- Abstract
- The Federal Code Model for predicting exclusion distances from LNG fires (49 CFR 193.2057) was critically evaluated. The results of LNG fire tests carried out to date were reviewed and an improved model for predicting exclusion distances was developed and verified. This model assumes that the flame takes the shape of a cylinder or a parallellepiped, depending on whether the fuel impoundment area is circular or rectangular in shape. It allows for flame drag and tilt in the presence of wind. Based on experimental data, the maximum surface emissive power and the flame attenuation coefficient were estimated at 190 kw/m2 (60,267 Btu/hr ft2) and 0.3 m-1 (0.09 ft-1), respectively.
