Radiation from flames of burning Liquefied Natural Gas (LNG) has been measured. The burning pool was contained in a trench. A range of burning rates from 13,500 to 40,000 BBL/D of LNG was studied. Measurements were made from ground level, 300 to 600 ft. from flame center and from several elevated points. Measured flux varied from about 60 to 480 Btu/hr/ft2and was compared to the total flux that would be received at a given distance from flame center if the entire heating value of the fuel were converted to radiant energy. An inverse square law of radiation versus distance was shown to hold fairly well. An average of about 12% of total flux was measured at ground level points fairly independent of distance. Elevated measurements showed an increase in radiation as the interior of the trench was viewed. This raised the average measured flux to about 16% of total.
