Background technology
At present, traditional boiler combustion checkout gear generally adopts the method for industrial TV monitoring, it is the burner hearth safety monitoring system, it judges the combustion position of boiler by flame color and brightness, to guarantee that combustion flame does not extinguish, it can be under the various operating conditions such as normal operation of boiler and start and stop, pay close attention to continuously parameter and the state of combustion system, constantly carry out logic judgement and computing, send in case of necessity action command, make combustion apparatus according to rational program complete operation, to guarantee the safety of boiler combustion.But it concentrate on mainly that flame " has " or the judgement of " nothing " on, the safe operation that is difficult to guarantee boiler to improving performance driving economy, reduce pollutant emission (clean burning), realize the higher level field development such as inline diagnosis of burning.
Chinese patent 200420076978 discloses a kind of three dimension temperature field realtion monitor in coal burning boiler, this installs at the boiler furnace hopper to the burner hearth zone of furnace arch, furnace nose, along boiler height direction layered arrangement camera probe, at least arrange two for every layer, under its visual angle center line is oblique, the vision signal of each camera probe is sent in the Video segmentation device and is synthesized a road signal, then sends in computer and process.Above-mentioned camera probe is preferably every 4～6 meters layout one decks, and the angle γ of the rib of its visual angle center line and boiler is that 40 degree are advisable between 50 degree.
But the layout of its camera probe is generally taked CCD and laser technology, CCD measures the wide low precision of area, and laser temperature-measuring can realize short distance but inner flue gas of the stove is many, disturbance is large, can't accurately measure, cause certainty of measurement not high, be unfavorable for realizing the accurate control of burning.
The utility model content
The purpose of this utility model is for the technological deficiency existed in prior art, and a kind of boiler temperature detection system that convenient certainty of measurement is high that arranges is provided.
For realizing that the technical scheme that the purpose of this utility model adopts is:
A kind of boiler temperature detection system, comprise the probe be arranged on boiler and the information processor be connected with described probe data, described boiler is the quadrangle tangential circle stove, described probe is arranged on flame kernel location on the upper side, and described probe is on eight four sidewalls that are arranged in twos respectively the quadrangle tangential circle stove, the setting of staggering of the probe of two opposite side walls.
Eight temperature measurers installations are installed are respectively two, left two right sides below the boiler furnace arch, furnace nose, under upper two platforms, two staggered forms are installed, and utilize the principle of spectral absorption, and temperature is received comprehensively, thereby have better grasped temperature cross section in burner hearth.
Described probe is arranged on the place apart from boiler bottom 30m-40m.
Described probe is far-infrared spectrum formula boiler smoke temperature measurer.
At least one described boiler smoke temperature measurer is arranged on the top of the burner of quadrangle tangential circle stove.
Compared with prior art, the beneficial effects of the utility model are:
Boiler temperature detection system of the present utility model has the advantages such as fast, noncontact of response time, safe and convenient to use and life-span be long, can be widely used in the aspects such as metallurgy, electric power, chemical industry, glass manufacture, food, tobacco processing and equipment fault diagnosis.
The accompanying drawing explanation
Figure 1 shows that the probe distribution schematic diagram of boiler temperature detection system.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1, boiler temperature detection system of the present utility model, comprise the probe 2 be arranged on boiler 1 and the information processor be connected with described probe data, described boiler is the quadrangle tangential circle stove, described probe is arranged on flame kernel side on the upper side, substantially be positioned at the position of boiler bottom 30-40m, and described probe is on eight four sidewalls that are arranged in twos respectively the quadrangle tangential circle stove, the setting of staggering of the probe of two opposite side walls.Wherein, described probe is far-infrared spectrum formula boiler smoke temperature measurer.
The quadrangle tangential circle stove is mainly the boiler of coal dust burning, fuel oil, combustion gas etc., and burner hearth is square, and at four jiaos, injector (burner) is set, and four jiaos of while burner oils when burning, form a circle of contact fully to mix, the enhanced burning effect in the middle of burner hearth.
The 300MW unit of specifically take is example, described 8 boiler smoke temperature measurers are arranged on a plane apart from about 33 meters places, bottom, this position is positioned at flame kernel on the upper side, temperature is the highest, temperature field and wind facies can not cause too much disturbance to stable, can effectively improve the Stability and veracity of monitored data.Being arranged on simultaneously flame kernel just can observe on the upper side in ,Zai hot-zone, overheated zone, flame temperature should be lower than the melting softening temperature of ash, the ash of melting can corrode and block overheated pipeline and reheating pipe road, reduce boiler thermal output and maintenance period, boiler water wall, superheater, the continuous coking and slagging of reheater meeting, hinder heat exchange, reduce the thermal efficiency.
Simultaneously, arrange eight temperature measurers to TT&C system imaging played good effect, by observing three-dimensional observing and controlling sectional view, analyze burner hearth combustion case, calibration flame kernel, impact of flame on the walls etc. can effectively prevent the interruption of services such as boiler coke, boiler tube explosion, stove chamber fire-extinguishing, guarantee efficiency of combustion, thermal conversion efficiency, reduce cost of electricity-generating, the prolonged boiler maintenance period, reduce maintenance cost.
Described boiler smoke temperature measurer, to forming the fume component analysis imaging, can effectively help power plant to control flame temperature, adjusts flame kernel, reduces the generation of NOx and the generation of coking and slagging.Thereby optimize power plant's efficiency of combustion comprehensively, reach the requirement of energy-conservation, low-carbon (LC), environmental protection.
Further, described boiler smoke temperature measurer can also be arranged on the top of boiler-burner, single and whole burners is monitored, and adjusted in time the boiler integral combustion, formation temperature image system.
For the quadrangle tangential circle stove, 8 infrared radiation thermometers of system bearing, can draw a plurality of gas concentrations, temperature profile analysis chart simultaneously.Simultaneously, the O recorded in real time
2, CO, CO
2The Pressure, Concentration, Temperature field data also transfers to information processor by OPC and other communications protocol, is transferred to PC and carries out the generation of boiler cross section.That is to say, described information processor and existing control system are similar, and only needing relatively to adjust a little parameters can realize, can realize for a person skilled in the art.
Boiler temperature detection system of the present utility model has the advantages such as fast, noncontact of response time, safe and convenient to use and life-span be long, can be widely used in the aspects such as metallurgy, electric power, chemical industry, glass manufacture, food, tobacco processing and equipment fault diagnosis.
The above is only preferred embodiment of the present utility model; it should be noted that; for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
