preparation example 1

[0062] The preparation of preparation example 1 animal bone meal:

[0063] Remove the impurities on the surface of the pig bones, mash them, place them in a tube furnace, and treat them at 800-1000°C for 45 minutes under the protection of nitrogen, and then mill them in a ball mill for 6 hours. The particle size is 0.01-1mm.

preparation example 2

[0064] The preparation of preparation example 2 basic fuels:

[0065] Basic fuel A: Wheat straw and rice straw (dry) are crushed to a particle size of 0.5-5 mm, and mixed at a mass ratio of 1:1;

[0066] Basic fuel B: Sawdust, corncobs, peanut husks, rice husks, and camellia husks are crushed to a particle size of 0.5-5mm, and mixed in equal mass proportions.

preparation example 3

Abstract

The invention provides a multi-layer structure composite biomass granular fuel with stable heat release and a preparation method. The granular fuel comprises an inner core, a control layer and a shelllayer, wherein the inner core comprises basic fuel and bentonite; the control layer comprises animal bone meal, fermented, decomposed and dried rapeseed cakes and fly ash; the control layer is of a porous structure; the shell layer comprises basic fuel, animal bone meal, bentonite and lime powder; wherein the basic fuel comprises more than two of wheat straws, sawdust, corncobs, peanut shells, rice straws, rice husks, camellia oleifera shells and cottonseed hulls. According to the invention, animal bone meal, bentonite, fermented biomass, fly ash, lime powder and the like are added into the basic fuel, and meanwhile, the product structure is controlled, so that the control on the combustion process of the biomass fuel is realized, the obtained multi-layer structure composite biomass granular fuel is slow in combustion and stable in heat release, and the application range of the product is greatly enlarged.

Description

technical field [0001] The invention relates to the technical field of biofuels, in particular to an exothermic stable multilayer structure composite biomass particle 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 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 briquette fuel, which uses agricultural and forestry waste as raw materials, and is made into various shapes (such as lumps, granules, etc.) through crushing, mixing, extrusion, drying and other processes. A new type of clean fuel that can be directly burned. Du...
