Summary of the invention
To be solved in the utility model is exactly that existing fluid bed uses centrifugal blower as air-blast device more, blast is unstable, fluid bed is difficult to fluidisation, be forced to the problem stopping, provide a kind of high pressure positive blower and normal temperature hybrid chamber of utilizing to combine, make blast in the fluid bed load range of 10%-120%, all keep stable fluid bed air-blast device.
Biomass thermal combustion gas injection burner of the present utility model, it is characterized in that this burner comprises hot fuel gas inlet, hot gas diversion pipe, forced air mozzle and lighting-up tuyere, hot fuel gas inlet is arranged on same one end that hot fuel gas inlet and forced air mozzle are arranged on hot gas diversion pipe, hot fuel gas inlet and hot vertical connection of gas diversion pipe, forced air mozzle gos deep in hot gas diversion pipe, its gas outlet is positioned at hot fuel gas inlet below, and lighting-up tuyere is arranged on the hot gas diversion pipe other end.
On described its gas outlet of forced air mozzle, an air nozzle is installed, improves the air velocity of ejection in forced air mozzle.
Described lighting-up tuyere is provided with stable flame hole, and stable flame hole is several, plays steady flame.
Described hot gas diversion pipe outer wrap has a protective layer; between protective layer and hot gas diversion pipe, form an auxiliary air interlayer; on protective layer, be provided with an auxiliary air import; auxiliary air import is communicated with auxiliary air interlayer; protective layer and and stable flame hole between position auxiliary air guide vane is installed; utilize blade to make auxiliary air enter stable flame hole, improve the mixing ratio of air and combustion gas, be beneficial to combustion gas completing combustion.
Described hot gas diversion pipe is sequentially divided into hybrid chamber, collapsible tube, mixing tube and pressure and recovers four sections of pipes, hybrid chamber is connected with forced air mozzle and hot fuel gas inlet, pressure recovers Guan Yuyu stable flame hole and connects, and pressure recovery pipe and collapsible tube are tapered, and arranges in opposite directions.
Different from conventional injection burner, the pressure-air that the utility model is usingd after pressurization is as ejection gas, and high-temperature biomass gas is as by ejection gas.Pressure-air accelerates by lobe or multi nozzle nozzle, realizes the large injection ratio of hybrid chamber, has increased the contact area of air and hot combustion gas, and strengthening mixes.At lighting-up tuyere, stable flame hole is set, realizes the automatic steady flame of hot combustion gas.At the outer wrap auxiliary air interlayer of hot gas diversion pipe, the completing combustion for hot combustion gas provides enough air on the one hand, plays on the other hand the effect of insulation.
Biomass thermal combustion gas injection burner of the present utility model, design science, simple in structure, easy to use, also have the following advantages:
1, adopt pressure-air as power source, hybrid chamber, as workpiece, does not have running gear, reliable and stable;
2, adopt automatic lighting-up tuyere on duty to carry out steady flame, close up anti-backfire;
3, design lobe or multi nozzle nozzle replaces traditional nozzle, overcome the defect of conventional hybrid chamber aspect injection hot gas.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Wherein, hot fuel gas inlet 1, hybrid chamber 2, forced air mozzle 3, nozzle 4, collapsible tube 5, mixing tube 6, pressure recovers pipe 7, auxiliary air import 8, auxiliary air guide vane 9, stable flame hole 10, lighting-up tuyere 11, auxiliary air interlayer 12.
