Abstract

The invention discloses a biomass briquette fuel which is prepared from the following raw materials in parts by weight: 30-40 parts of peanut shell powder, 20-30 parts of chestnut bark wood ash, 10-15 parts of hickory shells, 10-15 parts of sawdust, 2-5 parts of a fiber drying agent, 0.5-0.8 part of dross, 6-10 parts of an anti-coking additive and 2-3 parts of calcium oxide. The biomass fuel is renewable energy and has the advantages of energy conservation, environmental protection and high calorific value, the dechlorinating agent and the desulfurizing agent select calcium oxide, chlorine-containing waste gas generated by combustion is less, the dehydrating agent adopts the fiber drying agent, so that the fuel is low in water content and sufficient in combustion, and the fiber drying agent is prepared from pure natural plants and cannot pollute the environment; the combustion efficiency of the biomass fuel is remarkably improved, and the viscous characteristic of the sundew is utilized, so that the compressed particles can be further combined more firmly and are not prone to loosening, and the biomass fuel is suitable for long-term storage.

Description

technical field [0001] The invention belongs to the technical field of bioenergy, and more specifically relates to a biomass briquette 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, which is mainly different from fossil fuels. The content of ash powder, sulfur and nitrogen in biomass fuel is low. It is a new type of renewable fuel with clean combustion, high efficiency, environmental protection and energy saving. It can replace coal, oil, natural gas and other energy sources. Not only that, but biomass fuel can also reduce air pollution. [0003] The production process of biomass fuel is to process the loose biomass raw material through crushing, drying and other processes, and then process it into biomass solid particle fuel through ring die pressing roller extrusion molding. The particle size of biomass pellet fuel is uniform, and the un...
