Technical field
The present invention relates to a kind of fuel, the fuel combination of especially a kind of biomass and Filter Tuber For Clean Coal.
Background technique
It is increasing to the demand of the energy with the development of economy.Due to largely using fossil energy, atmosphere is caused
Serious pollution.Biomass energy is the form of energy that solar energy is stored in biomass in the form of chemical energy, and biomass is waved with height
Hair point, low N, S content, the characteristic of low ash part.Its combustion process has CO2The characteristics of zero-emission, part, which is used as, at present is used as life
Substance boiler uses.But biomass molding fuel calorific value is lower, and generally in 3000 kilocalories --- 4000 kilocalories；Containing higher
Alkali metal oxide and salt when biomass being carried out boiler dedicated direct combustion merely, be easy to cause burner hearth dust stratification to be sintered, and to pot
Furnace body causes to corrode；Effect is less desirable.Therefore, study a kind of calorific value be not only able to satisfy boiler use, disposal of pollutants but also energy
Meet the biomass of discharge standard and the fuel combination of Filter Tuber For Clean Coal, is the current technical issues that need to address.
Summary of the invention
Boiler use, disposal of pollutants be not only able to satisfy technical problem to be solved by the invention is to provide a kind of calorific value but also can have been accorded with
Close the biomass of discharge standard and the fuel combination of Filter Tuber For Clean Coal.
The present invention the technical solution to solve the technical problem is that:
A kind of fuel combination of biomass and Filter Tuber For Clean Coal, raw material composition are as follows: biomass powder 40~50%, Filter Tuber For Clean Coal 40~50%,
Calcium lignosulfonate 5~10%；Its processing method are as follows: by granularity the ㎝ of 0.1 ㎝~0.5 powdered biomass, granularity be 50~100
Mesh cleaning coal dust and lignin sulfonic acid calcium powder, it is uniform to put stirrer for mixing into proportion, squeezes into biomass forming machine
Shaped granule, grain density are 1.1~1.3t/m3, and granularity is 0.6~1.0.
As a preferred solution of the present invention, the biomass is farming draft by-product and the woody by-product of forestry；Institute
The farming draft by-product stated is one or more of corn stover, Wheat Straw, broomcorn straw, cotton stalk and sunflower pole；It is described
The woody by-product of forestry be bark, tree root, branch, wood leftover material and sawdust.
As a preferred solution of the present invention, the Filter Tuber For Clean Coal is low-sulfur, low ash, high-carbon, high volatilization, high heating value
Cleaned coal or high-purity high-quality coal Jing Guo dressing of coal by washing.
As a preferred solution of the present invention, the calcium lignosulfonate (abbreviation calcium lignosulfonate) is a kind of multicomponent high score
Sub- polymer anion surfactant, appearance be it is light yellow to dark brown powder, slightly aromatic odor, molecular weight generally exists
Between 800~10000, there is very strong dispersibility, caking property, sequestering.Usually from acid polishing (or be sulphite
Method slurrying) cooking waste liquor, it is spray-dried to form.Contain up to 30% reduced sugar.It is dissolved in water, but insoluble in any general
Logical organic solvent.The pH value of its 1% aqueous solution about 4~6.
Forming principle: contain certain cellulose and lignin in biomass, lignin is the structure list in biomass
Body is stupid propane high-molecular compound；Have the function of enhancing cell wall, cellulose-binding.Lignin belongs to noncrystal, normal
The lower major part of temperature does not dissolve in any solvent, without fusing point, but has softening point.When temperature reaches certain value, lignin softening
Bonding force increases, and under the action of certain force, makes the dislocation of its fiber molecule group, deformation, extends, internal adjacent biologic grain
It mutually carries out bridle joint, reconfigure and compression moulding.After mixing Filter Tuber For Clean Coal, lignin adhesion strength weakens, calcium lignosulfonate
Cooking waste liquor from acid polishing, the lignin of Gao Han 55% have very strong dispersibility, bonding containing 30% reduced sugar
Property, it is sequestering, therefore a certain proportion of calcium lignosulfonate is added, can increase biomass, Filter Tuber For Clean Coal mixed-forming fuel it is viscous
Knot property, increases the finish of shaped fuel, prevents shaped fuel surface checking.Meanwhile calcium lignosulfonate is to subtract well again
Aqua reduces the usage amount of water during mixing, reduces the water content of shaped fuel, and drying time shortens.It
Dispersibility so that fuel combination is burnt in combustion more sufficiently, reduce flue dust and formed, and the aromatic odor that volatilizees.
Biomass of the present invention and Filter Tuber For Clean Coal different proportion mixed-forming fuel, take three parts of each 25kg, with Small Civil biology
Matter warming stove vulcanization bed combustion experiment, comprehensive data analysis are concluded that
1. influence of the mixed combustion to boiler output power: biomass and the combustion process of coal for mixing combustion are divided into two combustion phases, due to
The Volatile temperature of biomass will be far below the Volatile temperature of Filter Tuber For Clean Coal, mix heat release of the combustion for coal combustion early period
There is enhancement effect, coal ignition is promoted to shift to an earlier date.Combustion-supporting with biomass, the flammability of coal obtains different degrees of change
It is kind.It is mixed and burned maximum rate to be slowed down than single fire biomass, corresponding temperature has the tendency that moving back, and maximum combustion intensity is also fast
Speed increases, and fire box temperature significantly increases.In the constant situation of boiler electric controller gear, mixes and fire fuel, year-on-year single fire biomass,
Unit time consumption reduces by 40%.Since the calorific value of Filter Tuber For Clean Coal is higher than biomass, as hearth combustion intensity increases, boiler
Heating surface area is increase accordingly, and radiant power is obviously reinforced.
2. influence of the mixed combustion to SO2 emission performance: since most of biomass sulfur content is few or not sulfur-bearing, mixing combustion
It can be effectively reduced the discharge amount of SO2.It is nitrogenous, sulphur is lower, the higher biomass of volatile matter, the effect for reducing pollutant is more aobvious
It writes.This is because contain content of volatiles in biomass fuel, the oxygen at initial stage of burning mainly for biomass volatile combustion,
To making to form oxygen-depleted zone during biomass and coal multifuel combustion, limit the intermediate product of fuel N in coal to the conversion of NOx and
The formation of SO2；Biomass itself has certain lignin and humic acid simultaneously, they have huge specific surface area, simultaneously
There is stronger adsorption capacity to SO2, has delayed the speed of separating out of SO2, increased reaction surface；In addition, biomass fuel contains
Relatively large number of K, Ca, Na active constituent, can promote the formation of solid sulfate salt, such as CaSO4, K2SO4, Na2SO4 etc.,
To reduce pollutant emission.
3. influence of the mixed combustion to NOx emission characteristic: the nitrogen-containing pollutant generated in combustion process mainly has NO, NO2, N2O
Deng further including the nitrogenous intermediate product such as HCN, NH3.Its type generated and production quantity and fuel type, ignition temperature and combustion
It is closely related to burn region excess air coefficient etc..The main reason for biomass and coal for mixing combustion can reduce the concentration of emission of NOx is such as
Under:
(1) biomass contains a large amount of volatile matters, is precipitated and then burns rapidly at low temperature, and biomass volatile matter and coal rob oxygen combustion
It burns, thus formed compared with low oxygen concentration, and the formation of NOx is depending on reducing substances in the oxidation process and bed of nitrogen in fuel in bed
(such as coke and HCN, NH3 nitrogen substance) to the balance between the reduction decomposition process of NOx, when excess air coefficient is low in bed
When, be conducive to the reduction decomposition reaction of NOx；
(2) biomass N content itself is far below coal, thus plays " dilution " to overall NO conversion ratio.Biomass and coal simultaneously
It influences each other in combustion, there is significantly collaboration to reduce NO discharge effect at 800~900 DEG C；
(3) containing a certain amount of HCN and NH3 in the volatile components that biomass releases, NH3 can resolve into NH2 and NH, it
NO can be reduced into N2, thus play the role of reduce NOx；And HCN can resolve into NCO under the action of O2, it is further
Pollutant N2O can be generated by reacting with NO.But mixed combustion to reduce the effect of NOx in combustion process with the leaded wastewater of biomass itself,
The difference of coal (ash component) and difference occurs；
(4) biomass belongs to fibre structure, and a large amount of porous cokes are formed after Volatile, promotes NOx and coke
Reduction reaction.Chemical equation is as follows:
NO+(-C)→N2+(-CO)
NO+CH2→N2+H2CO
But the addition of biomass reduces the effect for reducing NOx with the raising of temperature, it is likely to because of one side high temperature
Under heating power NOx yield increase；Another aspect biomass burning point is low, and temperature is higher, and residual volatiles are fewer, volatilizees in this way
Dividing the substance of release just reduces the reduction of NOx.
4. influence of the mixed combustion to dust deposition and corrosion:
Biomass typically contains higher alkali metal oxide and salt, when biomass being carried out fluidized bed combustion merely, is easy
Cause the serious sintering of bed material particle.The reason is that following react can occur with SiO2 for alkali metal oxide and salt:
2SiO2+Na2CO3→Na2O·2SiO2+CO2
4SiO2+K2CO3→K2O·4SiO2+CO2
Studies have shown that most alkali metal salts that biomass is formed in combustion will not be taken away by flue gas, but precipitate
It is formed by ash after combustion.The fusing point of these alkali metal salts itself is lower, and when a variety of alkali metal salts (K2SO4,
K2CO3, KCl, Na2SO4) with alkali salt (CaSO4, MgSO4) coexist when, the lower eutectic of fusing point will be formed.And coal
Ash belongs to aluminosilicate, and wherein the slag making constituent content such as Fe, Ca, K and Mg is relatively low, it is difficult to melt, have lower slagging
Tend to corrosion.Sawdust, straw ash are by quartz and simple inorganic matter (such as Fe, Ca, Mg and Na) and S, phosphate and Cl group
At fusing point is lower, and slagging, fouling and corrosion with higher tend to.The chemical component of timber ash in many aspects with straw ash
It is similar, but SiO2, CaO and P2O5 content have relatively big difference.
Influence biomass ash deposition factor can be divided into factor (thermophoresis and inertial impaction) related with solid particle and with
The related factor of gas (condensation and chemical reaction).Thermophoresis is due to driving ash particles from high temperature there are temperature gradient in furnace
Area is moved to low-temperature space, this particle to diameter less than 10 μm is particularly important.
10 μm of particle is greater than for diameter, inertia force is an important factor for causing soot particle to convey to the wall surface of heating surface,
When air-flow containing soot particle turns to, the soot particle with larger moment of inertia leaves air-flow and strikes on the wall surface of heating surface.Condensation
Refer in flame with chemical reaction, inorganic matter component is in excessive temperature state in fuel, and many inorganic matters react, so
It is condensate in the form of sulfate or chloride on the wall surface of fly ash granule and heating surface afterwards, so that dust stratification layer be made to thicken.
Corn stover and bone coal fluidized bed multifuel combustion the result shows that: bone coal ash can be in biomass fluidization combustion process
In effectively inhibit the generation that fluidized bed material coheres phenomenon；Because the Al and Fe in bone coal ash can be with the alkali in biomass ash
Metallic compound and low melting point eutectic occur chemical reaction and generate high-melting-point substances, and be covered on biomass carbon particle with
Quartz sand particle surface forms isolation layer, to prevent the generation and migration of low melting point.
5. the Economic Evaluation of biomass and coal for mixing combustion:
Biomass and the economy of coal for mixing combustion are primarily referred to as burning cost, social benefit etc..Mixed combustion both solves biomass
Coking improves fuel value to boiler corrosion, reduces the discharge of greenhouse gases, is killing three birds with one stone.In current environmental protection
In the case that situation is increasingly serious, coal changes that gas, not change electrical engineering huge, and supply can not be popularized and met in the short time.In addition
Power generation is the largest pollution sources, his coal-fired thermal efficiency only has 70%, is warmed oneself again with coal power generation, the thermal efficiency=36.23%, it is clear that
Herein with cleaning electricity=other side combustion pollution coal.
Compared with prior art, it is complementary with the big energy defect of coal two that biomass may be implemented in the present invention.It is upright to biology
The calorific value of combustion is insufficient, burning coking etching problem is eased；Biomass dilutes and shadow coal noxious gas emission
It rings.So, agriculture and forestry organic waste material has obtained resource utilization, and the clean utilization of coal reduces pollutant and greenhouse gases
Discharge is a kind of inexpensive, efficient new energy application practice.Standard is executed according to national boiler air pollution emission,
Biomass is with coal mixing fuel burning and exhausting through detecting: 29 ㎎ of particulate matter/m3 in its burning waste gas, 50 ㎎ of sulfur dioxide/m3, nitrogen
210 ㎎ of oxide/m3, flue gas blackness≤1, particle concentration are slightly above natural gas, are lower than coal and fuel oil, and sulfur dioxide meets
Natural gas discharge standard, nitrogen oxides are slightly above natural gas, are lower than coal and fuel oil.Conclusion: meet national emission standard.
