Flame evolution during first second after ignition in a gas stove

摘要

We use an IR camera to record and visualize the ignition process in a domestic gas stove during the first second after the electrical spark has initiated the combustion. The measurement and visualization of the flame growth and distribution process resulted in an improved design of thermo-mechanical properties and ventilation characteristics of the ignition chamber. We report recording and the actual visualization of the real-time ignition process, incorporating frame interpolation and other image processing and subtraction schemes to play back the temporal evolution of the fire-propagation process at a rate suitable for human inspection and visual processing at about 30 frames per second.
