Biomass pellet fuel

Abstract

The invention discloses a biomass pellet fuel, which comprises the following raw materials by weight: 5-25 parts of wood chips, 8-24 parts of straw, 6-24 parts of attapulgite, 4-28 parts of montmorillonite, 6-28 parts of red mud, 3-33 parts of dimethylacetamide, 10-40 parts of coal gangue powder, 4-24 parts of willow wood chips, 7-21 parts of ammonium dihydrogen phosphate, 6-18 parts of propanediol butyl ether, 3-25 parts of agricultural and forestry waste, 4-20 parts of calcium carbonate, 2-18 parts of lignite, 4-18 parts of a combustion-supporting agent, 6-18 parts of a potassium removing agent, and 6-14 parts of a safety stabilizer. The biomass pellet fuel of the present invention has advantages of good environmental protection performance, high energy utilization rate, reduction of corrosion on equipment, and the like.

Description

technical field [0001] The invention relates to the field of fuel processing, in particular to a biomass particle fuel. Background technique [0002] Biomass fuel is a block-shaped environmentally friendly new energy produced by processing straw, straw, rice husk, peanut husk, corncob, camellia husk, cottonseed husk, etc., as well as "three leftovers". Biomass pellets are typically 610 mm in diameter. According to the biomass particle classification standards of Sweden and the European Union, if the intermediate classification value is taken as an example, the biomass particles can be roughly described as the following characteristics: the diameter of biomass particles is generally 6-8 mm, and the length is its diameter 4~5 times of that, the broken rate is less than 1.5%~2.0%, the dry basis moisture content is less than 10%~15%, the ash content is less than 1.5%, the sulfur content and chlorine content are both less than 0.07%, and the nitrogen content is less than 0.5%. ...

AI Technical Summary

Problems solved by technology

[0003] At present, biomass pellets have the following advantages: 1. Biomass pellet fuel has a large calorific value, about 3900-4800 kcal / kg, and the calorific value after carbonization is as high as 7000-8000 kcal / kg; 2. Biomass Pellet fuel has high purity and does not contain other sundries that do not generate heat. Its carbon content is 75-85%, ash content is 3-6%, water content is 1-3%, absolutely does not contain coal gangue, stones, etc. do not generate heat but are consumed Hot impurities will directly reduce the cost for the enterprise; 3. Biomass pellet fuel does not contain sulfur and phosphorus, does not corrode the boiler, can prolong the service life of the boiler, and the enterprise will benefit a lot. and other problems, the energy utilization rate is low in the process of use, which is inconvenient for people to use,
