Description
Technical field
A kind of coal gas burner is the utility model is related to, used coal gas burner, belongs to industrial furnace especially on industrial furnace
Equipment technical field.
Background technology
At present, widely used coal gas burner has a kind of centre wind to grow short flamed mixed gas burner on industrial furnace, its
It is characterized in one piece of adjusting flap is installed in crust of weathering upper end, gas pipe is stretched into the crust of weathering, has one on the horizontal pipe of gas pipe
Sighting tube, central air hose is installed between gas pipe and sighting tube, has fire hole in the sidepiece of burner.The coal gas burner can pass through
The flame between the long flame of adjusting flap acquisition, short flame or length is rotated, it is easy to operate, and igniting is easy, beneficial to observation.But
It is that, because the sectional area that coal gas sprays in coal gas burner is big, when calorific value of gas fluctuation is increased, the gas flow used can subtract
Few, the speed that coal gas sprays reduces, even if by rotating adjusting flap, it is also difficult to the flame between long flame or length is obtained,
The needs of industrial stove heat can not be met, waste fuel；More seriously, increase when calorific value of gas fluctuates, and coal gas burns
Mouth load reduce when, the gas flow used can greatly reduce, coal gas spray speed can very little, easily cause coal gas burner,
Gaspipe line is tempered, and is damaged pipeline equipment, is caused the accident.
Utility model content
The utility model purpose is to provide a kind of coal gas burner, can be obtained moderate according to the height situation of calorific value of gas
The length of flame, and then meet the demand for heat of industrial furnace, solve problem present in background technology.
The technical solution of the utility model is：
A kind of coal gas burner includes coal gas core pipe, coal gas sleeve pipe, combustion air intake stack, swivel flap, peep-hole, igniting
Hole, nozzle and flow distribution plate, the both sides of nozzle are respectively equipped with peep-hole and fire hole, nozzle respectively with coal gas core pipe, coal gas sleeve pipe
Connected with combustion air intake stack, the coal gas sleeve pipe is enclosed in coal gas core pipe, axis direction in the combustion air intake stack
Flow distribution plate is provided with, flow distribution plate is rotatablely connected with swivel flap.
The coal gas core pipe is connected with thinner gas piping, and coal gas sleeve pipe is connected with thicker gas piping.
The coal gas core pipe and coal gas sleeve pipe are respectively equipped with air-supplying valve.
The coal gas core pipe and coal gas sleeve pipe are put in combustion air intake stack close to one end of nozzle.
The combustion air intake stack can make nozzle produce inner ring wind and outer ring wind by swivel flap and flow distribution plate.
Using the utility model, when calorific value of gas is low, the air-supplying valve in coal gas core pipe and coal gas sleeve pipe is opened；When
When calorific value of gas is high, the air-supplying valve for the core pipe that only turns on the gas-fire, the air-supplying valve on coal gas sleeve pipe is closed；When calorific value of gas is medium
When, the air-supplying valve of coal gas core pipe is closed, the air-supplying valve only to turn on the gas-fire on sleeve pipe.Simultaneously can also be by adjusting combustion air
Swivel flap in intake stack, the flame between long flame or length is obtained, fully meet the needs of industrial stove heat.
The beneficial effects of the utility model are：Rational spouting velocity when coal gas is sprayed by nozzle is ensure that, can effectively be kept away
Exempt from nozzle, gaspipe line tempering, damage pipeline equipment.Moderate flame length can be obtained according to the height situation of calorific value of gas
Degree, and then meet the demand for heat of industrial furnace.Simple in construction, easy to operate, igniting is easy, securely and reliably, can be wide beneficial to observation
It is general to be applied on industrial furnace, blast furnace gas, coal gas of converter and coke-stove gas are made full use of, saves the energy, increases the performance of enterprises.
Brief description of the drawings
Fig. 1 is the utility model structure diagram；
Fig. 2 is the utility model A to schematic diagram；
In figure：Coal gas core pipe 1, coal gas sleeve pipe 2, combustion air intake stack 3, swivel flap 4, inner ring wind 5, outer ring wind 6, peep
Window 7, fire hole 8, nozzle 9, flow distribution plate 10.
Embodiment
Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.
Referring to the drawings 1,2, a kind of coal gas burner, coal gas core pipe 1, coal gas sleeve pipe 2, combustion air intake stack 3, rotation are included
Turnover panel 4, peep-hole 7, fire hole 8, nozzle 9 and flow distribution plate 10, the both sides of nozzle 9 are respectively equipped with peep-hole 7 and fire hole 8, spray
Mouth 9 is connected with coal gas core pipe 1, coal gas sleeve pipe 2 and combustion air intake stack 3 respectively, and the coal gas sleeve pipe 2 is enclosed on coal gas core pipe 1
On, axis direction is provided with flow distribution plate 10 in the combustion air intake stack 3, and flow distribution plate 10 is rotatablely connected with swivel flap 4.
In the present embodiment, coal gas core pipe 1 is connected with thinner gas piping, coal gas sleeve pipe 2 and thicker gas piping
Connection.Coal gas core pipe 1 and coal gas sleeve pipe 2 are put in combustion air intake stack 3 close to one end of nozzle 9, combustion air intake stack 3
By adjusting swivel flap 4 nozzle 9 can be made to produce inner ring wind 5 and outer ring wind 6, inner ring wind 5 is short flame wind, outer ring wind 6 is
Long flame wind.
When calorific value of gas is low, the air-supplying valve in coal gas core pipe 1 and coal gas sleeve pipe 2 is opened；When calorific value of gas is high,
Smaller gas flow is needed, in order to effectively prevent from being tempered, the air-supplying valve of the core pipe that only turns on the gas-fire 1, the supply on coal gas sleeve pipe 2
Valve is closed, even if guarantee calorific value of gas is higher, coal gas burner load reduces, in the case of using small gas flow, coal gas is still
It can so be sprayed according to rational spouting velocity by nozzle end, avoid burner from being tempered；When calorific value of gas is medium, coal gas core pipe 1
Air-supplying valve is closed, the air-supplying valve only to turn on the gas-fire on sleeve pipe 2, can both meet to heat process requirements, while avoid spraying again
Mouth back-fire trouble.
Combustion air intake stack 3 be for nozzle 9 provide combustion air, by adjust swivel flap 4 can control inner ring wind 5 or
Outer ring wind 6 and the two have, so as to according to calorific value of gas height situation, obtain the moderate length of flame, and then meet industry
The demand for heat of stove.In the case of normal combustion, the flame combustion situation of spray can be observed by peep-hole 7.When blow-on is lighted a fire,
Kindling material point burner is introduced by fire hole 8.
