Abstract
The utility model provides a boiler flame detecting system with protection device, examine the probe and examine the electric controller of being connected of probe with the fire at the fire on one side of the furnace including the setting, the detection furnace inside flame burning condition and output signal through it is accurate that the probe is examined to the fire transmit for the controller, on furnace's outer wall fixed be equipped with one with inseparable laminating and fixed connection's the stainless steel of furnace outer wall, stainless steel has seted up the opening in the surface, the protective sleeve that fixed connection no. 1 was made by refractory material on stainless steel, protective sleeve both ends opening, it passes the opening extends to in the furnace, the fire is examined the probe and is worn to establish in protective sleeve, and its one end that stretches into in the furnace is located inside the protective sleeve. Through examine the transformation that the probe stretched into protective case before to flame detecting system fire for can not appear the fire again and examine the phenomenon of probe department coking, make flame detecting system's normal reliability service.
Description
Technical field
The utility model relates to boiler safety monitoring system field, specifically relates to a kind of boiler flame detection system with protective device.
Background technology
Fire inspection is the important component part of FSSS burner hearth safety monitoring system, and it is the visual plant that operations staff grasps furnace flame situation.Because flare up fire exists the important logic of jumping mill and MFT, the bad serious threat unit safety operation of flare up fire.
Boiler extinguishment protection is one of unit main protection, is the prerequisite protection system of modern large-sized boiler.Along with the continuous increase of unit capacity, the structure of boiler plant and auxiliary equipment thereof become and become increasingly complex, and the factor affecting boiler operatiopn also increases thereupon, as unstable combustion, easily cause burner hearth to stop working, as further misoperation, then easily furnace explosion occur.And the operational factor of furnace flame detection system energy continuous monitoring combustion system and state, the information detected is fed back to furnace safeguard supervisory system in time, by predetermined logical program combustion apparatus operated and control, and send action command emergency cut-off main fuel where necessary, by various program control and interlock, make the relevant devices in combustion system carry out operating to control to avoid fault spread in strict accordance with certain logical program, ensure the device security of boiler combustion system and unit.
After the transformation of double source 1-4 stove low NO, on-the-spot flame detector system goes wrong, and coal fire inspection is frequent, and occur cannot the situation of flame detection; Oil fire detects now in emergency circumstances, and boiler puts into operation oil gun, and oil fire can't detect the situation that flame causes oil gun to exit.
Because flame detection system often occurs serious judging phenomenon without fire, but Actual combustion is stablized, and is observed by on-the-spot long-term follow, determines that reason is that probe anterior coking of popping one's head in running is serious, to cause after coking flame detecting probe detection not out flame.
Because former boiler plant is after low NO transformation, cause flame detector system to go wrong, mainly there is coking phenomenon in probe place, causes coal fire to examine, the inspection of oil fire cannot detect flame, and likely cause the possibility of full furnace flame false protection.
Utility model content
The utility model is mainly for solving above-mentioned Problems existing; a kind of boiler flame detection system with protective device is provided; by to the transformation stretching into protective casing before flame detector system flame detecting probe; make the phenomenon that can not occur the coking of flame detecting probe place again, the normal reliable of flame detector system is run.
For solving above-mentioned Problems existing, the technical scheme that the utility model adopts is: a kind of boiler flame detection system with protective device, comprise the flame detecting probe being arranged on burner hearth side and the controller be electrically connected with flame detecting probe, detect burner hearth internal flame combustion case accurately by flame detecting probe and output signal and pass to controller, the outer wall of burner hearth is fixed with one fit tightly and the stainless-steel sheet be fixedly connected with hearth outer wall, stainless-steel sheet surface offers port, stainless-steel sheet is fixedly connected with a protection sleeve be made up of refractory material, protection sleeve both ends open, it extends in burner hearth through described port, flame detecting probe is located in protection sleeve, and its one end stretched in burner hearth is positioned at protection sleeve inside, flame detecting probe is provided with signal projector and signal receiver, and the flame temperature detected is transmitted into signal receiver by signal projector, signal projector and the equal connection control device of signal receiver.
Further, described protective casing and the junction of stainless-steel sheet arrange smooth to prevent junction in fire defector process from producing coking.
The beneficial effect that the utility model brings is: by the transformation stretching into protective casing before flame detector system flame detecting probe, make the phenomenon that can not occur the coking of flame detecting probe place again, the normal reliable of flame detector system is run.
