Embodiment 1

[0013] 20% peanut shells, 20% sawdust, 40% rice husks, 12% waste oil, 7% waste coal gangue powder, and 1% calcium oxide. First, crush peanut shells, wood chips and rice husks, and control the particle size between 1-2 mm, and then crush the coal gangue to within 0.5 mm; send the above-mentioned crushed raw materials into the mixing bin according to the ratio, and add oil and calcium oxide , mixed evenly, and sent to a granulator for compression; then sieved and packaged to obtain the product. The size of the obtained composite biomass particle fuel is generally cylindrical particles with a diameter of 6-10 mm and a length of 24-40 mm.

Embodiment 2

[0015] 15% of peanut shells, 15% of sawdust, 50% of rice husks, 9.5% of waste oil, 10% of waste coal gangue powder, and 0.5% of calcium oxide. First, crush peanut shells, wood chips and rice husks, and control the particle size between 1-2 mm, and then crush the coal gangue to within 0.5 mm; send the above-mentioned crushed raw materials into the mixing bin according to the ratio, and add oil and calcium oxide , mixed evenly, and sent to a granulator for compression; then sieved and packaged to obtain the product.

Embodiment 3

[0017] 18% peanut shells, 18.6% sawdust, 48.6% rice husks, 8% waste oil, 6% waste coal gangue powder, and 0.8% calcium oxide. First, crush peanut shells, wood chips and rice husks, and control the particle size between 1-2 mm, and then crush the coal gangue to within 0.5 mm; send the above-mentioned crushed raw materials into the mixing bin according to the ratio, and add oil and calcium oxide , mixed evenly, and sent to a granulator for compression; then sieved and packaged to obtain the product.

Abstract

The invention discloses a composite biomass granular fuel and its processing technology. The formula of the composite biomass granular fuel comprises the following components: by weight, 15-20% of peanut shell, 15-20% of wood chip, 40-50% of rice husk, 8-12% of grease, 6-10% of a gangue powder and 0.5-1% of calcium oxide. The processing technology comprises the following steps: crushing peanut shell, rice husk and wood chip into powders according to the above proportions of the formula, adding grease, gangue powder and calcium oxide, uniformly mixing, compressing, screening, and packaging to prepare the biomass granular fuel. The composite biomass granular fuel prepared in the invention has high fuel value, is not easy to form slag, and can be widely applied in various biomass combustion apparatuses.

Description

technical field [0001] The invention relates to the technical field of biomass particle fuel, in particular to a composite biomass particle fuel and its processing technology. Background technique [0002] The rapid economic development is inseparable from energy, and the shortage of traditional fossil energy oil, natural gas and coal is becoming more and more serious. Biomass energy, as the fourth largest energy source, has become an energy source with great development potential among new energy sources due to its renewable and zero-carbon emission characteristics. Peanut husks, rice husks, and sawdust, which are usually discarded during processing, can be used as raw materials for biomass pellet fuels, which can be further compressed to become efficient carbon sources. However, the current biomass pellet fuel has the defects of low calorific value and high combustion slagging, which is not conducive to popularization and utilization. Contents of the invention [0003]...
