen inside and cannot be fully burned. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a composite b...
