HEAT-EXCHANGER, COMBUSTION DEVICE AND ITS CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To improve performance by effectively applying a sound wave on the internal part of a heat exchanger. SOLUTION: A combustion device comprises a sound wave generating device 10 to apply vibration on fluid 6 flowing through a casing 5; a sound pressure converter 11 to detect a sound fluctuation at the internal part of the casing; and a sound wave control device 14 enabling regulation of the amplitude, the frequency, and the phase of a sound pressure, based on a sound pressure fluctuation detected by the sound pressure detector. The sound wave generating device is operated by the control signal of the sound wave control device.
