Abstract

The invention relates to a bamboo pellet fuel and a manufacture method thereof, belonging to the technical field of biomass energy utilization. The bamboo pellet fuel is characterized in that raw materials in the fuel at least comprise 60 percent of bamboo bits and the balance of wood bits or straw bits, wherein the water content of the bamboo fuel is less than 10 percent, the combustion value is4-50-4800kcal / kg, the ash content is 1.0-1.5 percent, the sulfur content is not more than 0.06 percent, the density is not less than 1.1g / cm<3> and the accumulation density is not less than 0.68g / cm<3>. The bamboo pellet fuel has the advantages of large combustion value, low ash content and low content of harmful materials. The bamboo pellet fuel has faint scent during the combustion and a function of refreshing and restoring consciousness.

Description

technical field [0001] The invention relates to a bamboo particle fuel and a manufacturing method thereof, belonging to the technical field of biomass energy utilization. Background technique [0002] Many of the current biomass pellet fuels are compressed from agricultural waste such as straw and peanut shells. For example, the Chinese patent No. 200610046801.7 discloses a "biomass pellet fuel", which is made of 92-94 parts of straw powder, 1-2 parts of mugwort and 5-6 parts of water and extruded by a granulator. Granules; the patent No. is the Chinese patent of 200710034411.2, which is pressed into granules after being mixed with sweet potatoes or potatoes with a weight ratio of 100:2-5 by the biomass pellet fuel with a particle size below 14% and a particle size of less than 8mm. The disadvantage of this type of pellet fuel is the low combustion value. There are also biomass pellet fuels that use sawdust as the main raw material, such as the Chinese patent No. 200410046...
