Problems solved by technology

As a result, the flame is too close to the beam body during combustion, or the flame is trapped in the burner mouth and burns, which is easy to burn the burner mouth and the "T" head of the combustion beam, causing oil leakage and other failures, and is forced to stop for maintenance or replacement unplanned Burning beams will affect normal production and increase equipment investment and maintenance costs

Embodiment 1

[0017] The "T"-shaped combustion beam of the present invention is composed of a beam body 1, in which a fuel pipeline 4 and an air channel 8 are arranged, and burners 2 are arranged on both sides of the beam body, with 10 burners on each side, and the burners include extended Type fuel nozzle 3 and air outlet, the fuel nozzle 3 extends into the burner mouth, and the fuel pipeline is connected to the fuel nozzle. The air outlet is a gap around the fuel nozzle and communicates with the air passage. Two fuel pipelines are arranged in the beam body, and the fuel pipeline is a rectangular box-shaped body structure. The two fuel pipelines are fixedly installed in the air passage with a fixing piece 6, and the fixing piece is supported by a bracket 9. Each fuel pipeline is connected to The fuel nozzle of the burner on the same side, the fuel nozzle is inserted into the burner port. A cavity 5 through which a cooling medium circulates is provided between the inner wall and the outer ...

Embodiment 2

[0020] Another solution of the present invention is as figure 2 As shown, the lower part of the beam body is provided with 10 air nozzles 10 , and the air channel is connected to the air outlet of the burner 2 and the air nozzles 10 . The two fuel pipelines are fixedly installed in the air passage with the fixing piece 6 , and the fixing piece is supported with the bracket 9 . Other structures are the same as in Embodiment 1.

[0021] The supplementary combustion-supporting air sprayed from the air nozzle 10 at the lower part of the combustion beam disperses and flows upward under the suction action of the suction beam at the upper part of the kiln body, and continues to burn with the incompletely burned fuel. To reduce the intensity of fuel combustion at the outlet of the burner and improve the uniformity of the calcined product.

Embodiment 3

[0023] Yet another embodiment of the present invention is as image 3 As shown, the lower part of the beam body is provided with 10 air nozzles 10, and the beam body is divided into upper and lower two air passages 8, 11 by a partition 12. The fuel pipeline 4 passes through the upper air passage 8 and communicates with the air outlet of the burner, and the lower air passage 11 communicates with the air nozzle 10 . Other structures are the same as in Embodiment 1.

[0024] The supplementary combustion-supporting air sprayed from the air nozzle 10 at the lower part of the combustion beam disperses and flows upward under the suction action of the suction beam at the upper part of the kiln body, and continues to burn with the incompletely burned fuel. Control the pressure entering the upper air passage 8 to be lower than the pressure of the lower air passage 11, so that the amount of air ejected from the burner is lower than the theoretical value required for combustion, and the ...

Abstract

The invention provides a T-shaped burning beam, which consists of a beam body. Fuel pipelines and an air channel are arranged in the beam body; two sides of the beam body are provided with burner nozzles, and each side comprises 5 to 20 burner nozzles; each burner nozzle comprises a lengthened fuel nozzle and an air outlet; and the air outlet is a gap around the fuel nozzle. Two fuel pipelines are fixedly arranged in the air channel by fixing elements, and each fuel pipeline is connected with the burner nozzles on the same side. The two fuel pipelines are arranged respectively; and the fuel nozzles are lengthened fuel nozzles and are inserted in burner nozzle mouths so that the fuel is burnt outside the burner nozzles, the flame is far away from the beam body wall, the burner nozzle mouths and a T-shaped head of the burning beam are prevented from being burnt out, the equipment investment and the maintenance cost are saved, and the service life of the burning beam is prolonged.

Description

technical field [0001] The invention belongs to the technical field of combustion equipment, and in particular relates to a T"-shaped combustion beam for a kiln Background technique [0002] Burning limestone in the beam kiln section is a new technology for lime production. The beam type lime kiln has the advantages of low energy consumption, good quality of lime products, strong production capacity, large operating flexibility, etc., and is widely used in lime production for metallurgy, chemical industry and other purposes. The combustion beam is the core equipment of the beam-type lime kiln. The beam body of the combustion beam is equipped with burners, fuel pipelines and combustion-supporting air pipelines. The fuel pipelines and combustion-supporting air pipelines deliver fuel and combustion-supporting air to the burners. to burn. The applicant's patent application number is 200320111077.3, and the utility model patent titled "inside and outside heating type lime furna...
