  • Controlled Emission

  • Insulated Design For Lower Heat Radiation

  • Minimum Noise Level

  • Suitable for industries located adjacent to residential areas

Enclosed ground flare provides a very cost effective solution for the smokeless invisible flaring of many combustible gases. Enclosed flare conceals fire in the enclosed wall which are lined up with refractory, which is definitely more beneficial than open flare. Due to its insulated design, enclosed flare not only offers minimum noise but also reduces
thermal radiation efficiently.

Characterized by smokeless combustion, the enclosed flare is perfectly suitable for areas adjacent to residences or critical operation / production facilities. Enclosed flare burns unwanted gas by a configuration of burners which are placed at ground section of the flare. Flames are hidden by the surrounding wall. Ladder and service plat forms may be constructed all the way to the top of the chamber in order to have access on instrumentation and emissions sampling equipment.

The enclosed flare can achieve higher destruction efficiencies due to the combustion reaction between excess air / gas, which takes place in the combustion chamber. Therefore, the design must accurately account for the height of flare and the supply of excess air for combustion. The supply of excess air can be either by natural draft or forced draft.  Natural draft is controlled by dampers or louvers. This type of enclosed flare normally uses wind fence to mitigate the potential of the wind to interfere with 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.

Meanwhile, forced draft utilizes the blowers. During the operation, the combustion temperature is monitored and controlled by means of louvers opening and/or blower speed.
