AI Technical Summary

Technical Problem

The flame of the blast furnace gas venting tower is easily affected by the sideflow, causing the flame to deflect downwards and disperse towards the leeward side. It is also prone to extinguishing or detaching during high-flow venting, affecting the stability and service life of the accessories.

Method used

A blast furnace gas venting tower flare head was designed, which includes an ignition rod, a gas-supporting pipe, a windproof cover, and a swirl device. The swirl device increases air mixing and forms a rotating bundle of gas columns, which improves combustion stability and flame rigidity, and prevents flameout and damage to accessories.

Benefits of technology

It achieves stable blast furnace gas combustion and enhanced flame rigidity, avoiding flameout and accessory burnout, and adapting to extreme weather conditions.
