Embodiment 1

[0026] The biomass molding fuel of the present invention is formed by pressing and molding through a granulator after pulverized and dried biomass raw material particles are mixed with fuel additives.

[0027] Wherein, based on the weight of the biomass raw material particles, coal tar with lubricating and combustion-supporting functions is added, and the weight percentage is 0.5%. Adding hot grease can facilitate the mixing with raw materials, increase the temperature of raw materials, soften the raw materials and make them easier to shape, and the grease itself has a lubricating effect; it acts as a binder after the particles are cooled, enhances the strength of the particles, and can also enhance the strength of the particles. The water resistance of the particles during storage and transportation; when the particles burn, the grease acts as a combustion aid.

[0028] Wherein, based on the weight of the biomass raw material particles, quicklime which can reduce emissions of...

Embodiment 2

[0033] As another kind of scheme of the present invention, other parts are identical with embodiment 1, and difference is:

[0034] Based on the weight of biomass raw material particles, adding 0.01%-0.5% of potassium permanganate or potassium chlorate can make combustion more fully, effectively utilize biomass energy, reduce smoke pollution and fuel cost.

Embodiment 3

[0036] As another kind of scheme of the present invention, other parts are identical with embodiment 1, and difference is:

[0037] For relatively dry raw materials, a certain amount of papermaking waste liquid can be added to the biomass raw material particles.

Abstract

The invention discloses biomass molding fuels. The fuels are granulated and molded after biomass material particles and a fuel additive are mixed, wherein, based on the weight of the biomass material particles, the fuel additive comprises the following components in percentages by weight: 0.1-5% of grease, 0.1-2% of sulfur fixation agent and 0.1-0.5% of combustion improver. The biomass molding fuel obtained in the invention is a high grade clean fuel suitable for use in industrial boilers and can be directly burned in various BMF (Biomass molding fuel) boilers.

Description

technical field [0001] The present invention relates to the utilization of biomass energy, in particular to a biomass molding fuel (Biomass Pellet or Biomass Moulding Fuel, referred to as "BMF"). Background technique [0002] At present, most of the fuels used by people are fossil energy such as coal, oil, and natural gas, which are non-renewable resources. They will gradually be exhausted under the large-scale exploitation of human beings, and a large amount of toxic gases will be emitted into the air during combustion, causing air pollution. Serious pollution, for this reason human beings are looking for renewable clean fuels to replace. [0003] Biomass fuel (such as agricultural and forestry waste, such as straw, sawdust, bagasse, rice bran, etc.) is a green energy source, and is a fuel encouraged by national policies. It has the following characteristics: 1. It can realize the reduction of greenhouse gas CO 2 Ecological "zero" emission: the energy of BMF comes from the...
