Description

BACKFIRE PREVENTION TYPE BURNER APPARATUS [0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a back-burner type burner apparatus, and more particularly, to a back-burner type burner apparatus capable of preventing backlash due to air inside a target facility in a state where it is installed in a target facility such as a heating furnace.

Generally, slabs and the like produced through the performance process are loaded into the furnace. For the post-process hot rolling, the heating furnace heats the slab to 1100 ° C to 1300 ° C and is extracted through one side of the furnace.

The slab charged into the heating furnace is heated by a burner installed on the inner wall of the heating furnace. 1 is a view showing a burner 10 installed in a heating furnace 20 in general. 1, the burner 10 includes a fuel pipe 11, an air pipe 12, a center air pipe 13, and a burner nozzle 14, and is installed in the heating furnace 20. The fuel is supplied to the fuel pipe 11 as a mixed gas such as a blast furnace gas (BFG) and a coke oven gas (COG), which are steelmaking by-product gases, and passes through the burner nozzle 14. Further, air is supplied to the air piping 12 to combust the fuel. As a result, a flame is generated, and the generated flame is used to heat the slab. At this time, the center air piping 13 is located at the center of the burner 10, particularly the fuel piping 11. The center air piping 13 is connected to the air piping 13 to reduce SOx, NOx, Supply.

On the other hand, when the amount of fuel is reduced inside the burner, the high-temperature air from the inside of the heating furnace flows into the burner or the fuel pipe along the direction of the arrow shown in FIG. As a result, the air at a high temperature burns the burner and reacts with the fuel inside the fuel pipe to cause an explosion. In addition, since the center air pipe is assembled with the burner nozzle at the end of the burner, the center air pipe is practically not provided at the end adjacent to the inside of the heating furnace. Backfilling due to the air that has flowed into the inside of the burner from the inside of the heating furnace causes various problems such as burner burnout, fire and explosion, but it is difficult to prevent.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

FIG. 2 is a view showing a back fire prevention type burner apparatus 100 according to a preferred embodiment of the present invention, FIG. 3 is a view showing a part of the back fire prevention type burner apparatus 100 shown in FIG. 1, 4 is a perspective view showing a part of the anti-back burner apparatus 100 shown in FIG. 1, and FIG. 5 is a cross-sectional view taken along the line AA in a part of the anti-back burner apparatus 100 shown in FIG. Sectional view.

2 to 5, the backflow prevention type burner apparatus 100 according to the preferred embodiment of the present invention includes a burner unit 101, an air supply unit 102, a temperature sensing unit 103, and a control unit And is used to prevent the backflow of air in the heating furnace 20 from the inside of the burner portion 101 due to the high temperature state. On the other hand, the backflushing type burner apparatus 100 of this embodiment is described as being installed in the heating furnace 20, but it is not limited thereto and can be installed in various facilities for creating a high-temperature atmosphere environment such as an annealing furnace.

The burner unit 101 is installed in the heating furnace 20 and has a tubular shape. The burner unit 101 includes a fuel pipe 111, a center air pipe 113, a fuel valve 115, a burner nozzle 117 and an air pipe 119.

The fuel pipe 111 is supplied with fuel and the fuel is led to the inside of the heating furnace 20 through one end of the fuel pipe 111.

The center air pipe 113 is located along the fuel pipe 111 at the center of the fuel pipe 111 and is supplied with air.

The fuel valve 115 is installed in the fuel pipe 111 and is located outside the heating furnace 20. The fuel valve 115 opens and closes the fuel pipe 111 to control the fuel supply of the fuel pipe 111. That is, when the fuel valve 115 opens the fuel line 111, the fuel can be supplied to the fuel line 111, while when the fuel valve 115 closes the fuel line 111, It can not be supplied to the pipe 111.

The burner nozzle 117 is located at the end of the center air pipe 113 and is located in the fuel pipe 111 adjacent to the inside of the heating furnace 20.

The air pipe 119 surrounds the fuel pipe 111 and is supplied with hot air. Hot air through the air line 119 generates a flame through reaction with the fuel.

Further, in this embodiment, the fuel and air supplied to the burner portion 101 flow from the outside of the heating furnace 20 to the inside thereof. Here, the outside and inside of the heating furnace 20 show left and right sides with reference to the heating furnace 20 shown in Fig.

The air supply unit 102 supplies air to the inside of the fuel pipe 111 from the center air pipe 113. At this time, the supplied air flows toward the inside of the heating furnace 20. The air flows along the direction of the arrows in FIGS. 2 and 3 to guide the fuel inside the fuel pipe 111 to the inside of the heating furnace 20 and to supply the fuel from the inside of the heating furnace 20 to the fuel pipe 111, As shown in FIG. At this time, fuel does not remain in the fuel pipe 111 and air does not flow into the fuel pipe 111, so that no flame is generated and no explosion occurs. The air supply portion 102 includes a main supply pipe 121, supply branch pipes 123, a block portion 125, a supply main portion 127, and a supply valve portion 129.

A part of the main supply pipe 121 is inserted into the center air pipe 113. The outer diameter of the main supply pipe 121 is smaller than the inner diameter of the center air pipe 113. The main supply pipe 121 is supplied with air.

The supply branch pipes 123 are formed in plural and branch from one end of the main supply pipe 121. At this time, the supply branch pipes 123 are located inside the fuel pipe 111. The supply branch pipes 123 are positioned inclined toward the inner surface of the fuel pipe 111 and spaced radially from the main supply pipe 121 at regular intervals. Further, the supply branch pipes 123 pass through the center air pipe 113.

The air is supplied to the main supply pipe 121 through the other end of the main supply pipe 121 and flows into the fuel pipe 111 through the supply branch pipes 123. At this time, the supply branch pipes 123 flow air uniformly along the circumferential direction of the fuel pipe 111 into the fuel pipe 111 and flow toward the inside of the heating furnace 20. Thereby, the fuel can be stably introduced into the interior of the heating furnace 20 from the inside of the fuel pipe 111.

The block portion 125 is located between the main supply pipe 121 and the supply branch pipes 123 and connects the main supply pipe 121 and the supply pipes 123 with each other. The block portion 125 functions as a space for temporarily storing the air that is led from the main supply pipe 121 to the supply branch pipes 123, and buffers in the air flow. At this time, the block portion 125 is located inside the center air supply pipe 113 and is larger than the outer diameter of the main supply pipe 121 and smaller than the inner diameter of the center air pipe 113. The supply branch pipes 123 can be connected to the main supply pipe 121 through the block portion 125 more easily than when the branch pipes 123 are directly connected to the main supply pipe 121.

The main supply pipe 121, the supply branch pipes 123 and the block portion 125 are separated from the inner surface of the center air pipe 113. As a result, air is introduced into the fuel pipe 111 separately from the air flowing through the center air pipe 113. The main supply pipe 121, the supply branch pipes 123 and the block portion 125 do not block the flow of the air flowing through the center air pipe 113 in a state where the main air pipe 113 is installed.

The supply main body 127 is connected to the main supply pipe 121 to supply air to the main supply pipe 121. At this time, the supply main body 127 is connected to the other end of the main supply pipe 121. The supply main body portion 127 includes an air storage portion 127a, an air line portion 127b, an air induction portion 127c, and an air conditioning portion 127d.

The air storage part 127a stores air and the air line part 127b extends from the air storage part 127a and is connected to the other end of the main supply pipe 121. [ That is, the air stored in the air storage part 127a flows along the air line part 127b and can be supplied to the main supply pipe 121.

The air induction part 127c is installed in the air storage part 127a to allow the air stored in the air storage part 127a to flow along the air line part 127b. At this time, the air induction unit 127c is made up of a combination of a compressor, a motor, and the like.

The air conditioning part 127d is provided on the air line part 127b and adjusts the pressure of air introduced into the main supply pipe 121 through the air line part 127b. As a result, the main supply pipe 121 is supplied with air at a set pressure level.

For example, in order to allow the air stored in the air storage portion 127a to flow into the interior of the fuel pipe 111 through the main supply pipe 121 and the supply branch pipe 123 along the air line portion 127b , And the air induction unit 127c maintains the air pressure in the air storage unit 127a at 5 kg / cm2 to 7 kg / cm2. The air supplied to the main supply pipe 121 flows into the interior of the fuel pipe 111 to guide the fuel remaining in the fuel pipe 111 to the inside of the heating furnace 20, (127d) regulates the pressure of air in the air line portion (127b). Generally, air flows into the main supply pipe 121 at a pressure of 0.4 kg / cm 2 to 0.5 kg / cm 2.

The supply valve portion 129 is located between the main supply pipe 121 and the supply main portion 127 and particularly the air line portion 127b and opens and closes between the main supply pipe 121 and the air line portion 127b. Therefore, the supply valve portion 129 is used to determine whether or not air is supplied to the main supply pipe 121 and the supply branch pipes 123. That is, when the supply valve portion 115 opens between the main supply pipe 121 and the supply main portion 127, the air can be supplied to the main supply pipe 121 while the supply valve portion 129 is connected to the main supply pipe 121 121 and the supply main body part 127, the air can not be supplied to the main supply pipe 121.

The air supply unit 102 having the above configuration supplies air inside the fuel pipe 111 to guide the fuel inside the fuel pipe 111 to the inside of the heating furnace 20, Thereby preventing the internal air from flowing into the fuel pipe 111. At this time, the fuel flowing by the air flows in the direction I shown in FIGS. 2 and 3 and is guided to the inside of the heating furnace 20, and the internal air of the heating furnace 20 flows from the inside of the fuel pipe 111 In the direction B shown in FIG. 3 by the air of the fuel pipe 111 and does not flow into the fuel pipe 111. As a result, backfire can be prevented in the burner portion 101 due to the internal air of the heating furnace 20.

The temperature sensing unit 103 is installed inside the fuel pipe 111 to sense the internal temperature of the fuel pipe 111. The temperature sensing unit 103 is used to check whether or not the high-temperature air flows from the inside of the heating furnace 20 into the interior of the fuel pipe 111. Generally, as the air flows into the interior of the fuel pipe 111 from the inside of the heating furnace 20, the internal temperature of the fuel pipe 111 increases. Therefore, when the temperature sensing unit 103 senses the internal temperature of the fuel pipe 111 at a predetermined temperature value, it senses that the air has flowed into the fuel pipe 111 from the inside of the heating furnace 20. Here, the predetermined temperature value of the internal temperature of the fuel pipe 111 is preferably set to about 500 캜. At this time, the burner unit 101 may be deformed or damaged by the air introduced from the inside of the heating furnace 20 at the above temperature.

On the other hand, when the high temperature air does not flow smoothly into the heating furnace 20 through the air piping 119 or when the fuel does not flow smoothly into the fuel piping 111, May flow into the fuel pipe 111 and backfire may occur. Particularly, explosion may occur in the fuel pipe 111. Therefore, the temperature sensing unit 103 is installed in the fuel pipe 111 so that the inflow of air from the inside of the heating furnace 20 can be sensed to the fuel pipe 111, which may cause explosion.

The control unit 104 is located outside the heating furnace 20 and connected to the temperature sensing unit 103 and the supply valve unit 129 of the air supply unit 102 and the fuel valve 115 of the burner unit 101, Lt; / RTI > At this time, the control unit 104 controls the supply valve unit 129 and the fuel valve 115 according to the temperature sensed by the temperature sensing unit 103.

When the temperature sensing unit 103 senses the internal temperature of the fuel pipe 111 at or above the predetermined temperature value, the control unit 104 opens the supply valve unit 129 and closes the fuel valve 115. As a result, fuel is not supplied to the inside of the fuel pipe 111, but air is supplied. At this time, the air can be used to guide the fuel remaining in the fuel pipe 111 to the inside of the heating furnace 20 to prevent backfire in the fuel pipe 111.

On the other hand, when the temperature sensing unit 103 senses the internal temperature of the fuel pipe 111 below the predetermined temperature value, the control unit 104 closes the supply valve unit 129 and opens the fuel valve 115 . As a result, the fuel is continuously supplied into the fuel pipe 111, so that the fuel can be used to be burned while being led into the heating furnace 20.

Therefore, the backflow prevention type burner apparatus 100 according to the present embodiment uses a combination of the temperature sensing unit 103 and the control unit 104 to control the temperature of the fuel piping 111 using the air supply unit 102 111 can be controlled. That is, the air supply unit 102 supplies air to the inside of the fuel pipe 111 according to the temperature of the fuel pipe 111, and transfers the fuel remaining in the fuel pipe 111 to the inside of the heating furnace 20 So that backfire can be prevented.

The back fire prevention type burner hood 100 according to the present embodiment prevents backburning in the burner portion 101 to damage the burner portion 101 and to prevent the fuel and the inside of the heating furnace 20 It is possible to prevent the explosion and the fire caused by the reaction of the air, and the interruption of the operation due to the damage of the heating furnace 20 accordingly.

While the present invention has been described in connection with certain exemplary embodiments, it will be understood by those skilled in the art that various changes may be made without departing from the scope of the present invention.
