Description
Technical field
The utility model belongs to boiler plant technical field, is specifically related to one and is applicable to oil burning boiler, the high speed ignition rifle of gas fired-boiler and pulverized-coal fired boiler.
Background technology
At present, oil burning boiler, in the time starting, often adopts high-energy ignition rod to be advanced into oil gun shower nozzle, and the mode of directly getting angry is carried out pilot fuel flame.In fact,, owing to being the igniting of black furnace state, igniting reliability is not high.Part boiler has adopted gas burning torch pilot fuel, but such gas burning torch energy consumption is high, and flame holding is inadequate, is subject to furnace pressure and combustion air amount impact.Meanwhile, boiler is in the time of underrun state, and fuel consumption is less, and fuel oil operating pressure off-design value is more, and oil burner flame quality is poor, and stability is bad.
Utility model content
The utility model is not high with burning torch reliability for current oil burning boiler, and the problem that flame holding is low proposes a kind of high speed ignition rifle of oil burning boiler.
A kind of high speed ignition rifle of oil burning boiler, be assemblied on oil burner by mounting flange 9, one end of combustion air passage 4 is provided with flame observation visor 3, the other end is provided with blender 6, the sidepiece of combustion air passage 4 is also provided with combustion air interface 2 and combustion gas interface 5, the front portion of blender 6 is provided with shrinks cone 8, shrinks cone 8 and is connected with interconnector 10, and ignitor 7 and ignition are observed visor 1 and be arranged in the connecting pipe of shrinking between cone 8 and blender 6.
Combustion air interface 2 is connected with combustion air pipeline, and combustion air pipeline is provided with Pressure gauge and hand valve.
Described ignitor 7 is vehicular engine spark plug, and the button of getting angry is controlled by PLC.
Spray orifice 11 in combustion air passage 4 is set to two rows.
Burning torch operation principle of the present utility model is: combustion gas enters into combustion gas air collecting chamber, by gas jet orifice, sprays into combustion air chamber, tentatively mixes with air.Through blender, both are well mixed, and are shrinking cone place, and gaseous mixture is got angry electrode and ignited, and volume expands rapidly, sprays at a high speed interconnector, forms the strong flame of high speed.
The beneficial effects of the utility model: use burning torch igniting of the present utility model reliable and stable, success rate is high; The mode that adopts premixed combustion, the flame of generation is powerful and vigorous, is not subject to the impact of furnace pressure and combustion air amount, and antijamming capability is strong, the torch that ignites as fuel oil flame preferably; This burning torch gas consumption is low, can be fuel oil under boiler at low load state and continues companion's burning, is conducive to stable operation of the boiler.

Wherein, 1-gets angry and observes visor, 2-combustion air interface, and 3-flame observation visor, 4, combustion air passage, 5-combustion gas interface, 6-blender, 7-ignitor, 8-shrinks cone, 9-mounting flange, 10-interconnector, 11-spray orifice.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
A kind of high speed ignition rifle of oil burning boiler, as shown in Figure 1-2, be assemblied on oil burner by mounting flange 9, one end of combustion air passage 4 is provided with flame observation visor 3, the other end is provided with blender 6, and the sidepiece of combustion air passage 4 is also provided with combustion air interface 2 and combustion gas interface 5, and the front portion of blender 6 is provided with shrinks cone 8, shrink cone 8 and be connected with interconnector 10, ignitor 7 and the observation visor 1 of getting angry are arranged in the connecting pipe of shrinking between cone 8 and blender 6.
The burning torch working method of the present embodiment is as follows: while needing igniting, first connect combustion air, then ignitor starts to get angry, and sets subsequently self-supporting type pressure reducing valve downstream pressure, and PLC opens gas cut off valve, and the gaseous mixture of combustion gas and combustion air is ignited.Mixed flame, by interconnector ejection at a high speed, forms high-speed flame, in order to light fuel oil flame.
Flame situation after igniting can be judged by oil burner flame detector, also can observe by the flame observation visor 3 that is located at burning torch tail end.
This burning torch is provided with an ignition in ignition position, electrode opposite simultaneously and observes visor 1, in order to check the health ignition situation of electrode.
When the spray orifice 11 of combustion gas air collecting chamber (combustion air passage 4) designs, need be designed to two rows, when quantity m, the n of two rounds and aperture d1, d2 design, to pass through design accounting, object is to form different Jet Penetration Depths, as illustrated with reference to figure 3, be used for improving the mixed effect of combustion gas and combustion air.
This burning torch self does not need complicated fire rod propulsion plant is set, and adopts common vehicular engine sparking-plug electrode to light, and gas consumption is lower, approximately 2～5Nm
3/ h.Can be used for the igniting of furnace fuel oil burner, also can be used for the igniting of high power gas burner, through possible variation and modification, this burning torch also can be used in the igniting of pulverized-coal fired boiler, and this all belongs to the scope of claims protection.
