Abstract
The utility model relates a multi-level strengthened combustor, which includes a fuel gas conveying system, a fuel gas nozzle, a combustion-supporting gas, a fuel gas and combustion-supporting gas mixing area, a combustion area and a diffusion area, wherein a combustion pressurized mixing area is arranged between the fuel gas and combustion-supporting gas mixing area and the combustion area. The multi-level strengthened combustor further improves the mixing degree of carbon monoxide and oxygen in combustion products and improves the combustion effect, the fuel gas (pulverized coal granules) can burn more sufficiently, and the carbon monoxide persistence amount in combustion waste gas is reduced, therefore, the purposes of saving energy and reducing emission can be achieved, the multi-level strengthened combustor has the characteristics of energy conservation and environmental protection, moreover, the structure is simple and the cost is low.
Description
Technical field
The utility model relates to a kind of multistage intensified burner.
Background technology
What fuel combustion comprised fuel and combustion air mixes, processes such as fire burns, flame spread, in combustion process, be accompanied by the rapid expansion and luminous, the exothermic phenomenon of gas, under the normal pressure situation, the boundary layer that forms between fuel mix and the flame is unfavorable for the rapid mixing of fuel, thereby is unfavorable for fuel conflagration and completing combustion.General gas (water-coal-slurry) combustion apparatus is made up of with combustion-supporting gas mixed zone, combustion zone, diffusion region etc. combustion gas induction system, combustion gas (water-coal-slurry) shower nozzle, combustion-supporting gas (air or oxygenation gas), combustion gas (water-coal-slurry), this system is because combustion gas and combustion-supporting gas mixing velocity are slow, burning is insufficient, thereby the amount retained of carbon monoxide is big in the burnt gas, this combustion system causes the waste of fuel on the one hand, and these gases efflux the pollution of environment bigger on the other hand.
The utility model content
Its purpose of the utility model just is to provide a kind of multistage intensified burner, has the characteristics of energy-saving and environmental protection, and simple in structure, and cost is low.
The technical scheme that realizes above-mentioned purpose and take, comprise combustion gas induction system, gas spray head, combustion-supporting gas, combustion gas and combustion-supporting gas mixed zone, combustion zone and diffusion region, be provided with burning supercharging mixed zone between described combustion gas and combustion-supporting gas mixed zone and the combustion zone.
With prior art mutually, the beneficial effects of the utility model are,
Owing to adopted the structural design of supercharging mixed zone, thereby further improved the mixability of carbon monoxide and oxygen in the combustion product, improved combustion efficiency, combustion gas (coal dust granule) burning is more abundant, make that the amount retained of carbon monoxide reduces in the burnt gas, thereby reach the purpose of energy-saving and emission-reduction, have the characteristics of energy-saving and environmental protection, and simple in structure, cost is low.
Description of drawings
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is this apparatus structure schematic diagram.
Fig. 2 is one of this device embodiment structural representation.
The specific embodiment
Comprise combustion gas induction system 1, gas spray head 3, combustion-supporting gas 2, combustion gas and combustion-supporting gas mixed zone 4, combustion zone 5 and diffusion region 6, as shown in Figure 1, be provided with burning supercharging mixed zone 9 between described combustion gas and combustion-supporting gas mixed zone 4 and the combustion zone 5.
Described burning supercharging mixed zone 9 can be one-level supercharging mixed zone 7 and two-stage supercharging mixed zone 8, as shown in Figure 2.
Described supercharging mixed zone 9 is taper.
Operation principle:
Under the situation of same fuel supply and combustion air, because the volume in the volumetric ratio ordinary combustion district of supercharging mixed zone 9 is little, the gas that burning produces is under the extruding of little outlet, form high-temperature high-pressure air flow easily, the mixing velocity and the mixability of fuel and combustion air have been quickened in the turning effort of air-flow simultaneously, the just quick and complete burning of energy after the mist of these good mixings enters second anallobar or combustion zone, thus flame temperature and the content that reduces carbon monoxide in the flue gas improved.
The contrast of relevant technologies data is as follows during use:
⒈ roller kilns length: 178.35m
⒉ product category: 800*800 polished bricks
The ⒊ daily output: 8000m2
Other relevant data of ⒋
Produce 8000000000 square metres of calculating of wall floor tile per year by the whole nation, coal-fired 4,000,000 tons of year saving, discharge amount of exhaust gas reduces by 40,000,000,000 m3, and the CoO2 discharge capacity reduces by 2,500,000,000 m3, saves energy 2.8 hundred million degree.From above analysis result, the application of this burner has good economic benefit and social benefit.
