Abstract
The utility model relates to a device for preventing peeping in the fire detection of an anti-oil reduction ignition burner, which belongs to the field of the parts of boiler burners in power plants. According to the device for preventing peeping in the fire detection of the anti-oil reduction ignition burner, the following design is realized based on an existing oil reduction igniter: at semi-section stainless steel tube is welded from below the tail of the oil reduction ignition burner to above a steady flow hood as a light pipe support; a light pipe is arranged in the light pipe support; a blockage prevention hole is arranged on the light pipe which is 30cm from the left side of the tail of the oil reduction ignition burner, and a rectangular square groove is arranged above the steady flow hood; and the light pipe support passes through the tail of the burner, and the stainless steel tube with the diameter being 25 is welded on the right side, and a screw is installed as a jackscrew for fixing the light pipe. The device for preventing peeping in the fire detection of the anti-oil reduction ignition burner has the beneficial effects that: the analogue signal of an existing device when other burners are ignited but the oil gun of the burner is not ignited is 80 percent to 100 percent of a full valve, and the switching signal is with fire; and the analogue signal when other burners are ignited but the oil gun of the burner is not ignited is 2 percent to 5 percent of the full valve, and the switching signal is without fire. According to the device for preventing peeping in the fire detection of the anti-oil reduction ignition burner, the flame of the burner can be only seen in the fire detection, so that the phenomenon of peeping is prevented.
Description
Technical field
The utility model belongs to the boiler of power plant combustor component.
Background technology
In boiler of power plant, the flame detecting probe of few-oil ignition combustion device is placed horizontally at few-oil ignition combustion device afterbody usually, shown in accompanying drawing 1.Like this, when other burner was lighted, flame detecting probe can detect the oily flare up fire of other burners through this burner outlet, peeped phenomenon thereby produce, and made the control system can't correctly judge the flame situation of this burner oil gun.
Summary of the invention
The purpose of the utility model is to improve the few-oil ignition fire monitor equipment, prevents the fiery generation of peeping phenomenon of examining.
The technical scheme of the utility model is, on existing few-oil ignition device basis, doing following design: partly cut open stainless steel tube as the light pipe support from few-oil ignition combustion device afterbody below to an internal diameter 30mm of current stabilization cover top welding; The light pipe of an internal diameter 18mm is installed in the light pipe support; On 30cm place, few-oil ignition combustion device afterbody left side light pipe, leave the anti-plug-hole of diameter 8mm; Process Φ 20 coarse threads at light pipe and flame detecting probe connecting portion; Length is 15mm, above the current stabilization cover, opens the rectangle square groove of a 25 * 25mm; The light pipe support passes the burner afterbody, its right side welding Φ 25 stainless steel tubes, and length is 50mm, tapping 5mm internal thread on its tube wall is installed the 5mm screw as the fixing light pipe of jackscrew.
The beneficial effect of the utility model: existing apparatus in other burners igniting back and this burner oil gun when not lighting a fire analog signals be 80%-100% of full value; The switching value signal is for there being fire; Analog signals is 80-100% of full value behind this burner grease gun igniting, and switching value is for there being fire; The utility model in other burners igniting back and this burner oil gun when not lighting a fire analog signals be 2%-5% of full value, the switching value signal is not for there being fire, behind this grease gun igniting analog signals for full be worth 60-80%, switching value is for there being fire.The utility model makes fiery inspection can only see the flame of this burner, has prevented to peep the generation of phenomenon.
Description of drawings
Accompanying drawing 1 is existing few-oil ignition device sketch map.
Accompanying drawing 2 is the utility model structural representations.
The specific embodiment
The utility model structure is seen shown in the accompanying drawing 2; With existing few-oil ignition device same section shown in the accompanying drawing 1 be: few-oil ignition combustion device 1 comprises that combustion air inlet 2, wind powder inlet 3, burner outlet 4 and level are installed in the current stabilization cover 7 of burning torch 5, oil gun 6 and the oil gun front end of burner afterbody 9, wherein existing few-oil ignition device flame detecting probe 8 horizontal positioned.The utility model improvements are setting angle and modes of flame detecting probe 8, implement in such a way:
1, increases light pipe support 12.Partly cut open stainless steel tube from an internal diameter 30mm of few-oil ignition combustion device afterbody 9 belows to current stabilization cover 7 tops welding; Smooth surface does not have welding slag; As the support of light pipe 11, light pipe 11 is freely stretched on support 12 and rotate, and can prevent light pipe 11 temperature distortions.
2, increase light pipe 11.The light pipe 11 of an internal diameter 18mm is installed in light pipe support 12; On 30cm place, few-oil ignition combustion device afterbody 9 left side light pipe 11, leave the anti-plug-hole 10 of diameter 8mm; Blast through combustion air inlet 2 purges light pipe 11, prevents that dust stratification from stopping up light pipe 11 and the normal operation of influence fire inspection.Process Φ 20 coarse threads at light pipe 11 and flame detecting probe 8 connecting portions, length is 15mm, and flame detecting probe 8 is installed.Above current stabilization cover 7, open the rectangle square groove 13 of a 25 * 25mm, make few oily flame light can shine flame detecting probe 8.
3, increase the light pipe fixture.Light pipe support 12 passes burner afterbody 9, one section Φ 25 stainless steel tube of its right side welding, and length is 50mm, tapping 5mm internal thread on its tube wall is installed the 5mm screw as the fixing light pipe 11 of jackscrew.Light pipe 11 can advance on light pipe support 12 or retreat, and light-inletting quantity is carried out trickle adjusting.
