Compact pulse combustion burner with enhanced heat transfer
This patent describes a pulse combustion burner. This burner consists of a combustion chamber, inlet means for admitting a combustible gaseous mixture into the chamber and restricting reverse flow therethrough, means for igniting the gaseous mixture, a wall forming the combustion chamber, the combustion chamber wall having a multitude of spaced apertures. The combustion chamber wall restricts the flow of gases from the combustion chamber to passage through the apertures. A heat exchanger wall spaced from the combustion chamber wall and forming therewith passage means for receiving gases passing through the apertures. An exhaust conduit of predetermined cross section in communication with the passage is for receiving gases passing through the apertures. The collective area of the apertures is generally matched to the cross-sectional area of the exhaust conduit. The heat exchanger wall has a heat transfer surface arranged in close proximity to the path of combustion products passing through the apertures.
