Abstract

A sound generating system, suitable among other purposes for keeping boilers and the like free of soot, comprises a sound generator (13), for example a rotary sound generator, which functions by interrupting an air or gas supply at predetermined frequent intervals, at least one resonance tube (18, 19, 20) connected to receive sound pulses produced by the sound generator (13), and, disposed in the connecting line between the sound generator (13) and the or each resonance tube (18, 19, 20), a valve (21, 22, 23) having a straight-through flow passage closable by rotation of a rotary valve member. The system makes it possible to operate several such resonance tubes (18, 19, 20) from a single sound generator (13).
