November 2023, Xi'an Jiahua Thermal Engineering Co., Ltd. is currently installing and commissioning a blast furnace gas ignition and dispersion system at a steel mill in Benxi, Liaoning Province..

The single-pipe blast furnace gas dispersion ignition device can achieve automatic ignition. Upon receiving an ignition signal, it initiates ignition, with the system controlling the ignition device. The ignition control cabinet outputs a successful ignition signal to the remote control. In the event of a flameout signal or detection of a backfire signal, the ignition system can perform nitrogen purging to prevent backfire, meeting effective and safe operational requirements. However, if ignition fails, flameout occurs, or the device itself malfunctions, a fault signal is issued, and safe and proper handling is carried out.
