Therefore, in draining water from each of the water tubes 5, water can be caused ... 10/25/07 - 20070245981 - Water heater and method of operating the same A gas water heater device includes a combustion chamber for providing a gas flow, a pipe assembly, and a heat exchanger disposed over the combustion chamber including a plurality of thermal conductors disposed in parallel with each other, each of the plurality of thermal conductors further comprising a base, a ... 09/13/07 - 20070209606 - Heat exchanger and water heater A heat exchanger A1 includes a partition 19 partitioning the space 35 surrounded by a coiled tube 60 at an axially intermediate portion of a housing 2 into a first and a second regions 35a and 35b and partitioning the coiled tube 60 into a first and a second heat ... 04/19/07 - 20070084420 - Instantaneous fuel-fired water heater with low temperature plastic vent structure An instantaneous type fuel-fired water heater has a variable speed blower that discharges combustion air into a fuel burner utilized to heat water flowing through a heat exchanger portion of the water heater. A portion of the air discharged from the blower bypasses the burner and associated heat exchanger, flows ... 04/19/07 - 20070084420 - Instantaneous fuel-fired water heater with low temperature plastic vent structure An instantaneous type fuel-fired water heater has a variable speed blower that discharges combustion air into a fuel burner utilized to heat water flowing through a heat exchanger portion of the water heater. A portion of the air discharged from the blower bypasses the burner and associated heat exchanger, flows ... 04/12/07 - 20070079772 - Fitting for connection of a heat exchanger A device for a fitting for connecting together one or more heat exchangers to a hot water container of the pressure type in the following manner. A connection in the form of a cylindrical pipe with a first end fastened to the wall and/or the hot water container, and a ... 11/30/06 - 20060266305 - Tube assembly for a boiler A boiler is described comprising a housing with a flue gas inlet for receiving a hot gas flame and an outlet for venting a hot gas produced by the hot gas flame, and a tube assembly mounted within the housing. The tube assembly comprises a lower manifold for receiving a ... 11/09/06 - 20060249099 - Compact high efficiency gas fired steam generator-humidifier The high rate internal circulation of boiling water, the extended self cleaning heat transfer surfaces of the flat tubular type heat exchanger immersed in the boiling water, the recovery of latent heat from flue gases and the discharge of cooled solids with cold make up water provide an exceptionally compact ... 09/07/06 - 20060196450 - Condensation heat exchanger with plastic casing The invention concerns a heat exchanger comprising at least one helically bound bundle (2) of tubes, whereof the thermally conductive wall has a flattened and oval cross-section, whereof the main axis is perpendicular to that (X-X′) of the helix, while the width of the interstice separating two adjacent turns is ... ### FreshPatents.com Support |
