Crop straw biomass fuel

Abstract

The invention discloses a crop straw biomass fuel, which is prepared by uniformly mixing and compressing the following materials by mass: 50-60% of biomass charcoal powder, 30-40% of city organic solid garbage debris, 1-10% of coal powder, 1-2% of coal tar, 0.2-0.5% of a sulfur fixing agent, and 0.1-0.3% of ferrous sulfate, wherein the outer surface of the biomass granule fuel is wrapped with a layer of biomass polyester. With the technical scheme of the present invention, the biomass energy, the fossil fuels and the city organic solid garbage are organically combined, such that the produced biomass granule fuel has advantages of good adhesion, high combustion value and low combustion pollution, almost does not produce sulfur dioxide and fly ash, and is conducive to the construction of theecological environment; and with the biomass polyester wrapped on the outer surface, the storage and the transportation of the fuel are convenient, and the particles are not easy to crack.

Description

technical field [0001] The invention relates to the field of new energy fuels, in particular to an environmentally friendly and pollution-free biomass particle fuel. Background technique [0002] Biomass solid fuel is a way of utilization of biomass energy, and its production raw materials are forestry "three leftovers" (wood processing residues, forest harvesting residues, wood making residues), various wood scraps, wood waste , crop straw, and shrubs. The production process is to process the biomass raw material with loose texture and low capacity density through crushing, drying and other processes, and then process it into biomass solid particle fuel through ring molding and pressing roller extrusion molding. The particle size of biomass pellet fuel is uniform, and the unit density can reach 1~1.4g / cm 3 , the strength is increased, the transportation and storage are convenient, the combustion performance is obviously improved, the energy utilization rate after combusti...

Problems solved by technology

[0004] However, judging from the content disclosed in the prior art, the effect of using lignin alone as a binder is not good, and the granular fuel is easily broken during transportation, and the fuel combustion performance of the fuel made from biomass materials alone It is also lower than that of fossil fuels, and the combustion furnaces used in China have not been able to fully utilize the combustion heat of this biomass pellet fuel, resulting in heat loss
