Heat Transfer to and Ignition of Ceiling by an Impinging Diffusion Flame

摘要

The work is an experimental study of the heat transfer to and the ignition of a ceiling surface exposed by an impinging buoyant jet diffusion flame. Natural gas flames in the range of 2.9 kW to 10.5 kW on a burner of a diameter of 64 mm were used. The shapes of these flames are described with appropriate temperature and species concentration measurements. (Copyright (c) Valtion teknillinen tutkimuskeskus (VTT) 1989).
