HEAT EXCHANGER

PROBLEM TO BE SOLVED: To solve a problem on the generation of air column resonance noise caused by the resonance of Karman vortex released from a group of tubes and a duct (casing) of a heat recovering device, when a group of heat exchange tubes exists in the flow of a combustion gas. SOLUTION: In t...

Zusammenfassung:	PROBLEM TO BE SOLVED: To solve a problem on the generation of air column resonance noise caused by the resonance of Karman vortex released from a group of tubes and a duct (casing) of a heat recovering device, when a group of heat exchange tubes exists in the flow of a combustion gas. SOLUTION: In this heat exchanger, a heat transfer tube with a fin, provided with a metallic wire spirally fixed on its outer periphery, is mounted in a heat exchange chamber.
