摘要： Method and apparatus of producing gas pressure pulses in a dust-deposit cleaning apparatus. The apparatus comprises a combustion chamber and an amplifying horn. According to the method a combustible gas and oxygen is fed into the combustion chamber, which has a generally elongated shape, the gas mixture is ignited for generating a pressure pulse, and the pressure pulse is released from the chamber and conducted to the amplifying horn. The gas mixture is ignited to generate an initial explosion which causes a pressure wave, which is reflected from the inner walls of the chamber end to form a collision zone, in which the initial explosion is at least partially transformed into a detonation. The combustion front is reflected from the gas inlet end and compressed at the other end of the chamber and released to the amplifying horn. By means of the invention, sound levels of about 165-170 dB can be produced at low fuel consumption.
