High-performance biomass solid fuel and preparation method thereof

Abstract

The invention relates to the technical field of biomass fuel, in particular to high-performance biomass solid fuel and a preparation method thereof. The high-performance biomass solid fuel is preparedfrom the following components in parts by weight: 120 to 150 parts of straws, 30 to 45 parts of fruit peels, 4 to 8 parts of synergistic agent, 5 to 9 parts of combustion-supporting adhesive, 8 to 14parts of magnesium oxide, and 6 to 12 parts of carbide slag. The high-performance biomass solid fuel has the beneficial effects that the crop wastes such as the straws and the fruit peels are used asmain raw materials, so that the raw material is wide in source and low in price, not only can the waste be comprehensively utilized, the environmental pollution be reduced and the sustainable development of the resource be realized, but also the energy crisis problem at present can be effectively alleviated, and the charcoal ash after the biomass solid fuel is combusted to be used as fertilizer;and the carbide slag can reduce a combustion point of formed fuel and increase a melting point of the fuel ash, so that the problems that the existing biomass solid fuel is easy to slag, easy to accumulate and insufficient in combustion in the combustion process, and aids in the ignition of the solid fuel by arranging the magnesium oxide.

Description

technical field [0001] The invention relates to the technical field of biomass fuel, in particular to a high-efficiency biomass solid 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 of biomass is a highly polluting 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 molding fuel (Biomass Moulding Fuel, referred to as "BMF"), which uses agricultural and forestry waste as raw materials, and through crushing, mixing, extrusion, drying and other processes, it is made into various moldings (such as block Shape, granular, etc.), a new type of clean fuel that can ...

Problems solved by technology

[0005] The beneficial effects of the invention are: the present invention uses crop waste straws and fruit shells as main raw materials, has a wide range of raw materials and low prices, not only comprehensively utilizes wastes, reduces environmental pollution, realizes sustainable development of resources, but also effectively Alleviate the current energy crisis, and at the same time, the charcoal ash after burning biomass solid fuel can be used as fertilizer; carbide slag can reduce the ignition point of molding fuel, increase the melting point of fuel ash, and solve the problem of easy slagging in the combustion process of current biomass solid fuel , easy to accumulate dust, and insufficient combustion, the setting of magnesium oxide is convenient for solid fuel to be ignited
