Abstract:
Known chimneys or chimney furnaces use flue gas flow units for heating buildings, said devices having displaceable or fixed obstacles for deflecting flue gas for generating flue gas turbulence. The invention relates to a device and method for transferring heat through a flue gas discharge pipe (28) in which (44, 45) pivotal guide plates (37) are inserted in the longitudinal direction of the pipe run, at which the flue gas flow (22) is more or less deflected in a sinuous line as a function of the pivot angle (24) of the guide plates (37) that can be adjusted during furnace operation. A fan (19) can increase the flue gas flow (22). An optional furnace heat exchanger (29) generates additional hot water as needed. The controller (5) activates the actuators for the fan (19), guide plate pivot angle setting (24), and at least one circulating pump (10 or 11) as a function of the prescribed controlled variables such as flue gas temperature, reservoir temperature, heat exchanger performance, or flue gas flow.
Abstract:
A novel water heat exchanger with a helix coil incorporated into an elongated variable diameter cylindrical housing. A buffer tank is incorporated within the lumen of the helix coil. The heat exchanger utilizes a radial direct-firing burner and a blower-driven hot flue gas to heat water. At least a rope seal is disposed between adjacent coil loops of a portion of the helix coil for enhancing heat transfer to the helix coil. In one embodiment, solar and electric heating systems are combined with the helix coil heat exchanger to provide supplemental heating. In another embodiment, the heat exchanger further comprises a Stirling engine comprised of a free piston having hot and cold ends, wherein the hot end receives heat from the burner and the cold end is cooled by the incoming cold water line to form an electric power generator.
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.

Abstract:
A method of producing a heat exchanger having a hollow elongated member (3) for conducting a liquid, and coiled about an axis (A) to form a number of adjacent turns (13) and a gap of predetermined size between the adjacent turns (13). The method includes the steps of coiling the hollow elongated member (3) about the axis (A) with such a coil pitch that the adjacent turns (13) either contact one another or are spaced apart by a distance smaller than the predetermined size of the gap; and inserting spacers between the adjacent turns (13); the spacers being designed to define the predetermined size of the gap, and to generate in the coiled hollow elongated member (3) a compressive force (F) along the axis (A).
