DEVICE FOR PREVENTION OF SCALING Russian patent published in 2003 - IPC

Abstract RU 2206854 C1

FIELD: heat engineering, applicable for prevention of scaling in boilers. SUBSTANCE: the device has a yoke attached at the end of the waveguide, the yoke cavity has a circular race rolled by a ball and a nozzle for supply of compressed air, the nozzle outlets are made contracting, and then expanding (tapered), the exit apex angle of the nozzle makes up 11-12 deg. EFFECT: enhanced efficiency of device operation due to expansion of the upper boundary of frequency and amplitude of the excited vibrations and expansion of the functional abilities. 1 dwg
