Embodiment 1

[0021] A novel biomass industrial fuel, the preparation method is as follows:

[0022] 1) Crush corn stalks, soybean stalks and peanut shells to a particle size of 8 mm;

[0023] 2) Mix the crushed corn stalks, soybean stalks, peanut shells and polyethylene oxide with a concentration of 1 g / L in a mass percentage: 55%: 20%: 15%: 10%;

[0024] 3) The above-mentioned uniformly mixed mixture is dried with hot air blower until the moisture content of the mixture is 15%, the speed of the blower is 2200r / min, and the temperature of the hot air is 80°C;

[0025] 4) Extrude the dried mixture through a roller-type granule molding machine at room temperature, and the molding pressure is 70MPa;

[0026] 5) cooling the biomass industrial fuel obtained after forming to normal temperature, and packing.

[0027] According to the provisions of GB / T28731-2012, the combustion ash of the obtained biomass industrial fuel is measured. After the combustion of the biomass industrial fuel, there is...

Embodiment 2

[0029] Repeat Example 1, the only difference is that the molding pressure in step 4) is changed to 90MPa, and other conditions remain unchanged, to obtain biomass industrial fuel, and the combustion efficiency of the fuel reaches 97%.

Embodiment 3

[0031] Repeat Example 1, the only difference is that step 3) the water content of the mixture is changed to 12%, and other conditions are unchanged, to obtain biomass industrial fuel, and the combustion efficiency of the fuel reaches 97%.

Abstract

The invention discloses a novel method for preparing biomass industrial fuel. The novel method includes smashing raw materials; mixing the raw materials and polyethylene oxide with one another; heating and drying mixtures until the moisture content of the mixtures reaches 5-20%; carrying out normal-temperature extrusion forming; carrying out cooling to obtain the biomass industrial fuel. The novelmethod has the advantages that the novel method is simple, and the biomass industrial fuel prepared by the aid of the method is excellent in water seepage resistance; good combustion effects can be realized by the biomass industrial fuel, the biomass industrial fuel is integrally free of deformation and is difficult to fall apart, high in ash melting point and free of slag bonding or ash deposition, and the novel method is applicable to industrial production.

Description

technical field [0001] The invention relates to a preparation method of industrial fuel. More specifically, it relates to a preparation method of a novel biomass industrial fuel. Background technique [0002] Biomass briquette fuel is a high-efficiency fuel made of agricultural and forestry waste, such as straw, rice husk, peanut shell, wood chips and branches, etc., processed under specific technological conditions through dense processing and molding equipment of biomass solid fuel. An environmentally friendly, renewable energy source. The combustion temperature of biomass briquette fuel can reach above 1060℃. Because of its high volatile content, high carbon activity, low N and S content, low ash content and zero CO2 emission in the combustion process, biomass briquette fuel is especially suitable for combustion conversion and utilization, and is a high-quality fuel. As far as the basic national conditions and biomass utilization level are concerned, it is undoubtedly ...
