Problems solved by technology

[0007] It can be seen that most of the existing biomass fuel processing technologies crush the raw materials and compress them into compact granular fuels. Due to the large compression ratio of the raw material particles during combustion, the parts inside the particles are exposed to less oxygen and the combustion speed is slow. It is also difficult to completely and fully burn

preparation example Construction

[0024] The preparation method of biomass fuel provided by the present invention uses the following raw materials: 30%-40% of chaff, 30-40% of straw, 1%-1.5% of oxidant, 2%-3.5% of combustion aid, and 10% of binder -15%, loosening agent 12%-15%, wherein said loosening agent is activated carbon;

[0025] Its preparation method is as follows:

[0026] Step 1. Drying the chaff and crushing it to 50-100 mesh with a crusher; drying the straw and chopping it to 50-100 mesh; crushing the bulking agent to 0.5mm-1mm;

[0027] Step 2, mixing the chaff powder and straw powder processed in the above step 1 with the corresponding proportion of oxidizing agent and combustion accelerant;

[0028] Step 3, add a corresponding proportion of loosening agent to the raw materials prepared in the above step 2 and mix evenly;

[0029] Step 4: Add a corresponding proportion of binder to the raw materials prepared in the above step 3 and mix evenly, and process the uniformly mixed raw materials with ...

Embodiment 1

[0031] The raw materials used are: 30% chaff, 40% straw, 1% potassium permanganate as an oxidant, 0.8% alumina as a combustion aid, 0.8% iron oxide, 0.4% magnesium powder, and 12% as a binder. % bentonite, loosening agent is 15% activated carbon; dry the chaff and crush it to 100 mesh, dry the straw to 100 mesh; crush the activated carbon to 1mm; mix the processed chaff powder, straw powder and permanganate Potassium and magnesium powders are mixed evenly, then activated carbon is added and mixed evenly; bentonite is added to the raw materials prepared above, and then balls are formed by a pelletizing machine.

Embodiment 2

[0033] The raw materials used are: 40% chaff, 30% straw, 1% potassium chlorate as an oxidant, 0.8% aluminum oxide as a combustion aid, 0.8% iron oxide, 0.4% magnesium powder, and 12% as a binder. Bentonite and loosening agent are 15% coconut shell activated carbon; dry the chaff and crush it to 80 mesh, dry the straw to 80 mesh; crush the activated carbon to 0.8mm; mix the processed rice hull powder, straw powder with potassium chlorate, After the magnesium powder is mixed evenly, add coconut shell activated carbon and mix evenly; add bentonite to the above-mentioned prepared raw materials and use a pelletizing machine to form balls.

Abstract

The invention relates to a preparation method for a biomass fuel and belongs to the technical field of biomass fuels. The method comprises the steps of preparing the following raw materials: 35-45% of rice husks, 35-45% of straws, 1-1.5% of oxidizing agent, 2-3.5% of combustion improver, 8-12% of binder and 12-15% of bulking agent; crushing rice husks and straws, uniformly mixing the crushed rice husks and the crushed straws with the oxidizing agent and the combustion improver, adding the bulking agent, mixing the bulking agent with the above materials, and finally adding the binder to obtain granular products. The biomass fuel can be fully combusted. Meanwhile, the combustion product of the biomass fuel is rich in a variety of elements and can be used as an agricultural fertilizer. Therefore, the cyclic utilization of the biomass fuel is realized and the environment is prevented from being polluted.

Description

technical field [0001] The invention relates to a biomass fuel, in particular to a preparation method of a biomass fuel. Background technique [0002] With the continuous development of human society, energy issues have become a major focus of the world. Finding alternatives to non-renewable and heavily polluting fossil energy is an urgent problem that needs to be solved. Physical energy is a very viable fuel. [0003] Biomass fuel is to burn agricultural and forestry wastes such as straw, sawdust, bagasse, rice bran and other biomass materials as fuel after processing. These agricultural and forestry wastes widely exist in agricultural production and are often discarded or directly incinerated, which not only pollutes The environment also wastes resources, and its development and utilization have significant economic value. In recent years, research on biomass fuels has also made great progress. [0004] For example, the invention patent with the application number 201010...
