Noise Testing and Prediction Methods for Multi-Point Ground Flares

American Flame Research Committee - AFRC 2016 – September 11-14, 2016 – Kauai, Hawaii

Overview:

• Developed in the 1970’s, Multi-Point Ground Flares derive their name from their physical layout.
• Instead of the flare flame being on an elevated structure, the flame is spread out in a grade mounted field of multiple pressure assisted flare tips.
• The tips are then arranged in stages that open as the upstream pressure and gas flow increases and close as pressure and flow decreases

Criteria

• Test setup
• Background noise
• Sound power levels as a function of sonic and subsonic flows
• 10Log vs. 20Log analysis
• Acoustical efficiency
• New gas fuel skids
• Combustion vs. venting
