Problems solved by technology

[0005] However, at present, the biomass solid molding fuel produced with rice husk, straw, cotton stalk, and fungal residue as a single raw material has a low calorific value, and is prone to insufficient combustion, slagging, and a lot of ash during the combustion process. The gas seriously corrodes the combustion equipment, and the fuel utilization rate and fuel efficiency are not high

Abstract

The invention discloses a preparation method of a self-oxygen-supply type biomass fuel, and belongs to the technical field of biomass fuels. Various materials with simple sources can be adopted; afterthe pretreatment, fermentation is carried out, a part of auxiliary agents is added, and microwave treatment is carried out; the raw materials are mixed and then powdered; a layered paving and fillingbox is used for paving and filling the raw materials layer by layer; spontaneous combustion cracking-assisting wires are innovatively introduced and put into each layer of raw materials; oxygen supply particles are wrapped by a flammable material; the oxygen supply particles are decomposed under the action of high temperature to release oxygen; the immediate combustion fuses inserted into the spontaneous combustion crack-assisting wires are immediately combusted to release a large amount of heat; the consumption and oxygen release of the spontaneous combustion crack-assisting wires are further promoted along with multiple tiny explosion impacts, finally expanded cracks are formed in the biomass fuel, the biomass fuel is forced to crack and crush, oxygen is directly provided from multiplepositions in the biomass fuel, oxygen needed by combustion of the biomass fuel is maintained, the combustion is more sufficient, and the fuel utilization rate and the fuel efficiency are greatly improved.

Description

technical field [0001] The invention relates to the technical field of biomass fuels, in particular to a method for preparing self-oxygenated biomass fuels. 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 briquette fuel, which uses agricultural and forestry waste as raw materials, and is made into various shapes (such as block, granular, etc.) through crushing, mixing, extrusion, drying and other processes. A new type of clean fuel that can be directly burned. [0003] Biomass fuels are mainly divided into sol...
