Abstract
An apparatus and method by which deposits are removed from the heat exchange surfaces of heat exchange element in a boiler. According to the present invention, a heat exchange medium flowing through the element at a first temperature has injected into it a fluid at a second temperature. The injection of the fluid and the temperature difference between the fluid and the medium causes a pressure wave to be produced in the heat exchange element at a specific location whereby the pressure wave in the medium causes mechanical vibration of the element. The result is that ash, scale, soot and other deposits are fractured, loosened and removed from the surfaces of the element.
