Flares are important safety devices used in refineries and petrochemical facilities. They safely burn excess hydrocarbon gases which cannot be recovered or recycled. Excess hydrocarbon gases are burnt in the flare systems in an environmentally-sound manner, as an alternative to releasing the vapour directly into the atmosphere. The Smokeless Flare Stack is a comprehensive flare device which integrates the high pressure electronic ignition and gas combustion function. By the ignition control box, an ignition device and the torch three major components. The connection between the ignition control box and the ignition device adopts high voltage wire, external install protective tube and explosion-proof hose.
