Embodiment Construction

[0011] The specific implementation of the biomass particle fuel manufacturing method of the present invention will be further described in detail below.

[0012] Including process steps as follows:

[0013] After cleaning and removing impurities such as sawdust and straw, agricultural and forestry wastes are crushed to obtain raw materials with a particle size of 0.02-20mm. When producing high-density biomass pellet fuels with a density greater than 1g / cm3, the particle size of the raw materials is controlled at 0.02-6mm Among them, when producing high-density biomass pellet fuel with a density less than 1g / cm3, the particle size of the raw material is between 6 and 20mm.

[0014] Dry the raw materials so that their moisture content is between 5 and 15%, preferably between 8 and 10%. The purchased raw materials generally have uneven moisture content and high humidity, so they need to be uniformly dried to a suitable moisture content If the moisture content of the raw material...

Abstract

The invention provides a biomass particle fuel and a preparation method. The method comprises the following steps: cleaning and removing the impurities of the agricultural wastes such as wood chips and straws, and then crushing to obtain a raw material with the particle size of 0.02-20mm, drying the raw material to obtain the water content between 5-15%; reshaping to obtain the biomass particle fuel through an extrusion molding device; cooling and screening, removing the loose particles; drying through an air-flow machine and then packing and storing, wherein the water content is between 5-15%. The drying temperature is between 200 and 300 DEG C, the extrusion molding pressure is between 5 and 100 MPa, and the compression ratio is 1:4.5-1:9. According to the biomass particle fuel, the natural cementation component in the raw material is used for tightly combining the raw material, no extra chemical additive is required as a bond medium, the biomass particle fuel is environment-friendly type biomass fuel, the diameter of the biomass particle fuel is between 6-20mm, the length of the biomass particle fuel is 3-5 times of the diameter of the biomass particle fuel, and the water content of the biomass particle fuel is 5-10%.

Description

technical field [0001] The invention relates to a solid fuel and a manufacturing method thereof, in particular to a biomass particle fuel and a manufacturing method thereof which can replace civil and industrial coal. Background technique [0002] At present, there are many fuel manufacturing technologies that can replace civil and industrial coal, and there are many literature reports on this technology. For example, the Chinese patent document CN1353171A discloses an environmentally friendly granular fuel, whose raw materials include various plant straw scraps, water, calcium bicarbonate, combustion enhancers, binders, and the like. To a certain extent, it can replace coal, but chemical additives are added to the raw materials as a binding medium, not pure biomass fuel, and the binding medium will produce harmful gases when burned. Contents of the invention [0003] The purpose of the present invention is to solve the technical problem of adding binding substances in th...
