Problems solved by technology

[0003] However, the existing biomass fuel particles often have low combustion value, short combustion time, and are not easy to form. The powdery raw materials are easy to raise dust during the drying process and transportation process, causing serious environmental pollution, and the production efficiency is also low. It is difficult to meet the existing market requirements. needs

Abstract

The invention discloses a biomass fuel having a high fuel value, and a preparation method thereof. The biomass fuel comprises, by weight, 40-50 parts of straws, 56-64 parts of Diaphragma juglandis, 11-19 parts of nanometer zinc oxide, 5-12 parts of peroxidase and 8-16 parts of cerium acetylacetonate. The preparation method comprises the following steps: crushing the straws and Diaphragma juglandis, adding water, carrying out heating treatment, adding the peroxidase, sealing and stirring the heated mixture and the peroxidase, mixing obtained mixture with the nanometer zinc oxide and cerium acetylacetonate, cooling the obtained mixture to -5-0 DEG C, carrying out pressurizing heat insulation, heating the obtained mixture to 50-55 DEG C according to a rate of 5 DEG C / 0.5 h, carrying out vacuum pumping during the heat insulation period every 1 h for 10 min, and cooling the mixture to room temperature in order to obtain the biomass fuel. The biomass fuel has the advantages of low water content, high lignin content, high fuel value, long burning time, no smoke or smell in the burning process, cleanness, environmental protection, high forming rate, small size, large specific gravity, high binding capacity of all raw materials, no dust pollution, large density, and wide application range, and can be used in industrial and agricultural production, power generation, heating supply warming, burning boilers, cooking and so on.

Description

technical field [0001] The invention relates to the field of fuel technology, in particular to a biomass fuel with high combustion value and a preparation method thereof. Background technique [0002] 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.). The main difference is 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 MouldingFuel, 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 be ...
