Description
Technical field
The utility model relates to a kind of boiler combustion system, particularly a kind of biological fuel gas that adoptsBoiler combustion system.
Background technology
As everyone knows, the fossil energies such as coal, oil, natural gas are all non-renewable resources, peopleUnder the large-scale exploitation of class, peter out. In addition, these fuel can be arranged in the time of burning in airThe toxic and harmful of amplification quantity, causes Air seriously polluted. For this reason, energy field expert just exertsPower is found reproducible clean fuel and is replaced fossil energy.
Biomass fuel (is called for short BMF, such as agriculture and forestry organic waste material, as stalk, sawdust, sugarcaneSlag, rice chaff etc.) there is following feature: when 1, the energy of BMF comes from its growth to fromSo CO of boundary2Absorption, therefore BMF has CO2The feature of ecological " zero " discharge; 2, BMFBurning taking fugitive constituent as main, the content of its fixed carbon is 15% left and right, is typical low-carbon (LC) fuel;3, the sulfur content of BMF is also lower than diesel oil, is only 0.05%, and not needing to arrange desulfurizer just can be realExisting SO2Discharge; 4, the ash of BMF is only 1.8%, is 1/10 left and right of coal derived fuel,Simple dust arrester is set, and just to realize dust emission up to standard; 5, BMF nitrogen content is low, and oxygen containsMeasure highly, when burning, generate less NOX; 6, BMF derives from agriculture and forestry organic waste material, feed distributionExtensively various, cost is low, and cycling deposition is inexhaustible, is typical recycling economyProject.
Gasification of biomass is taking living beings as raw material, under gasifying agent effect, conventionally with oxygen (skyGas, oxygen enrichment or pure oxygen), steam or hydrogen etc. are as gasifying agent (also referred to as gasification matter), at heightUnder temperature condition, pass through thermal chemical reaction, the mistake that is combustible gas by Partial Conversion flammable in living beingsJourney. The gas componant producing when gasification of biomass mainly comprises H2、CH4With CO etc., conventionally willThis fuel gas is called biological fuel gas.
But the calorific value of biological fuel gas is low, tar content is high, if picture natural gas or coal gas thatSample is directly supplied to boiler plant and uses as fuel, and efficiency of combustion is low on the one hand, on the other hand canCan bring potential safety hazard.
As Chinese patent application discloses a kind of charcoal processing production use of being disclosed for No. 102954456AEnergy saver, comprises gasification furnace, combustion chamber and boiler plant, and combustion chamber is connected also with gasification furnaceBe positioned at boiler plant, and boiler plant also comprise pot bucket, cook bucket and be positioned at pot bucket andThe water screen tube of cooking between bucket, owing to adopting biogas as combustion gas, it is than directly using skySo gas reduces costs 40%, than using oil to reduce costs 150%. But, this charcoal processing production useThere is following shortcoming or deficiency in energy saver: the waste heat of (1), its gasification furnace body of heater is not filledDivide and utilize; (2), biological fuel gas does not pass through any filtration, purification and just uses as combustion gas, this generalBring potential safety hazard to boiler plant; (3), burner do not improve for biological fuel gas,Efficiency of combustion is low.
And for example Chinese patent application discloses a kind of gasification of biomass disclosing for No. 103499083ACombustion boiler system, comprises boiler and is used to boiler that the gasification of biomass of vaporising fuel is providedStove, biomass gasifying furnace is connected with boiler by gas pipeline, and the top of biomass gasifying furnace is provided withCharging aperture, gasification of biomass furnace interior is followed successively by air storage chamber, reative cell, storage ash bucket from top to bottom,Between reative cell and storage ash bucket, be provided with heating fire grate, charging aperture connects by a feeding pipe and reative cellLogical. But there is following shortcoming or deficiency in this biomass gasification fired boiler system: (1), itsThe waste heat of gasification furnace body of heater is not fully used; (2), adopt complicated cyclone separator andMoisture film decoking device carries out purified treatment to biological fuel gas, and system building cost is raise; (3),Burner does not improve for biological fuel gas, and efficiency of combustion is low.
Therefore, provide a kind of employing living beings that can fully improve energy utilization rate and efficiency of combustionThe boiler combustion system of combustion gas becomes urgent problem in the industry.
Summary of the invention
The purpose of this utility model is to provide a kind of boiler combustion system, and it can significantly improve biologyMatter energy utilization rate the efficiency of combustion and the security that improve boiler.
For other living beings are utilized technology, biomass gasification technology is that one extensively makesWith biomass energy transform mode. The gasification of living beings is mainly carried out in gasification furnace, byIn the type of gasification furnace, gasification reaction conditions, technological process, the kind of gasifying agent, the property of raw materialThe difference of the condition such as matter and grinding particle size, its gasification reaction process is also not quite similar. But biogasChange process substantially comprising under different condition: C+O2＝CO2；CO2+C＝2CO； H2O+C＝CO+H2Deng.
Generally speaking, the real reaction process of living beings mainly comprises four parts: (1), dryLayer, wherein living beings enter gasifier from top of gasification furnace, are heated to about 200～300 DEG C of left sidesRight back, first the moisture in biomass material be subject to thermal evaporation, and end product is dry material; (2),Pyrolytic layer, wherein living beings dry material moves down and enters pyrolytic layer from drying layer, at high temperature actionUnder, in living beings, volatile matter will be separated out in large quantities, and its operative temperature is 500～600 DEG C of left and right,After Volatile, living beings are remaining remaining charcoal only, the volatilization that wherein pyrolysis is separated outDivide and mainly comprise hydrogen, carbon monoxide, carbon dioxide, methane, tar and other hydrocarbonDeng; (3), oxide layer (being also burning zone), wherein living beings remaining charcoal only after pyrolytic layer,Now in oxide layer with the air generation vigorous reaction that is introduced into, discharge a large amount of heat simultaneouslyAmount, for the reaction in other region provides heat, in oxide layer, is characterized in that reaction rate is fast,Floor height is lower, and temperature can be up to 1000～1200 DEG C of left and right, and it is laggard that volatile matter participates in burning simultaneouslyOne step degraded; (4), reducing zone, in reducing zone, there is no oxygen, burning in oxide layer is producedCharcoal generation reduction reaction in thing and steam and reducing zone, biological hydrogen and carbon monoxide, theseGas and volatilization grade and have formed fuel gas, complete the conversion of solid biomass to gaseous fuelJourney, because reduction reaction is the endothermic reaction, temperature is now reduced to 700～900 DEG C of left and right, andIts calorific requirement is mainly derived from oxide layer.
Biomass gasification reaction mainly carries out in gasification furnace, taking updraft type fixed-bed gasification furnace asExample, biomass material is sent into from top of gasification furnace, and gasifying agent enters stove by the air inlet of bottom of furnace bodyInterior participation reaction, bottom-up the flowing of gas that reaction produces, the last combustion gas by gasification furnace topOutlet is discharged. Wherein, the course of reaction of living beings comprise successively from top to bottom drying layer, pyrolytic layer,Reducing zone, oxide layer. Its advantage is mainly: combustion gas, will when through pyrolysis zone and dry sectionItself entrained heat is passed to biomass material, for the dry and thermal decomposition of raw material, simultaneouslyReduce the temperature of combustion gas, improve the thermal efficiency of gasification furnace; Because biomass material adds from stove topEnter, therefore biological flue gas by top out time through material bed, combustion gas is had to certain filtration,Reduce the content of ashes in biological flue gas.
