Noise Testing and Prediction Methods for Multipoint Ground Flares

Noise Testing and Prediction Methods for Multipoint Ground Flares

With increasing demand for multipoint ground flares both domestically and internationally, noise generation from flares has become a focal point of discussion. Currently, there are no set industry standards for noise predictions and theoretical noise values, which often vary between flare suppliers.

Over the years, Zeeco has conducted numerous noise measurement tests on multipoint flares. This paper will cover the testing and test results obtained in conjunction with one of the foremost noise consultants in the industry. In addition, this paper will address in detail noise generation from various gases at multiple sonic and sub-sonic flow rates. Further information and analysis will be provided to discuss the impact of jet noise vs. combustion noise, as well as calculating noise at various distances.

Zeeco hopes to set standards within the combustion industry in regards to predicting noise for multipoint ground flares based on the relationships correlated from the test data.
