Abstract
A water or fluid-cooled device consists of a plurality of exhaust tubes of uniform cross-section, similar to the tubes in a boiler. The tubes are connected to an elongate combustion chamber into which a combustible mixture is aspirated via one or a series a non-return valves. The fuel is initially ignited, and subsequently follows the conventional pattern for pulsating combustion. This pulsating combustion burner can be used as an instrument for making a series of shockwaves at a frequency of oscillation between 200 and 2000 Hz, and thus can be used in the conditioning of fine dust particles by agglomerating them. An alternate use is that of a burner for a boiler or a space heater, where suitable action is taken to silence the exhaust noise, and where the scrubbing action of the generated shockwaves inside the exhaust tubes improves the heat transfer to the surrounding medium by minimizing the laminar surface film or 'stagnant layer' inside and outside the exhaust tubes.
