The utility model discloses a burner suitable for a coal mill, which comprises an outer sleeve, an inner sleeve, a coal nozzle installed on one end face of the inner sleeve, and an igniter on the other end face; the outer sleeve shell An air distribution plate and a sleeve baffle are arranged on the body, and the air distribution plate is connected to a manual external air adjustment driving rod. A thermocouple is installed at the coal nozzle of the inner sleeve, a thermocouple is installed beside the coal tangential inlet outside the outer sleeve, and a thermocouple is installed beside the igniter of the inner sleeve. The utility model has a novel structure, can monitor the rising point of the temperature in the burner in time, and can send out an alarm signal to prompt the operating personnel to take measures to avoid fire danger.
Description
Technical field
The utility model relates to coal pulverizer, particularly is applied to the burner of coal pulverizer.
Background technology
One end band nozzles of existing coal pulverizer, the other end also is with nozzles, if after a burner sends " flame loses " signal, will close the BSOD of a pair of burner, this moment, exerting oneself of coal pulverizer will be reduced half, and the coal dust of an end will flow to the opposite side of local terminal in the coal pulverizer, do not catch up with if the coal pulverizer air quantity is adjusted moment, two nozzles coal powder densities only depositing are strengthened even improve primary air velocity, the ignition point that causes a pair of nozzles that are left is away from revolving mouth.Because flame detecting probe is installed in the side top of burner, oblique from top to bottom desirable flame kernel to burner nozzle, after ignition point is passed forward, flame detecting probe does not just detect flame, what measure is pitch-black breeze airflow, so " flame loses " signal is sent in the burner fire inspection, in fact still can see flame from burner observation window (because this window is horizontal angle mount) on the spot.
According to the structure of burner, the peep hole of flame-detecting probe is installed in the passage of transferring secondary wind in the burner, and on the end plate between promptly interior gear shift plate and the outer tube, the observation window of burner also is to be contained in this position.Because after secondary wind enters burner through air distribution plate, form eddy flow through investigation mission outside the city or town plate washer and interior gear shift plate, transfer the files in particularly entering and form eddy current after the secondary wind of plate impacts outer tube, because of the peep hole of flame-detecting probe just is in the vortex, cause part secondary wind to enter peep hole, because secondary wind carries ash, the time has been grown and has just accumulated in the pipeline of peep hole, pollutes the flame detecting probe minute surface flame detecting probe is surveyed less than flame.
Cause the coal pulverizer tripping operation owing to exist the problems referred to above, burner just can send out " flame loses " signal, cause burner to revolve a mouthful coking.Fire inspection airduct road dust stratification has blocked flame detecting probe, makes probe detection less than flame, and under the normal situation of catching fire, mistake is sent " flame loses " signal, causes the coal pulverizer tripping operation.
The utility model content
In order to overcome the defective that above-mentioned prior art exists, the utility model provides a kind of boiler coal-ash storehouse, and burner structure is redesigned, avoid taking place the problems referred to above, can in time monitor the flame temperature at nozzles place, and send alarm signal, be convenient to the operations staff and adopt an effective measure.
To achieve these goals, the technical solution of the utility model is as follows:
Be applied to the burner of coal pulverizer, comprise igniter, outer sleeve, inner sleeve, be installed in the coal nozzle on end face of inner sleeve, the coal nozzle is the combustion flame place;
Described igniter is installed in another end face of described inner sleeve, and igniter is communicated with by the interior pipe of described inner sleeve, and described coal nozzle will inspire combustion flame during initial igniter;
Air distribution plate and sleeve baffle plate are set on the described outer sleeve housing, many exhausting holes are set on the described air distribution plate, be convenient to blowing; Described air distribution plate connects manual investigation mission outside the city or town wind drive rod.
Be characterized in that the thermocouple temperature measurement element is installed in many places in described burner, be used for monitoring each point temperature in the burner.
Wherein, described inner sleeve coal nozzle place is equipped with thermocouple, the other thermocouple of installing of the coal tangential inlet in the outer sleeve outside, and inner sleeve igniter side is installed thermocouple.
The coal tangential inlet of above-mentioned inner sleeve igniter, inner sleeve coal nozzle place and outer sleeve is other to be the anxious easily poly-each point that rises of temperature in the burner, the corresponding thermocouple temperature measurement element of installing at described each point place, can in time monitor its temperature, if overstep the extreme limit alarm temperature, will send signal makes the operations staff manually transfer to other localities the wind drive rod by described air distribution plate blowing cooling, cooling is in time avoided unexpected and is taken place.
The beneficial effects of the utility model are by at the easily anxious poly-rising each point of burner temperature thermocouple temperature measurement element monitor temperature being installed, can effectively avoid sending false command because of surveying less than flare up fire, and influence other working procedure of coal pulverizer.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment:
For creation characteristic of the present utility model, technological means and goal of the invention are easy to understand, further set forth the utility model below in conjunction with specific embodiment.
Embodiment:
Referring to Fig. 1, be applied to the burner of coal pulverizer, comprise igniter 1, outer sleeve 2, inner sleeve 3, be installed in the coal nozzle 4 on 3 one end faces of inner sleeve, coal nozzle 4 is the combustion flame place;
Igniter 1 is installed in another end face of described inner sleeve 3, and igniter 1 is communicated with by the interior pipe of described inner sleeve 3, and described coal nozzle 4 will inspire combustion flame during initial igniter 1;
Electric sleeve barrel 9 be arranged on manual accent wind drive rod 7 on;
Be characterized in that the thermocouple temperature measurement element is installed in many places in described burner, be used for monitoring each point temperature in the burner.
Wherein, described inner sleeve 3 coal nozzles 4 places are equipped with thermocouple 41, the coal tangential inlet 22 other thermocouples 21 of installing in outer sleeve 2 outsides, and inner sleeve 3 igniter sides are installed thermocouple 31.
The coal tangential inlet of above-mentioned inner sleeve 3 igniters 1, inner sleeve 3 coal nozzles, 4 places and outer sleeve 2 is other to be the anxious easily poly-each point that rises of temperature in the burner, the corresponding thermocouple temperature measurement element of installing at described each point place, can in time monitor its temperature, if overstep the extreme limit alarm temperature, will send signal makes the operations staff manually transfer to other localities the wind driving by described air distribution plate blowing cooling, cooling is in time avoided unexpected and is taken place.
More than show and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
