Description
Technical field
The invention belongs to biomass combustion fields, in particular to a kind of efficiently to utilize biological resource system and its production work
Skill.
Background technique
Biomass energy is world's fourth largest energy, is only second to coal, oil and natural gas.In face of pair of resource and environment
The drawbacks of weight power, electric structure of the China based on coal electricity will gradually show it, greatly developing renewable energy is to solve me
One of the most viable scheme of the current energy and environment of state.Reasonable development and utilize biomass energy, improve China's energy resource structure,
It is in response to national energy conservation and emission reduction policy, breaks through the main path that environment restricts socio-economic development.Biomass Energy Development,
Substitute the resources such as traditional coal, petroleum, natural gas, additionally it is possible to the discharge of carbon dioxide and sulfur dioxide is substantially reduced, it is right
Environment generates huge benefit.
Directly burning is that biomass is most direct, one of most effective Land use systems to biomass in the boiler, but with biology
Matter heat supply and the construction of biomass power plant and operation, some quite unexpected combustion process problems, raw material are collected storage and are asked
Topic starts a degree of to constrain the normal operation of generating equipment, wherein coking and dust stratification during biomass combustion with
And corrosion phenomenon is the problem of influencing the most serious that boiler operates normally.
Defect existing for biomass combustion is illustrated below:
1, biomass combustion specificity analysis
Coking and dust stratification and etching problem during biomass combustion mainly form spy by the element of biomass fuel
Property determine.It is well known that the basic chemical element for including in biomass has carbon, hydrogen, oxygen, nitrogen, potassium, sodium and microelement such as:
Magnesium, calcium, aluminium etc..Wherein the main distinction of biomass fuel and coal is that alkali metal element content is higher in biomass, in general coal
Alkali metal content is in 0.1~0.5 % or so, and alkali metal content can be up to 3% in biomass, in addition, there is also sulphur for biomass
Content is low (content is generally less than 0.12%), and chlorinity is higher (0.01%~0.7%), chlorine usually with the alkali metal such as potassium, sodium
Exist in the form of villaumite.In terms of ash composition, biomass ash generally have SiO2, A12O3, MgO, K2O, Na2O, Fe2O3,
CaO, P2O5, TiO2 etc., a portion be fuel inherently, by being formed in plant Natural growth process, and equably
It is distributed in fuel, another part is brought into the process for fuel post-production, such as soil, grains of sand etc..Alkali metal and chlorine,
The elements such as sulphur and all kinds of inorganic salts are mainly reflected in biomass combustion using the influence that process generates: first is that burned
Cheng Zhong, the alkali metal contained in biomass exist in the form of liquid molten, these liquid molten objects are easy and biomass
The bondings such as grain, grey solid impurity particle are agglomerating, lead to the positions coking such as fire grate, burner hearth, influence the combustion process of normal table in furnace；Two
It is that the alkali metal contained in biomass is precipitated in the form of a vapor, such as KCl (g), KOH (g) etc., these gaseous products are in high temperature
It is cooled on heat exchanger surface, forms sticky molten state substance and be adhered on heating surface, and continue to trap the solid in flue gas
Particle forms reunion and slagging, influences heating surface heat transfer effect, equipment thermal efficiency is caused to reduce；Third is that combustion process discharges
KOH (g), NaOH (g), the gases such as HCl, SO2 burner hearth refractory material, heat exchanger metal surface are caused to corrode, reduce equipment
Service life.
By influence of the analysis alkali metal to biomass combustion process, coking and dust stratification during biomass combustion with
And the mechanism of corrosion mainly has following three types: the first kind, is alkali metal silicate salt form, i.e. silicon reacts with alkali metal and causes
Coking.Silicon mainly exists in plant with aquation indefiniteness silica and quartz, and potassium is most important in biomass
Alkali metal element；Silicon and potassium just can form the eutectic of molten condition at a lower temperature in combustion, cause fire grate with
The positions coking such as burner hearth.Second class is alkali metal compound type, the i.e. inorganic potassium salt of the formation such as alkali metal and oxygen, chlorine, carbon and sulphur
Caused slagging.In combustion high temperature area, alkali metal compound gaseous oxide, chloride, sulfate and hydrogen-oxygen easy to form
Compound etc., and being present in flue gas, when reach be cooled around heating surface when, be set on heating surface metal surface, go forward side by side one
Step sticks the flying dust in flue gas and forms dust stratification.Third class is low temperature eutectic fusion.The fusing point of KCl itself is 774 DEG C, but is worked as
In the presence of KCl and FeCl2 are common, can form its fusing point of low temperature eutectic body is 355 DEG C；The eutectic that KCl and CrCl2 is formed is molten
Point is 470 DEG C；The eutectic bulk melting point that KCl and FeCl3 is formed only has 202~220 DEG C.Therefore alkali metal chloride can be with heat exchange
Metal or metal oxide on device surface react, and local liquid phase is formed in metal surface.Due to chemical reaction
The characteristics of speed ratio consolidates solid phase reaction faster in the liquid phase, this molten state substance can increase the rate of corrosion.
2, biomass combustion equipment status
The utilization history of biomass resource is very long, and in biomass combustion technical aspect, what is be most widely used is main
There are Direct-Combustion Technology and pyrolytic gasification technology two major classes, wherein Direct-Combustion Technology application is the most universal.Direct fired technology root
Dividing according to the pattern of fire grate just has the multiple types such as fixed grate fire, reciprocating grate furnace, chain furnace, rotary fire grate, exists from material
Form in furnace is distinguished, and there are also a variety of patterns such as layer burner, suspension bed, bubbling bed, fluidized bed.But due to biomass object
Expect that most existing forms are irregular, the parameter fluctuations range such as particle diameter distribution, density, specific surface area and moisture content is big, material
The poor defect of uniformity is accumulated, no matter the combustion apparatus of which kind of pattern is easy to hair in the direct combustion process of biomass
Raw incomplete combustion and part generate the situations such as high temperature burning.Incomplete combustion causes using energy source insufficient, under economy
Drop；And localized hyperthermia then be easy because more than biomass material ash fusion point, thus cause the coking in combustion apparatus, dust stratification with
And the problems such as corrosion.The problems such as coking, dust stratification and corrosion occur during biomass combustion is the burning due to material itself
What characteristic determined, it, can not be from root by the structural shape of change combustion apparatus come the non-uniform characteristic of adapted biomass material
It is solved the problems, such as on this.Therefore, biomass pyrogenation gasification technology is come into being, and biomass pyrogenation gasification technology is directly to burn
A kind of more clean and environmental protection and efficient combustion technology developed in technical foundation, utilizes anoxycausis and high temperature
The principles such as thermal cracking convert biomass into fuel gas, and obtain clean combustion gas by various purification means.
The temperature as used in pyrolytic gasification technology is generally below 700 DEG C, be generally in biomass ash fusion point hereinafter,
And since pyrolytic gasification technology is mainly to be theoretically it is possible to prevente effectively from direct fired technology using for the purpose of clean gas
The problems such as boiler plant coking of generation, dust stratification.But since pyrolytic gasification technology development time is limited, technology is still immature,
At present using it is more be still based on fixed bed, and it is uneven still to can't steer clear of biomass in fixed-bed pyrolysis gasification
Characteristic, in addition the non-uniform joint effect of cloth wind in furnace, still can there is a phenomenon where cokings in gasification furnace, seriously affect gas
Change the operational reliability of furnace.Although fluidized-bed gasification furnace has uniform mass-and heat-transfer process, but be limited by gasification dosage and
Biomass volatile matter is high, and the material characteristic variation characteristics such as greatly are especially easy to appearance dead bed during load fluctuation, from
And the phenomenon that causing slagging, therefore, the fluidized-bed gasification furnace Engineering Projects for capableing of successful operation at present is few.In addition, by
The temperature used in biomass pyrogenation gasification is usually at 700 DEG C hereinafter, can contain a great deal of in clinker after pyrolytic gasification
Fixation carbon component, still have compared with high heating value, therefore, the gasification efficiency of pyrolytic gasification technology is not usually high, in biology
There is also larger gaps for matter efficiency of heating- utilization aspect and direct fired technology.
3, biomass anti-coking combustion technology status
The problems such as in order to solve coking during biomass combustion, dust stratification and corrosion, in biomass resource utilization skill
Occur a large amount of anti-coking combustion technologies in the development process of art in succession, such as: washing process, anti-coking agent technique, low temperature combustion
It burns, increase ash disposal and broken coke installation etc..Washing process: mainly according to biomass institute alkali metal containing generally with solubility salt
Pattern there are the characteristics of, biomass is impregnated and is washed first with a large amount of water, dissolves contained alkali gold in biomass body
Belong to salt, then large quantity of moisture is removed by the techniques such as dehydration, dry again, to obtain the lower biomass of alkali metal content
Material.Preferable effect can be usually obtained using this method, but since dehydration and drying equipment energy consumption are relatively high, is also generated
A large amount of waste water, therefore do not obtain and effectively promote.Anti-coking agent technique: mainly by adding the anti-coking agent of special development,
It improves biomass ash fusion point or improves the modes such as flying dust viscosity, asked to effectively solve slagging, dust stratification and corrosion etc.
Topic.Common anti-coking agent main component be usually dolomite, lime, bentonite, kaolin, diatomite with and combinations thereof match
Side etc., but since the agent of the type anti-coking with reacting for biomass belongs to solid-solid reaction, reaction process is extremely limited, in addition by
Larger in the treating capacity of biomass, anti-coking agent consumption occupies no small operating cost, and therefore, anti-coking agent technique is also simultaneously
Wider application and development are not possessed.Low-temperature burning technique: mainly pass through various high temperature resistant sensors, accurate control burning
Ignition temperature, burning in equipment in each region match air quantity (excess air factor), make burning temperature of the biomass material in furnace
Degree remains at ash fusion point or less.Under the premise of ensuring each normal operation of sensor, which can actually be solved effectively
The certainly coking of biomass combustion process and dust stratification problem, but lower ignition temperature brings the heat transfer temperature difference of boiler plant to reduce,
Boiler heating surface area is significantly increased, and boiler steel dosage rises, increased costs, and boiler efficiency reduces, and economy is poor.
Ash disposal and broken coke installation: the problem of setting on fire grate forces broken coke installation to can effectively solve fire grate coking, but broken coke installation
It is high to its material requirements, and operation energy consumption is high, serious wear, equipment cost and operation and maintenance cost increase, and undesirable.
Further, since alkali metal mainly exists in the high temperature environment with the pattern of gaseous metal steam, high-temperature surface surface is attached to
When viscosity it is larger, also there is higher hardness, either steam soot blowing, shock wave ash disposal, mechanical vibrator when reaching certain ulking thickness
Or mechanical forced ash disposal, can only play certain retarding action, the effect is unsatisfactory.
With on the earth fossil fuel bring environmental problem become increasingly conspicuous and fossil fuel it is increasingly depleted, it is novel
Clean energy resource substitution conventional fossil fuel seems particularly significant.Biomass energy is huge with its as a kind of excellent renewable energy
Big amount of storage and the advantages such as " low-sulfur ", " zero carbon emission ", possesses huge social value and wide application prospect.Therefore,
A reliable and stable biomass combustion novel technique is developed, for solving the main bottle during biomass resource utilization
Neck problem, necessity are self-evident.
