Enclosed Ground Flare

ENCLOSED GROUND FLARE

 Controlled Emission
 Insulated Design
 Minimal Noise
 Suitable for industries located adjacent to residential areas

Enclosed flare conceals fire on the enclosed wall which is lined up with refractory, thus it has more benefit than open flare. Due to its insulated design, enclosed flare not only offers minimal noise and heat but also reduces radiation.
Characterized by smokeless combustion, the enclosed flare is perfectly suitable for industries located to adjacent to communities.
Enclosed flare burns the unwanted gas from a burner or burners placed above ground and resulting flames are hidden from sight by a surrounding wall or chamber. The top of the chamber is open to the atmosphere and allowance is made at the bottom of the chamber to permit the ingress of combustion air.
Ladder and service platforms may be constructed all the way to the top of the chamber in order to access instrumentations and for stack emissions sampling.
The enclosed flare can achieve higher combustion and destruction efficiencies due to the flare flame being contained in the combustion chamber. Therefore, the design must accurately accounts for the air inflow to the combustion chamber and for the ourflow of hot flue gases from the combustion chamber. The airflow can be either by natural draft or forced draft.
Natural draft airflow is controlled by the use of dampers or other means. This type of enclosed flare normally uses wind fence to mitigate the potential of the wind to upset air and flue gas flows during the combustion process as well as to prevent unauthorized access. In addition, wind fence also offers safety protection for personnel from the radiation of flare flame and from external surfaces of the combustion chamber.
