Abstract:

Knowing fire temperature and soot concentration in a fire is very important in fire safety research. The fire radiant energy, a function of fire temperature and soot concentration, contributes about 40% of energy loss to the walls of the Ohio State University (OSU) fire calorimeter during the burning of large area cabin materials. This report presents a method to measure the full field of flame temperature and soot volume fraction in fire using a digital camera. The report also outlines a new procedure to simultaneously calibrate and characterize the camera's detector using a blackbody furnace. The developed methods are implemented to measure flame temperature and soot volume fraction in a liquid-fueled steady laminar diffusion flame, impacted by the phosphorus type flame-retardant material. The flame-retardant material is found to promote soot formation and suppress soot oxidation in the fire. The increased net soot concentration cools the flame, resulting in incomplete combustion.
