Abstract
The utility model is related to a kind of injection type mixed gas tundish burner, including combustion chamber, gas three-way and combustion tube, the lower end of the gas three-way passes through the upper end cover of combustion chamber, the bypass of gas three-way to be connect with gaspipe line；The upper end of the combustion tube passes through the bottom end cover of combustion chamber, and lower end passes through a burn-out-proof lid, and is directed toward tundish；The upper end cover of gas three-way is also associated with a compressed air hose, compressed air hose through gas three-way upper end cover and stretch to positioned at the lower face for the indoor stabilizer that burns, in combustion chamber upper end setting there are one igniter devices.The utility model supplements a part of combustion air to combustion chamber automatically and burns using the jet-action of compressed air high speed and the two-way jeting effect of gaspipe line coal gas.The tundish burner has the features such as flame rigidity is strong, burn-out-proof is durable, heating rate, saving energy consumption.
Description
Technical field
The utility model belongs to roasting plant technical field, and in particular to a kind of injection type mixed gas tundish burning
Device.
Background technology
In iron and steel enterprise, the baking of tundish device of continuous casting in use, often due to the pressure oscillation of coal gas, heat
The fluctuation of value.It causes combustion efficiency bad, the coal gas of 1600 kilocalories is more than especially for calorific value, tundish burner often holds
The rigidity of easy burn-out, flame is not strong.
Invention content
Used technical solution is to provide a kind of injection type mixed gas to the utility model to solve above-mentioned technical problem
Tundish burner, including combustion chamber, gas three-way and combustion tube, the lower end of the gas three-way pass through the upper end of combustion chamber
Lid, the bypass of gas three-way are connect with gaspipe line；The upper end of combustion tube passes through the bottom end cover of combustion chamber, lower end to pass through one to prevent
Lid is burnt, and is directed toward tundish；The upper end cover of gas three-way is also associated with a compressed air hose, and compressed air hose runs through coal gas three
Logical upper end cover is simultaneously stretched to positioned at the lower face for the indoor stabilizer that burns, in combustion chamber upper end setting there are one igniters to fill
It sets.
Further, it is equipped with air inducing hole in combustion chamber tube wall.
Further, it is equipped with support stick in stabilizer bottom.
Further, burn-out-proof lid is made of outer barrel, upper cover plate, skirtboard, refractory material, and the refractory material is resistance to containing zirconium
Guncotton or refractory cement castable.
The dual jeting effect that the utility model is formed using compressed air high speed injection with gaspipe line gas injection, from
It moves and burns to combustion chamber a part of combustion air of supplement.Play the role of cooling to combustion chamber simultaneously, extends and use
Service life.The tundish burner is strong with flame rigidity, burn-out-proof is durable, and heating rate is fast, saves the features such as energy consumption.
Description of the drawings
Fig. 1 is a kind of injection type mixed gas tundish burner structure schematic diagram.
In figure, 1, gas three-way, 2, compressed air hose, 3, support stick, 4, combustion tube, 5, refractory material, 6, stabilizer, 7,
Air inducing hole, 8, burn-out-proof lid, 9, combustion chamber, 10, igniter.
Specific implementation mode
The utility model is further described below in conjunction with attached drawing and specific embodiment.
As shown in Figure 1, being a kind of injection type mixed gas tundish burner structure schematic diagram.Including combustion chamber 9, coal gas
Threeway 1 and combustion tube 4, the lower end of gas three-way 1 pass through the upper end cover of combustion chamber 9, the coal gas of the bypass and branch of gas three-way 1
Piping connection；The upper end of combustion tube 4 passes through the bottom end cover of combustion chamber 9, and lower end passes through burn-out-proof lid 9, and is directed toward tundish.Coal gas three
Logical 1 upper end cover is also associated with a compressed air hose 2, and compressed air hose 2 runs through the upper end cover of gas three-way 1 and stretches to and is located at
The lower face of stabilizer 6 in combustion chamber 9.9 tube wall is equipped with the air inducing hole 7 for automatic air draught, and combustion chamber 9 in combustion chamber
Igniter 10 is provided on upper end cover.
Burn-out-proof lid is made of outer barrel, upper cover plate, skirtboard, refractory material 5, and refractory material uses refractory cotton containing zirconium or fire resisting water
Mud castable.
There are several support sticks 3 in 6 lower end of stabilizer, be both to 6 fixed effect of stabilizer, and for reply calorific value of gas
Fluctuation, anti-extinguishing fire action.
Compressed air line 2, gaspipe line etc. are connected with form of flanges, facilitate the replacement of burner.
The utility model is automatic to combustion using the jet-action of compressed air high speed and the two-way jeting effect of gaspipe line coal gas
Room a part of combustion air of supplement is burnt to burn.The tundish burner is strong with flame rigidity, burn-out-proof is durable, heating speed
Degree saves the features such as energy consumption.
