Thermal Radiation from LNG (Liquefied Natural Gas) Trench Fires. Volume 1. Main Report

摘要

The current federal regulations for LNG facilities require a thermal radiation exclusion zone for public safety around spill impoundment systems. The size of this zone is determined by applying a thermal radiation model that was developed for large circular or near circular pool fires. Since trench (elongated pool) fires behave differently from circular pool fires, an experimental test program was conducted to monitor the fire behavior and thermal radiation from large-scale LNG trench fires. The data in general showed that significantly less distance was required according to measurements than what the code specified as a safe separation distance. Based upon the large-scale fire data, a simple model has been developed for predicting radiation fluxes as a function of distance from LNG trench fires.
