Abstract

The invention belongs to the field of comprehensive utilization of biomass fuel and specifically relates to biomass particle fuel and a preparation method thereof. The biomass particle fuel is prepared from the following ingredients in parts by weight: 20 to 30 parts of bagasse, 10 to 15 parts of coconut shell powder, 5 to 10 parts of dried lotus leaves, 20 to 25 parts of crop stalks, 5 to 8 partsof peanut shell, 6 to 10 parts of bamboo sawdust, 15 to 20 parts of corncob, 15 to 20 parts of elm wood flour and 1 to 5 parts of combustion improver. The biomass particle fuel disclosed by the invention has the advantages of high combustion value, low sulfur value and high shaping rate; namely, a lower heating value is larger than 18 MJ / kg and is far higher than the average heat values of corn stalks and sorghum stalks, and the combustion efficiency of the fuel is effectively improved; nearly no sulfur dioxide or fly ash is generated, and ecological environment construction is facilitated; the biomass particle fuel is not prone to being broken. The prepared biomass particle fuel disclosed by the invention has better comprehensive performance, an application range of the biomass particlefuel disclosed by the invention is expanded, and good economic benefits can be achieved.

Description

technical field [0001] The invention belongs to the field of comprehensive utilization of biomass fuels, and specifically refers to a biomass particle fuel and a preparation method thereof. Background technique [0002] Biomass pellet fuel refers to adding crushed crop straw such as corn, wheat, cotton, rice, wheat and oil, or agricultural and forestry waste such as sawdust and leaves to the pellet forming machine, and the crushed material is pressed by rollers and molds. The friction generated by the relative motion extrudes the pelletized fuel. Biomass pellet fuel has high calorific value and is clean and pollution-free. It is a high-tech and environmentally friendly product that can replace coal energy. The produced biomass pellet fuel can be used as a special pellet fuel stove for cooking and heating, and can also be used as the main fuel for biomass industrial boilers and thermal power generation, which can replace coal. Biomass pellet fuel has the characteristics of ...
