Abstract
The invention relates to the field biological energy sources, in particular to anti-sintering biomass fuel. The anti-sintering biomass fuel comprises the following ingredients in parts by weight: 25-50 parts of stalk, 15-25 parts of straw, 5-10 parts of walnut shell, 5-13 parts of bark and 0.5-2 parts of anti-sintering agent, wherein a molecular formula of the anti-sintering agent is C25H19O4N3Zn. Compared with the conventional biomass fuel particles compressed by the stalk, the biomass fuel has a low water content, a high combustion value and long combustion time, and can be converted into acidic oxide in situ by adding the anti-sintering agent; properties of the biomass fuel particles can be effectively adjusted; the biomass fuel particles have low possibility of slagging; and no harmful gas is emitted after combustion of the biomass fuel particles.
Description
Technical field
The present invention relates to field of biological energy source, be specifically related to a kind of anti-sintered type biomass fuel.
Background technology
Agriculture and forestry organic waste material, if stalk, sawdust, bagasse, rice chaff etc. are green energy resources as biomass fuel, the fuel that national policy is encouraged, there is following characteristic: the total carbon dioxide capacity that the carbonic acid gas absorbed by photosynthesis in biomass growth process and its burning are discharged is suitable, from the angle of life cycle, biomass combustion release of carbon dioxide, does not bring the increase of carbon dioxide content in air.Therefore, according to national agreement, this part carbonic acid gas is not as greenhouse gases process.
But in biomass combustion process, because biomass contain more moisture and basic metal material (especially agricultural crop straw), easily cause fouling and slagging to damage burning bed during burning, also sintering phenomenon may occur.Alkali metal content (K, Na) high in biomass causes the ash fusion point of biomass lower, brings many problems to combustion processes.Utilize in process in burning, high alkali metal content is the important factor causing boiler surface dust stratification, slagging scorification and corrosion, can directly cause boiler life and thermo-efficiency reduction etc.; Simultaneously high alkali metal content also easily causes the agglomerate of bed material, slagging scorification destroys fluidisation in bed, and combustion conditions is worsened.
Summary of the invention
It is high that technical problem to be solved by this invention is to provide a kind of fuel value, and a kind of biomass fuel of anti-sintering.
Technical problem to be solved by this invention is achieved by the following technical programs:
A kind of anti-sintered type biomass fuel, is made up of the component of following parts by weight:

The present invention has following beneficial effect:
Biomass of the present invention are compared with the biomass fuel pellet using straw compressing and forming of routine, biomass fuel water ratio of the present invention is low, fuel value is high, combustion time is long, acidic oxide can be changed into by in-situ transesterification by the antiwelding agent added, can effectively regulate biomass fuel pellet character, make its not easily slagging scorification, and there is no the discharge of obnoxious flavour after the burning of this biomass fuel pellet.
Embodiment
Below in conjunction with embodiment, the present invention will be described in detail, and embodiment is only the preferred embodiment of the present invention, is not limitation of the invention.
Antiwelding agent of the present invention if no special instructions, is prepared all as follows.
By 0.1 mmol4,4'-(methyl azane two base) dibenzoic acid (4,4'-(methylazanediyl) dibenzoic acid), 0.1 mmol4, the zinc nitrate of 4-dipyridyl and 0.2 mmol is dissolved in the middle of the mixed solvent of 10 mL water and 5 mL dimethyl formamides, at room temperature stir and form mixed liquor A, be 7.5 with mineral alkali by the pH regulator of mixed liquor A, then above-mentioned mixed liquor A being refluxed at 80 DEG C obtains mixed liquid B in 6 hours.
Then described mixed liquid B to be inserted in 25 mL hydrothermal reaction kettles reacting by heating under solvent thermal 140 DEG C of conditions to be down to room temperature with 5 DEG C/h after 48 hours and to obtain described antiwelding agent.
Then antiwelding agent is carried out structural characterization.
The X ray diffracting data of this antiwelding agent visits on diffractometer in Bruker Smart Apex CCD face, uses MoK
αradiation (λ=0.71073), collects with ω scan mode and carries out Lp factor correction, and absorption correction uses SADABS program.Use direct method solution structure, then obtain whole non-hydrogen atom coordinate by difference Fourier method, and obtain hydrogen atom position (C H 1.083) with theoretical hydrogenation method, by method of least squares, structure is revised.Evaluation work completes with SHELXTL routine package on PC.
Resolve known after tested, this antiwelding agent chemical molecular formula is C
