    摘要： A boiler system having a generally cylindrical housing or shell includes a main or fire tube with a furnace or combustion chamber extending longitudinally near the bottom of the housing and a burner to accomplish combustion within the combustion chamber. The combustion chamber opens at its rear end to furnace tube sheet, and to a first set of tubes extending longitudinally of the boiler. The first set of tubes extends to and through the rear tube sheet of the boiler to a turnaround space, which transitions to a second set of tubes located above the combustion chamber and first set of tubes to generally span a length extending from the rear tube sheet of the boiler to the front tube sheet. The boiler system as disclosed has a reduced size while maintaining efficiency in steam and hot water applications.

    摘要： A gas water heater having increased thermal efficiency comprises a water tank having a sealed combustion chamber thereunder. An atmospheric burner is located in the combustion chamber. A flue pipe extends from the sealed combustion chamber and through the water tank for heat exchange of hot atmospheric gas therein with water in the water tank. A heat exchanger is in communication with the combustion gases exiting the water tank to extract residual heat from the combustion gas in the flue pipe for mixture with ambient air to produce pre-heated combustion air. An air convection or draft inducing device directs the hot combustion air from the heat exchanger through a sealed conduit to direct the pre-heated combustion air to the combustion chamber.

    摘要： A high-efficiency hot-water boiler for a heating system of a building is provided. The boiler includes a boiler enclosure that contains a furnace area compartment within an insulated sealed casing, a first watertube compartment within a sealed casing, a second watertube compartment within a sealed casing, and an air-to-air preheat exchanger within a sealed casing. A plurality of separate, closely-spaced watertubes extends within each of the compartments and provides paths for working fluid to flow through the compartments for purposes of transferring heat to the working fluid. A burner is located within the furnace area compartment for combusting an air/gas mixture. The casings include openings for directing the passage of the products of combustion to make a first pass through the furnace area compartment, a second pass through the first watertube compartment and a third pass through the second watertube compartment and then through the air-to-air preheat exchanger to preheat fresh combustion air before being exhausted from the enclosure via the flue. An air/gas mixer and a burner ignition system are also disclosed.

    摘要： A water heater includes a tank 10 arranged inside a casing 20 with a burner 16 below the tank so that a heat exchange zone 15 surrounding the tank receives the combustion products. The tank 10 is supported on three edge contact projections 26 resting on ledges 27 located a substantial distance up the sides of the tank. The casing 20 narrows in the upwards direction and a heat shield 30 is coaxially located in the lower portion of the casing where the hottest gases are. A downwardly extending flue 49 outside the casing provides a heat trap. The burner 15 has a burner ring 60 with a unique arrangement of burner ports 62 and a secondary air guide 80. The thermostat probe 14 for the gas valve 17 passes through the heat exchange zone 15 to be intentionally affected by the heat and reduce the achieved operating temperature differential.
