VIBRATORY SCALE REDUCTION IN HOT WATER HEATERS, STEAM GENERATORS AND RELATED DEVICES

摘要

A steam generator for generating steam by boiling water, or other hot water heating device, in either case such as for use in a steam cooker or warewasher, includes a tank structure providing a heating chamber for holding water and including a water inlet, a steam outlet and a water drain outlet. A heating element is located for heating water within the heating chamber so as to generate steam. At least one transducer is located on or within the tank structure to cause water within the heating chamber to vibrate so as to reduce scale build-up on one or more surfaces within the heating chamber.
