Abstract
A biomass fuel is composed of the following components in parts by weight: 50 to 60 parts of biomass carbon powder, 10 to 20 parts of coal powder, and 5 to 10 parts of combustion promoter. The biomass fuel is prepared by the following steps: mixing a wood material (60 to 70 wt%) with crop straws (30 to 40 wt%), drying, grinding, mixing, pressing, and moulding. The external surface of the biomass fuel is cover by a layer of polyester originated from a biomass resource, and the main repeat units of the polyester are dicarboxylic acid units and glycol units. The combustion promoter is composed of 30 to 40 wt% of talcum, 30 to 50 wt% of slag of sulfuric acid production, 15 to 20 wt% of magnesium chloride block, and 3 to 5 wt% of sodium nitrate. The biomass energy and mineral fuel are combined organically, and the provided biomass fuel has the advantages of good caking ability, high combustion value, and little pollution, barely generates sulfur dioxide and fly ash, and thus protects the environment.
Description
Technical field
The invention belongs to technical field of new energies, be specifically related to a kind of biomass fuel.
Background technology
Economic fast development be unable to do without the energy, and the problem in short supply of traditional fossil energy oil, Sweet natural gas and coal is day by day serious.Biomass energy is as the fourth-largest energy, and the feature such as, zero carbon emission renewable with it, becomes a kind of energy that development potentiality in new forms of energy is larger.
Biomass solid fuel is a kind of Land use systems of biomass energy, and its raw materials for production are forestry " three surplus things " (wood machining residues, forest harvesting residuum, producing material residuum), various wooden tankage, wood wastes, agricultural crop straw and shrub etc.Production process be quality is loosened, can the little biomass material of force density, through the operation such as pulverizing, dry, be then processed into biomass solid particle fuel through ring mold pressing roll extrusion molding mode.The epigranular of biomass granule fuel, unit intensity can reach 1 ~ 1.4g/cm3, and intensity increases, conveniently, combustionproperty is obviously improved for transport and storage, and after burning, energy utilization rate can improve more than 80%, almost there is no sulfur dioxide emissions, the ashes after burning or the organic fertilizer of high-quality.
Plant material mainly contains Mierocrystalline cellulose, hemicellulose, lignin composition.Because lignin belongs to noncrystal, being a kind of thermal plastic high polymer material, without determining fusing point, but there is higher glass transition temperature.When temperature is 70-110 DEG C, lignin is softening and have stickiness, can by the hemicellulose in plant material, Mierocrystalline cellulose under stress compression bonded become granular fuel, lignin can play a kind of effect of binding agent.Different types of plant material, its lignin, Mierocrystalline cellulose, hemicellulose level are different.Usually, in timber, the content of lignin is 27-32% (over dry raw material), and in grass kind plant, lignin content is 14-25%.Usually the Pericarppium arachidis hypogaeae be dropped in the course of processing, rice husk, wood chip etc. all can be used as the raw material of biomass granule fuel, further across compacting, become efficient carbon source.But current biomass granule fuel exists the defect that calorific value is low, burning slagging scorification is high, be unfavorable for promoting and utilizing.
Summary of the invention
Technical problem to be solved by this invention is that providing a kind of improves the composite biomass fuel that calorific value also can reduce burning slagging scorification.
For solving the problems of the technologies described above, technical solution of the present invention is:
A kind of biomass fuel, comprises biomass charcoal powder 50-60 weight part, coal dust 10-20 weight part, accelerating agent 5-10 weight part; Described biomass charcoal powder is obtained by following methods: by agricultural crop straw drying, the pulverizing of wood materials and the 30-40wt% containing 60-70wt%, mix, compression moulding; The outside surface of described biomass fuel wraps up the polyester of one deck from biomass resource, and the predominant repeat unit of described polyester is dicarboxylic acid units and diol units; Described accelerating agent contains talcum 30-40wt%, Sulphuric acid waste residue 30-50wt%, magnesium chloride enriched bittern cake 15-20wt%, SODIUMNITRATE 3-5wt%.
Further, the moisture control of described biomass charcoal powder is at 12wt%-15wt%.
Further, the particle diameter of described biomass charcoal powder is less than 1mm.
Further, the wood chip that described wood materials is selected from wooden tankage, wooden waste products, wood working produce or its combination.
Further, described agricultural crop straw is selected from wheat stalk, maize straw, broomcorn straw, cotton stem or its combination.
Further, described coal dust is pulverized obtained by raw coal, its moisture control is at 5wt%-8wt%.
Further, the particle diameter of described coal dust is less than 1mm.
Further, the polyester thickness of described biomass resource is 20-50 micron.
Further, described biomass fuel comprises biomass charcoal powder 55 weight part, coal dust 20 weight part, accelerating agent 8 weight part.
Further, described accelerating agent contains talcum 35-40wt%, Sulphuric acid waste residue 40-45wt%.
The invention has the beneficial effects as follows: biomass energy and mineral fuel are organically combined, the biomass fuel caking ability produced is good, and fuel value is high, and Air–pollution From Combustion is little, produces sulfurous gas and flying dust hardly, is beneficial to the construction of ecotope; The biomass polyester of its outside surface parcel makes this fuel storage convenient transportation, and particle is not easily broken.In addition, owing to employing accelerating agent, can improve thermo-efficiency about 10%, reduce slag remaining carbon about 10%, make the concentration of sulfur dioxide in flue gas reduce 50-60%, in flue gas, carbon monoxide concentration reduces about 40%.
