CN1884454A - Biomass granule fuel - Google Patents

Abstract

The invention relates the new type fuel, comprising 92-94 parts straw powder, 1-2 parts Artemisia vulgaris and 5-6 parts water. The method comprises the following steps: disintegrating straw and Artemisia vulgaris, adding water, mixing, squeezing, and getting cylinder particle. The particle size is between 0.3 and 0.6mm, and the length is 8-12. The invention uses straw as main material, and has the advantages of non chemical preparation, non toxicant and non-contamination. Because the Artemisia vulgaris has fragrant, the fuel can produce fragrant. The product can be used in country heating.

Description

Biomass granule fuel

Technical field

The present invention relates to a kind of New-type fuel, is the biomass granule fuel that a kind of reproducible straw with farm crop etc. is made.

Background technology

At present, fuel commonly used mostly is based on coal, oil, coal gas, and these resources all are non-renewable.Straw of farm crop and faggot etc. are rural area fuel for many years, and traditional mode all is directly to burn with the mode of a heatable brick bed, kitchen range, and this mode energy efficiency of conversion is low, fuel consumption is big, and function is limited, can not be voluntarily continual and steady combustion heat supplying, intensity of combustion is low, a little less than the firepower, wastes time and energy.

In recent years, it is the method for main material production New-type fuel that people have also studied with crop stalk, it as the patent No. 02135891.5 Chinese invention patent, a kind of straw shaped fuel and preparation method thereof is disclosed, this fuel is to mix with straw fine powder and colliery powder, then through shaper machine-shaping.This kind fuel can contain objectionable constituent such as sulphur owing to contain the composition of coal gangue after the burning, can cause certain pollution to environment.

Summary of the invention

For solving the problem that prior art exists, the objective of the invention is to propose a kind of biomass granule fuel made from the straw of farm crop that does not contain any objectionable constituent.

Biomass granule fuel is characterized in that this fuel is to be made by weight ratio by following compositions:

The straw powder is more than 40 orders: 92-94 part

Argy wormwood is more than 40 orders: 1-2 part

Water: 5-6 part.

The method for making of described biomass granule fuel is: crop stalk and argy wormwood are ground into needed fine powder with pulverizer; add water then; mixed is even according to required weight; through tablets press extruding once shaped; be shaped to the cylinder shape particle; particle size is at Φ 0.3-0.6mm, the cylinder shape particle of length 8-12.

Because tablets press heats up in granulation process naturally, temperature can reach 70 ℃-80 ℃, so this fuel is not empty adding Chemical Felter in moulding process, gets final product.

The present invention compared with prior art, its novelty and creativeness are embodied in: the energy crop stalk with natural reproducible is a main raw material, does not add any chemicals, does not contain poisonous composition, burning back environmentally safe.And, add the argy wormwood that has aromatising flavour, produce aromatising flavour in the time of can making fuel combustion.The cost of this fuel is compared with coal gas with coal, and cost reduces greatly.The usefulness that this product is specially adapted to the rural area heating, makes meal, burns a heatable brick bed.

Embodiment

Embodiment 1:

Biomass granule fuel, this fuel is to be made by weight ratio by following compositions:

The straw powder is more than 40 orders: 92 parts

Argy wormwood is more than 40 orders: 2 parts

Water: 6 parts.

The method for making of described biomass granule fuel is: crop stalk and argy wormwood are ground into needed fine powder with pulverizer; add water then; mixed is even according to required weight; through tablets press extruding once shaped; be shaped to the cylinder shape particle; particle size is at Φ 0.3-0.6mm, the cylinder shape particle of length 8-12.

Because tablets press heats up in granulation process naturally, temperature can reach 70 ℃-80 ℃, so this fuel is not empty adding Chemical Felter in moulding process, gets final product.Present embodiment is that the KL120 type tablets press that adopts the Wafangdian City to celebrate rich farm equipment factory production is made.

Embodiment 2:

Biomass granule fuel,

This fuel is to be made by weight ratio by following compositions:

The straw powder is more than 40 orders: 94 parts

Argy wormwood is more than 40 orders: 1 part
