RADIATIVE HEAT TRANSFER FROM WALL FLAMES.

Abstract

Measurements of radiative and total heat transfer from flames to wall are presented for combustion of propane, methane, and natural gas. The radiative heat feedback from flames to the wall was determined from measurements using a narrow angle radiometer. The radiative fraction of the total heat feedback was found to be almost independent of the burner power output when plotted against scaled height. Flame radiation increased slightly with height or remained constant depending on the fuel, as long as the flames continuously covered the wall; above this height, it dropped rapidly with height. Among the three fuels tested, radiative fraction in flame-to-wall heat transfer was the maximum for propane and minimum for methane, which can be explained based on sooting characteristics of flames. The total radiative energy transfer as a fraction of the burner output power is also presented for the three fuels.
