High-combustion-value biomass particle

Abstract

The invention relates to a high-combustion-value biomass particle, which is characterized by being prepared from the following components by weight percent: 30 to 50 percent of bark, 25 to 40 percent of straw, 20 to 45 percent of wood chips, and 2 to 5 percent of combustion-supporting agent. The heated potassium chlorate or potassium permanganate is subsequently decomposed by manganese dioxide to release oxygen, so that oxygen can be supplemented in the entire combustion process of the biomass fuel. The condition of partial hypoxia can be alleviated and the biomass fuel can be completely combusted. Magnesium chloride has the effect of bulking the biomass fuel and preventing coking, thus contributing to the full contact of oxygen with the biomass fuel and the complete combustion of the biomass. After the combustion-supporting agent is used, both the furnace temperature and thermal efficiency can be improved.

Description

technical field [0001] The invention relates to the field of bioenergy, in particular to a biomass particle with high combustion value. Background technique [0002] 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. [0003] 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. From the perspective of life cycle, biomas...

AI Technical Summary

Problems solved by technology

However, in the existing technology, biomass fuel particles mostly use straw as the main component, and its lignin content is low, resulting in the production of biomass fuel particles with low combustion value and short combustion time, which is difficult to meet the needs of the existing market

However, although biomass fuel particles with high lignin content have good combustion performance, their exothermic temperature is often higher than that of biomass fuel particles with straw as the main component.

Therefore, biomass fuel particles with high lignin content are often not easy to ignite, and the combustion is not complete, and cannot fully exert its characteristics
