Abstract
The utility model relates to a fire-off protection device for a burner of an annular sleeve kiln, which belongs to the technical field of supporting facilities for kiln combustion. The device comprises a fuel gas conduit; a gradually contracted spray nozzle is formed at one end of the fuel gas conduit while a valve is mounted at the other end; an outer sleeve is mounted outside the fuel gas conduit; a ventilation hole for inhaling combustion air is made on the outer sleeve; and a rotatable windshield drum is sleeved at the ventilation hole. Since the ventilation hole on the outer sleeve can inhale the combustion air, the air-fuel delivery ratio and the mixture gas spraying rate can be adjusted via the valve and the windshield drum, the insertion depth of the fuel gas conduit and the flame length can be changed through screwing the nut, the fuel gas conduit with the gradually contracted spray nozzle and an observation pipe on the burner together form an injection type on-duty flame spray nozzle, and the on-duty flame can uninterruptedly ignite the sprayed fuel gas, stability of the main flame of the burner can be ensured, thereby substantially eliminating the fire-off phenomenon under the conditions that the fuel gas combustion value is smaller than the designed working condition or the gas flow rate is smaller than the designed critical value.
Description
Technical field
The utility model relates to a kind of burner arrangement of annular lime kiln, and especially a kind of annular lime kiln burner anticreep fire device belongs to kiln burning auxiliary facility technical field.
Background technology
When kiln is opened in the sleeve limekiln after the newly-built or overhaul and since this moment the combustion chamber temperature be lower than the ignition temperature of combustion gas, combustion process relies on burner to organize fully.When the calorific value of combustion gas is lower than design conditions, the spread speed of burning is lower than air velocity, the gas flow with burner of perhaps having to for the programming rate of controlling the combustion chamber be reduced to the design critical value when following bispin stream burner can't realize high temperature gases recirculating, these situations all can cause takes off fire.
Understand according to the applicant, when kiln is opened in existing sleeve limekiln,, have to use the higher combustion gas of calorific value to give me a little kiln, baking kiln, and gas quantity is also bigger for fear of taking off fire.This just causes heat input at the beginning bigger than normal, and temperature rises too fast, and far faster than the requirement of baking kiln heating curve, this is just easily to causing harmful effect the service life of anti-material for rate of rise in temperature.
Summary of the invention
The purpose of this utility model is: at the defective that above-mentioned existing burner technology exists, proposes a kind of when fuel gases calorific value is lower than design conditions or gas flow when the design critical value is following, can effectively prevent the fiery device of annular lime kiln burner anticreep of anti-avulsion fire.
In order to reach above purpose, annular lime kiln burner anticreep fire device of the present utility model comprises gas conduct pipe; One end of described gas conduct pipe forms negative throat noz(zle), and the other end is equipped with valve; Described gas conduct pipe is equipped with outer tube outward; Described outer tube is shaped on the air vent that sucks combustion air; Described air vent place is set with the rotatable tube that keeps out the wind.
The utility model further improves, and described outer tube screws by the external screw thread of end and the internal thread of burner sighting tube ball valve, and described gas conduct pipe inserts sighting tube.
Like this, even fuel gases calorific value is lower than design conditions or gas flow is designing below the critical value, because the air vent on the outer tube can suck combustion air, and by the valve and the speed that can adjust air-fuel ratio and gaseous mixture ejection of keeping out the wind, to keep the stable of burner master flame, effectively avoid taking off fiery phenomenon.In addition, the turn nut can change the degree of depth of gas conduct pipe insertion to adjust the length of flame.Above-mentioned gas conduct pipe and the sighting tube on the burner that has negative throat noz(zle) formed injection type flame-thrower nozzle on duty, can continually light the combustion gas of firm ejection with flame on duty, further keep the stable of burner master flame, stop substantially to be lower than design conditions or gas flow is taken off fiery phenomenon when the design critical value is following at fuel gases calorific value.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is Fig. 1 embodiment and burner syndeton schematic diagram
The specific embodiment one
Present embodiment is a kind of annular lime kiln burner anticreep fire device, and it specifically constitutes as shown in Figure 1: gas conduct pipe 1 back segment that has negative throat noz(zle) is shaped on external screw thread, is connected with outer tube 2 by nut 4, and nut 4 is fixedlyed connected with the rear end of outer tube 2.Be shaped on air vent radially on the external cylindrical surface of outer tube 2, in order to suck combustion air.The air vent place overcoat tube 3 that keeps out the wind, so inspiratory capacity can 3 be regulated by the rotation tube that keeps out the wind.The leading portion of outer tube is shaped on external screw thread, and the internal thread that screws in burner sighting tube ball valve 6 is assembled together this device and burner assembly 8.After the assembling, gas conduct pipe 1 inserts sighting tube 7, and insertion depth slightly is shorter than the length of sighting tube 7.Can adjust the speed of air-fuel ratio and gaseous mixture ejection by the valve 5 and the tube 3 that keeps out the wind.Turn nut 4 can change the degree of depth of gas conduct pipe insertion to adjust the length of flame.By the continual combustion gas of lighting firm ejection of flame on duty, can effectively keep the stable of burner master flame, thereby solve when fuel gases calorific value is lower than design conditions or gas flow takes place when the design critical value is following takes off fiery problem.
The anticreep fire that experiment showed, present embodiment is respond well, in the time of can effectively avoiding fuel gases calorific value to be lower than design conditions or gas flow take off fiery phenomenon what the design critical value took place when following.In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
