Embodiment Construction

[0017] For a better understanding of the present invention, the technical solutions of the present invention will be further described below in conjunction with the embodiments and accompanying drawings, see Figure 1 to Figure 5 :

[0018] According to the flat flame burner with automatic ignition and flame detection device implemented in the present invention, it mainly includes burner brick 1, air pipe shell 6, gas pipe shell 8, gas core pipe 5, air distribution plate 4, gas nozzle Flame stabilizer 3.

[0019] The burner brick 1 is a cylinder with a horn-shaped spout, placed horizontally. The anchor nails are welded on the fixed plate at the tail, and the burner brick is molded with castable materials. The long-term use temperature is 1350 ° C, and the highest temperature resistance level can reach 1600 ° C. The diameter and length of the inlet and outlet of the burner brick 1 are formed according to the burner power and the flat flame. Calculation and determination of th...

Abstract

The invention relates to the technical field of metallurgy, in particular to a flat-flame nozzle with an automatic ignition and flame detection device. The flat-flame nozzle with the automatic ignition and flame detection device comprises nozzle bricks, wherein the nozzle bricks are connected with an air pipeline shell; the air pipeline shell is connected with a gas pipeline shell; gas core tubes are extended into spray orifices in the nozzle bricks and are fixedly welded with a gas nozzle flame holder; an air distribution plate is sleeved on the gas nozzle flame holder; an air inlet is formed on the air pipeline shell and is connected with an air pipeline; the gas pipeline shell is connected to a gas pipeline; electrodes are plugged into two electrode holes and electrically connected with a flyback transformer, and the flyback transformer is electrically connected with a controller; and the electrodes are electrically connected to a detection port of the controller, and an electromagnetic valve of the gas pipeline is electrically connected with the controller. By adding the functions of automatic ignition and flame detection, on-off control is realized, and pulse control is realized for a burning system with the flat-flame nozzle; stable and explanate flame is formed, so that the uniformity of temperature of a hearth is ensured; and therefore, the flat-flame nozzle is simple and compact in structure and can be widely applied.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a novel combustion device with an automatic ignition and flame detection device applied to heating furnaces and heat treatment furnaces. Background technique [0002] Flat flame combustion technology is a new, efficient and clean combustion technology developed on the basis of strong swirling jet combustion technology. Since its appearance in the 1960s, it has been widely used in the industrial sector, especially in the metallurgical industry. The flame ejected from the flat flame burner is a disc-shaped thin layer extending around the furnace wall, which forms a flat flame with an opening angle of 180°. Compared with ordinary straight flame burners, flat flame burners have better flame stability, uniform flame temperature distribution, NO 1 , NO 2 It has a series of advantages such as less emission, fast heating of the workpiece, and anti-oxidation. It is mainly used in in...
