Natural gas burners are used in forging heating furnaces, which can shorten the heating time of forgings, speed up the temperature of the cold furnace, and evenly heat, save fuel... Why can so many benefits be realized? Below Yinuo will decrypt it for you.

Application of natural gas burner in forging heating furnace

1. Centrifugal effect and wall effect

The natural gas burner uses the centrifugal effect and the wall effect of the rotating airflow to make the flame adhere to the furnace wall without forward momentum. The kinetic energy of the outlet is converted to radial ejection by the guiding action of the burner brick, and the outlet of the burner becomes the center of the circle. Disc-shaped flame.

In the disc, it has a high negative pressure due to centrifugal effect, and the furnace gas is sucked into the disc at a high speed, so that the furnace gas is continuously circulated and stirred. The flowing nature of the natural gas flat flame burner flame gives the forging heating furnace many unique properties.

The high-temperature disc-shaped flame and the high-temperature furnace gas at the end of the flame are attached to the furnace wall and flow, which improves the heat transfer of the furnace gas to the furnace wall, thereby increasing the radiation capacity of the furnace wall. The uniformly flowing high-temperature furnace gas turns to the furnace bottom along the furnace wall, which improves the convective heat transfer to the material on the furnace bottom. Due to the strong circulation of furnace gas, the temperature of the furnace is even.

2. Application on other stoves

Not only for forging heating furnaces, but when used on gas heat treatment furnaces, it can reduce the temperature difference between the top and bottom of the furnace, and improve the quality of the heat treatment furnace; when used on continuous steel rolling furnaces, it can improve furnace pressure distribution and reduce or even avoid discharge ports. Inhale cold air. The end wall of the furnace is moved closer to the tapping port to reduce the space area, so that the continuous steel rolling furnace can reduce oxidation burning loss and reduce energy consumption. If the burner is installed on the top of the furnace, the height of the furnace can be reduced to reduce heat loss.
