Description
Technical field
The device that glows of the powdered carbon fast low temperature burning of biomass molding fuel burning device, belongs to biomass fuel burning technology
Field.
Background technology
Stalk accounts for the 70% of China's biomass energy, and it is that China's biomass are applicable to clean reliable straw burning technology
It is crucial.Containing elements such as substantial amounts of potassium, sodium, chlorine in the biomass fuels such as stalk, if solid-state temperature is high during burning, particularly surpass
When crossing 800 DEG C, during especially more than 800 DEG C, these elements can volatilize, soften.The potassium of volatilization, sodium, chlorine compound part meeting
Heat exchanger surface condensation in burner hearth, pickup is formed, another part can form aerosol with fume emission to air.Bottom
The potassium sodium compound softened in ash can form slag, cause coking, the slagging scorification of fuel, cause the imperfect combustion of solid, be formed
Substantial amounts of solid slag, not only influences the reliability of burning, also causes lime-ash fertilizer to fail, it is impossible to as farmland fertilizer application.
Therefore, the high-temp combustion of stalk not only cause equipment contamination, bottom ash coking, smoke-exhaust pipeline blocking, gas-solid pollution problem, can also shadow
Circulation of the straw ash nutrient in Agro-ecological System is rung, causes soil depletion to deteriorate.
To solve these problems, the patent of Application No. 201210027287.8 discloses a kind of by MgO, the composition such as kaolin
Anti-coking agent and preparation method thereof.The patent of Application No. 201210161528.8 discloses one kind according to convection pass pressure
Difference, starts push rod and drives flexible pipe, the method for the interior dust that cleans flues.The patent of Application No. 201410216375.1 discloses one
Plant on chain furnace, biomass boiler dregs breaking device being constituted by dregs breaking tooth and cooling water pipe.These technology and equipments are improved
The reliability of biomass combustion equipment, but not from source problem.Want to be solved from root the coking of burning such as stalk,
Clogging problems, it is necessary to when reducing burning solid phase fuel temperature.The patent of Application No. 201210533851.3 is disclosed and carried
Charcoal glows the biomass boiler Efficient segmentation control combustion method and system in pond, it is desirable to which charcoal smoldering temperature is 400 DEG C ~ 600 DEG C, though
The temperature of charcoal burning is so given, but does not provide method or the measure of specific control ignition temperature.
During biomass combustion, when early stage is dried and is pyrolyzed, due to endothermic effect, solid fuel self-temperature is not
It is high.To charcoal combustion phases, due to the hot environment of violent exothermic effect and burner hearth, fuel solids portion temperature can be made drastically to rise
Height, accordingly solid-state temperature when controlling charcoal to burn.Accumulation is glowed and the burning of charcoal fine particle can be made to maintain low temperature
State, and the ash that glows is without any coking, slagging scorification phenomenon.（Referring to paper：1st, He Fang, Frank Behrendt, Experimental

In 1 gas phase high temperature combustion zone, and the temperature of gas that pond of glowing goes out in gas tank 28 is not less than 300 DEG C.
Step（4）, ash content discharges after cooling.
Ash content is into cooler bin 32 and is deposited in cooler bin 32, and is changed with the air in heat exchanger tube 39 by heat exchanger tube 39
Heat, so as to be cooled down to ash content, less than 80 DEG C is cooled to by the temperature of ash content, and the ash content after cooling is conveyed through exporting auger 6,
And discharged by ash hole 5, the gas in heat exchanger tube 39 is delivered to the gas phase high temperature combustion zone in burner hearth 1 through cooler bin escaping pipe 34
It is interior.Through cooler bin escaping pipe 34 into the gas in burner hearth 1 after being exchanged heat with ash content, temperature is not less than 300 DEG C.
Biomass fuel is dried and is pyrolyzed in burner hearth, is fallen into immediately after the completion of pyrolysis in pond 20 of glowing and glowed, and is glowed
Temperature is 400 DEG C ~ 650 DEG C, and referred to as solid-phase low-temperature glows；Dry and the gas of pyrolysis generation burns in gas phase high-temperature region, by
In by glow pond escaping pipe 29 and cooler bin escaping pipe 34 be passed through the top of burner hearth 1 gas temperature higher than 300 DEG C, therefore gas
The temperature of burning is very high, usually above 900 DEG C, referred to as gas phase high-temp combustion.
