Abstract
The utility model discloses a low-temperature low-ash double-stage charcoal combustor. The combustor comprises a combustion chamber provided with a material inlet, a residue discharge outlet, air inlets, and an exhaust outlet; an interlayer air passage arranged in the outer wall of the combustion chamber and communicated with a primary air inlet; and a semi-partition board arranged in the combustion chamber for dividing it into a gasification reaction chamber and an exhaust flue, which are communicated via a space above the semi-partition board. The air outlet of the interlayer air passage includes multiple air distribution ports uniformly distributed on the lower sidewall of the gasification reaction chamber. The exhaust outlet is an interlayer tube arranged on the sidewall of the combustion chamber close to the exhaust flue and extending outwards, a secondary air inlet is arranged on the interlayer tube, and multiple flow guide grooves communicated with the tube cavity are formed on the inner wall of the interlayer tube along tangential direction. The utility model regulates primary/secondary air ratio to realize double-stage controlled combustion, realize low-temperature gasification and combustion, and greatly reduce discharge of nitrogen oxides and smoke.
Description
Technical field
The utility model relates to burner, especially relates to the low grey two-stage combustion device of charcoal low temperature.
Background technology
Burner is to be used for the novel burner of solid fuel with low temperature gasification burning and secondary completing combustion mode fed oil burning boiler to substitute fuel combustion with the high-temperature gas that produces, and reaches and reduces oil burning boiler operating cost purpose.Being used for the existing deficiency of above-mentioned purpose burner at present mainly shows as: for improving burning, solid fuel in vaporescence ignition temperature generally more than 950 ℃, this nitrogen oxide that just makes charcoal be generated when gasification, and combustion is too high, the needed air capacity of gasification, and combustion is bigger simultaneously, but the burning fume rate of flow of fluid height that is produced, so the dust emission that flue gas is taken out of is many, causes severe contamination to environment.
The utility model content
The purpose of this utility model is to provide a kind of low grey two-stage combustion device of charcoal low temperature that is used for the charcoal clean combustion.
For achieving the above object, the utility model can be taked following technical proposals:
Charcoal low temperature described in the utility model hangs down grey two-stage combustion device, and it comprises the combustion chamber that is provided with charging aperture, slag-drip opening, air inlet and exhaust outlet, and described outer wall of combustion chamber is the interlayer air channel structure; Described interlayer air channel communicates with an air inlet; Be provided with semiclapboard in the combustion chamber it is divided into gasification reactor chamber and exhaust uptake, described gasification reactor chamber and exhaust uptake communicate by the space of semiclapboard top; The air outlet in interlayer air channel is the uniform a plurality of cloth air port that is opened on the described gasification reactor chamber lower sides; Described exhaust outlet offers the secondary air mouth for being set in place outward extending interlayer tube on described discharge flue one side combusion chamber's sidewall on described interlayer tube; Tangentially offer many guiding gutters that are connected with its chamber at interlayer tube inwall.
On described sidewall of combustion chamber, offer the temperature survey hole.
Described gasification reactor chamber bottom offers the funnel shaped of two lateral walls for extending to described slag notch direction in a plurality of cloth air port.
Advantage of the present utility model is to realize twin-stage control burning by regulating the primary and secondary air ratio.During work, burn at 600-950 ℃ of scope low temperature gasification, realize the low temperature gasification burning, greatly reduce nitrogen oxide and generate by regulating an intake control of burning charcoal.By regulating burning secondary air amount, many guiding gutters that secondary air is offered along described interlayer tube inwall tangential direction enter the interlayer tube inner chamber, form tangential rotary combustion wind and fully burn with the gasification flue gas, but make burning fume realize completing combustion.The low temperature gasification needed air capacity of burning accounts for the 40-60% of total air, and the little speed of flammable flue gas volume that is produced is low, has only the 25-40% of normal combustion, realizes the original discharging of micro-exhaust gas dust thus.The setting of described semiclapboard is divided into gasification reactor chamber and exhaust uptake with the combustion chamber, so exhaust outlet position flexible arrangement as required, greatly facilitates the installation at air feed scene.It is little to the utlity model has volume simultaneously, and characteristic of simple structure is that charcoal replaces the ideal burning equipment of fuel oil at high price at a low price.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is that the A-A of Fig. 1 is to cutaway view.
Fig. 3 is that the B-B of Fig. 1 is to cutaway view.
The specific embodiment
As shown in the figure, charcoal low temperature described in the utility model hangs down grey two-stage combustion device, and it comprises the combustion chamber 3 that is provided with charging aperture 1, slag-drip opening 2, air inlet and exhaust outlet, and described combustion chamber 3 outer walls are interlayer air channel 4 structures; Described interlayer air channel 4 communicates with an air inlet 5; Be provided with semiclapboard 6 in combustion chamber 3 it is divided into gasification reactor chamber 7 and exhaust uptake 8, described gasification reactor chamber 7 and exhaust uptake 8 communicate by the space of semiclapboard 6 tops; The air outlet in interlayer air channel 4 is the uniform a plurality of cloth air port 9 that is opened on described gasification reactor chamber 7 lower sides; Described exhaust outlet offers secondary air mouth 11 for being set in place outward extending interlayer tube 10 on described discharge flue 8 one side combusion chambers 3 sidewalls on described interlayer tube 10; Tangentially offer many guiding gutters 12 that are connected with its chamber at interlayer tube 10 inwalls.For ease of temperature survey, on 3 sidewalls of combustion chamber, offer temperature survey hole 13.Gasification reactor chamber 7 bottoms offer the funnel shaped of two lateral walls for extending to described slag notch 2 directions in a plurality of cloth air port 9.
