Abstract

The invention discloses a sawdust biomass fuel, which comprises the following raw materials (by weight): 60 parts of sawdust, 14 parts of an auxiliary agent, 6 parts of attapulgite powder, 4 parts ofrare-earth mineral, 2 parts of an oxygen producer, 0.3 part of an oxygenation synergist, 8 parts of biological asphalt, 3.5 parts of blue-green algae puree and 1.5 parts of ammonium sulfate, wherein the auxiliary agent is polyanionic cellulose. The prepared sawdust biomass fuel of the invention has high combustion efficiency and good stability, is not easy to oxidize, can be fully combusted, and can help reduce generation of harmful gases. Meanwhile, through multigroup experiment demonstration of raw material ratio, the best ratio is finally obtained. Then, the sawdust biomass fuel has the most excellent performance and has high use value and good application prospect.

Description

technical field [0001] The invention relates to the technical field of biomass fuel, in particular to a sawdust biomass fuel and a preparation method thereof. Background technique [0002] Biomass fuel refers to the burning of biomass materials as fuel, generally mainly agricultural and forestry waste (such as straw, sawdust, bagasse, rice bran, etc.), which is mainly different from fossil fuels. In the current national policy and environmental protection standards, direct combustion Biomass is a high-pollution fuel, which is only used in large stoves in rural areas and is not allowed to be used in cities. The application of biomass fuel is actually mainly biomass briquette fuel, which uses agricultural and forestry waste as raw materials and undergoes crushing, mixing, and extrusion , drying and other processes to make various shapes (such as block, granular, etc.), a new type of clean fuel that can be directly burned; as the international crude oil price continues to rise,...
