    Safety Enclosed Ground Flare System / Smokeless Flare Design Steam Assist Type Burner

     

    Flare System is to handle the discharged combustible gas under the conditions of normal operation, start-up, shut-down and emergencies, which ensure the gas to be flared out instantaneously, safely and reliably and to meet the demand of environmental protection.

     

    Flare System is a kind of safety equipment comprised of pipeline, knock out device, fire retardant equipment, flare burner, ignition system, flare riser and other components.

     

    Flare Categories:

    * Based on the vent gas media’s physical parameters (mainly for toxicity of the vent gas media), discharge pressure, flow rate and so on, the flare shall be divided into two categories – elevated flare and ground flare.

     

    * The elevated flare, based on the support way, shall be divided into self-supported flare, inhaul supported flare and derrick supported flare. The derrick supported flare, based on types of the riser to be fixed, shall be divided into fixed derrick supported flare, demountable derrick supported flare.

     

    * The ground flare, based on vent gas treatment capacity, shall be divided into enclosed ground flare and open ground flare.

     

    * Based on structure of flare burner, the flare shall be divided into steam-assist flare, forced draft assist flare, defused flare, LHV flare, multi-hole collision flare, sonic flare, etc.

     Working principle / flow process

    Ground Flare System: The combustible gas is discharged from production equipment, flows into the battery limit of flare through vent pipe network, flows into the knock-out drum for separation of liquid drops probably contained in vent gas, flows into the water seal drum and breaks through the water seal, and then flows into main gas gathering pipe. Based on the pressure of vent gas inside the main pipe, the control valves on various staged branches are automatically opened to match up the flow rate of flare gas and ensure the burners of corresponding branches to burn smokeless under some higher pressure. The burners corresponding to the staged branches are arranged inside the enclosed chamber or fence, so the flame is invisible from outside. The safety protection devices, such as rupture disks or rupture pin valves etc., are arranged on the bypass of the branches to ensure safety.
