Abstract:
A scalable pulse combustor that can be deployed as the heat exchanger in high efficiency, low NOx condensing boilers, water heaters and steam generators is provided. The combustor generally comprises an annular burner coil with a burner flange for accommodating the nozzle of a conventional burner/blower fitted into the central aperture thereof; a spaced-apart opposite annular spreader coil with a heat exchange hub fitted into the central aperture thereof; and a plurality of annular intermediate coils. Each of the burner, spreader and intermediate coils are preferably formed of spiral wound stainless steel tubing, with each winding directly abutting the preceding winding so as to create an annular wall. The heat exchange hub functions as a secondary heat exchanger with its own independently controllable coolant flow.

Claim (Index 1):
A scalable pulse combustor for use with a conventional burner, the pulse combustor comprising:\n an annular burner coil or plate with a burner flange for accommodating the conventional burner fitted into a central aperture thereof; a spaced-apart opposite annular spreader coil or plate with a heat exchange hub fitted into a central aperture thereof; and at least one annular intermediate coil or plate located in spaced-apart relationship between and substantially parallel to the burner coil and the spreader coil;\n wherein a combustion chamber is defined between the burner coil or plate and the spreader coil or plate, and a plurality of tailpipe regions are defined on both sides of each of the at least one annular intermediate coils; \n wherein each of the burner, spreader and intermediate coils or plates comprises a coolant passageway for conducting coolant therethrough, and an inlet and outlet for the coolant passageway; and \n wherein the heat exchange hub comprises a coolant passageway for conducting coolant therethrough, and an inlet and outlet for the coolant passageway.
