Abstract

The invention relates to relates to the biological energy field, and concretely relates to a biomass fuel having a high fuel value, and a preparation method thereof. The biomass fuel having a high fuel value comprises 20-40wt% of tree branch, 30-50wt% of bamboo sawdust and 20-40wt% of tree leaf. The biomass fuel has a low water content and a high lignin content; and compared with routine biomass fuel particles obtained after the compression molding of straws, the biomass fuel obtained in the invention has the advantages of high fuel value, long combustion time, and no emission of harmful gases or acidic gases after the combustion.

Description

[0001] technical field [0002] The invention relates to the field of bioenergy, in particular to a high combustion value biomass fuel and a preparation method thereof. [0003] Background technique [0004] At present, most of the fuels used by people are fossil energy such as coal, oil, and natural gas, which are non-renewable resources. They will gradually be exhausted under the large-scale exploitation of human beings, and a large amount of toxic gases will be emitted into the air during combustion, causing air pollution. Serious pollution, for this reason human beings are looking for renewable clean fuels to replace. [0005] Agricultural and forestry wastes, such as straw, sawdust, bagasse, rice bran, etc., are used as biomass fuels as green energy, fuels encouraged by national policies, and have the following characteristics: carbon dioxide absorbed through photosynthesis during biomass growth and carbon dioxide released by combustion The total amount is equivalent....
