Heat flux and temperature measurement is carried out on a 2.5m tall 0.15m square steel column exposed to a 0.50 m square porous propane burner. Heat release rate and distance between the column and the burner has been changed systematically. Temperature rise on directly heated surface of the column is found to be restricted due to the conduction through the specimen. Flame heat flux on a steel column adjacent to the wall is represented as a function of height normalized by flame length, while distance between the fire source and the column has a significant influence on the incident heat flux on the steel column. Heat flux at the lower region of the flame is found to be lower than that for in wall flames probably due to the entrainment of ambient air to the flame passing around the column.
