Description

Solid-fuelled burner
Technical field
The utility model relates to solid fuel ignition field, specifically, has about the solid-fuelled burner of one.
Background technology
From fuel grade angle, solid fuel, because of aboundresources, use safety, is the most widely used a kind of incendiary material, particularly coal of modern humans.In addition, along with the increase of the demand of the mineral solids fuel taking coal as representative, the minimizing of resource, and the expansion of global new forms of energy motion, reproducible biomass combustion material, as straw, straw, timber, wood chip, deadwood etc. obtain people's great attention.
The direct ignition combustion of major way that uses at present biomass combustion material, this mode efficiency of combustion is very low, and produces a large amount of black smokes, causes environmental pollution.
All the time, a lot of people attempt to adopt existing coal stove to carry out firing biomass fuel.Because the combustion characteristics of biomass combustion material and the higher mineral matter incendiary material of fixed carbon content has larger difference, existing combustion stove can not adapt to the solid-fuelled burning being made up of reproducible biological material, cause efficiency of combustion low, there is the problems such as exhaust emission, thereby restricted the application of biomass combustion material.In addition, a large amount of coals that use are all the high-rank coal that fixed carbon content is higher, such as anthracite, bituminous coal etc. now, some grizzles, such as brown coal, mud coal etc., utilize existing burner, exist too efficiency of combustion low, the problems such as over-emitting black exhaust, are not therefore also used widely at present.
The utility model people finds after scrutinizing, biomass combustion material such as, with grizzle (brown coal, mud coal etc.) compared with high-rank coal, main difference is that the fixed carbon content very high (generally more than 90%) of high-rank coal is therefore mainly fixed carbon combustion system in the time of burning; And the fixed carbon content of biomass combustion material and grizzle is lower, and volatile content higher (probably at 50%-70%)., mainly there are two features: 1) fugitive constituent Precipitation Temperature is lower than fugitive constituent burning-point in the solid fuel that this volatile content is high; 2) burning-point of fugitive constituent is higher than ash fusion point.
Current combustion furnace is generally divided into two kinds of forward combustion stove and trans combustion furnaces, because biomass fuel and grizzle exist These characteristics, adopts these two kinds of combustion furnaces all cannot realize lasting efficient burning.
In the time adopting existing forward combustion stove burning, there are the following problems:
1) efficiency of combustion is low.In the time of burning, because the Precipitation Temperature of fugitive constituent is lower than the burning-point of fugitive constituent, first fugitive constituent is separated out and is discharged in air in the mode of black smoke, remaining fixed carbon part is burnt again, the heat that has so only utilized fixed carbon burning wherein to produce, not only efficiency of combustion is lower, and has exhaust emission.
2) can not sustained combustion.Existing burner is generally by fire grate air intake, make the solid fuel on fire grate carry out high-temp combustion, because ash fusion point is lower than the burning-point of fugitive constituent and fixed carbon, under the hot environment that fixed carbon burns on fire grate, ashes after burning are in being thick molten condition, can stick with paste on fire grate, cannot for example, normally discharge by fire grate or other ash exhauster (gray moving rod), these thick ashes are blended in the fuel burning, have greatly affected the efficiency of combustion of fuel.And these thick ashes are bonded on fire grate, stop up the air intake passage on fire grate, after a period of time, fire grate can be stuck with paste extremely, combustion furnace cannot be worked on.
The feature of trans combustion furnace is that crater, lower than fire grate, makes the flame of burning generation oppositely by arriving crater after fire grate again.This combustion system is compared with forward combustion, and the fugitive constituent of separating out can be by flame ignition when by fire grate, and efficiency of combustion is improved.But because thermal-flame is positioned at fire grate position, this also makes the temperature of fire grate position very high, under hot environment, ashes after burning are in being thick molten condition, can stick with paste on fire grate, stop up the gas channel of fire grate, fire grate will soon have been stuck with paste extremely, combustion furnace cannot be worked on.
The patent No. is that 01220213695.8 Chinese utility model patent has proposed one and can be used for the clean-burning hot-blast stove 900 of the clean-burning multiple spot air distribution of various solid combustibles being burned.As shown in Figure 2, this hot-blast stove comprises body of heater, is respectively equipped with upper combustion chamber 92 and lower combustion chamber 93 in body of heater, and the bottom of upper combustion chamber 92 and lower combustion chamber 93 is respectively equipped with upper furnace grate 94 and lower fire grate 95, the below of lower fire grate 95 is dedusting chamber 96, and the body of heater of lower combustion chamber 93 is provided with outlet flue 98.In upper combustion chamber 92, be provided with top and inboard wall of furnace body is integrated, bottom undergauge is the funnel-form combustion bin 910 of cylinder, the lower port of funnel-form Bunker 910 is positioned on upper furnace grate 94, the center of funnel-form Bunker 910 is longitudinally provided with the cylindric fireworks channel 911 of lower ending opening, between the outer wall of funnel-form Bunker 910 bottoms and the inwall of body of heater 91, be formed with annular upper air duct 912, on the outer wall of funnel-form Bunker 910 bottom cylinders, evenly offer multiple fresh air inlets 913, on the outer wall of body of heater 91, offer two air inlets that are connected with annular passage 914, air inlet 914 places are connected with air duct 915.
This hot-blast stove examination way is by being burned in conjunction with the problem that solves forward combustion and trans burning and exist, but this hot-blast stove 900 is in use, has following defect and cannot continue to use:
1) owing to separating by upper furnace grate 94 between upper combustion chamber 92 and lower combustion chamber 93, in combustion process, the interior unburnt fuel requirement of upper combustion chamber 92 drops into lower combustion chamber 93 and burns away, can not match the speed to lower combustion chamber's 93 blankings by upper furnace grate 94 if fall into the burning velocity of lower combustion chamber's 93 interior unburnt fuel, the unburnt fuel of lower combustion chamber's 93 interior heaps is more and more, after a period of time, outlet flue in lower combustion chamber 93 98 can be blocked, not only cannot burn away, and combustion gas meeting in combustion chamber is emerged from air inlet, may cause security incident.But because the burning velocity of different fuel exists difference, in actual use, being difficult to ensure that above the burning velocity of lower combustion chamber is mated completely, when being used, this hot-blast stove there is hidden danger.
2) fuel burns in upper combustion chamber 92, flame need to enter into lower combustion chamber through upper furnace grate, thereby make the temperature of upper furnace grate position still very high, on upper furnace grate, still have molten grey problem, after burning a period of time, the ashes of upper furnace grate melting are bonded together the fuel on upper furnace grate, cannot be by upper furnace grate to lower combustion chamber's blanking, fuel can only burn in upper combustion chamber, and on upper furnace grate, ashes are finally stuck with paste upper furnace grate completely, thereby causes the hot-blast stove cannot continuous firing.
3) as shown in Figure 2, this hot-blast stove is for improving efficiency of combustion, from a large amount of air distributions of lower fire grate 95 leeward of lower combustion chamber 93 bottoms, cause the excess Temperature of lower fire grate 95 positions, and the ash fusion point of some solid biomass fuels (as stalk) is lower, thereby make this hot-blast stove produce and melt grey phenomenon in the time of burning solid biomass fuel, the molten condition of ash in thickness that burning is produced, and on bonding lower fire grate 95.Like this after this hot-blast stove work a period of time, the gap of lower fire grate 95 is melted ash and is pasted over, effectively ash discharge, thus cause this hot-blast stove cannot continuous firing.
Therefore, be necessary the solid fuel combustion furnace of solid fuel (for example biomass fuel) burning that provides a kind of applicable volatile content high, overcome the above-mentioned defect that existing combustion furnace exists, realize solid-fuelled orderly controlled burning.
