This study aims to determine several key parameters of a liquefied natural gas (LNG) pool fire on land through a field test. The mass burning rate was 0.186 kg/(m² s) using the thermocouple method. Through the analysis of high-speed camera images, puffing frequencies of 0.53 and 0.69 Hz were determined for two consecutive oscillations of the flame. The flame tilt was found to be 58°, and the flame length was estimated as 25.4 m. The flame velocity field was first studied for an LNG field test using a high-speed camera, and the maximum velocity was approximately 6 m/s at the center of the flame. The solid flame model predicted well the thermal radiation at both downwind and crosswind directions, using surface emissive power recommended by the Federal Energy Regulatory Commission. Also, new correlations were developed for mass burning rate, flame length, and tilt against experimental results summarized in this work.
