Research Abstract |
In order to burn stably and continuously in a lean combustion limit (such low fuel concentration that a flame usually disappears) under various air current temperature, the ultrasonic wave effects by two different frequencies were utilized to the flame. As a result, when two systems were applied simultaneously, the stability limit expands which is not obtained in one system. However, since the ultrasound effect was decreased by factors, such as interference of the sound of two systems, it is required that the sound pressure level (the amplitude of vibration) is increased.
