    摘要： A gas fired hot water heater includes a housing enclosing an internal chamber divided by a vertical partition into two compartments, the partition having a top edge spaced below the top of the chamber. One of the compartments has a gas burner in the lower portion with an adjacent combustion air intake vent. A first heat exchanger is located in the same compartment above the gas burner but below the top edge of the partition, and a second heat exchanger is located in the other compartment at substantially the same horizontal level as the first. The two heat exchangers are connected in series. Condensate collection means is provided in the other compartment below the second heat exchanger to collect condensate forming on the second heat exchanger and to duct the condensate out of the housing. A flue pipe ducts flue gases from the housing, and a blower is provided to blow the flue gases through the flue pipe. In a particular development, a bimetallic, helically twisted baffle is provided within the straight portions of the central heat exchanger tube, so that temperature swings will cause the bimetallic baffle to expand and contract, thus automatically scouring the internal surface of the tubes, and reducing deposits.

    摘要： A heat exchanger for use with a source of heat in the form of a burner arrangement. The heat exchanger includes a relatively high flow resistance main passage for collecting combustion products from directly above the burner and a low flow resistance secondary passage opening forwardly of the main passage inlet and conveying any combustion products not collected by the main passage relatively directly to the flue. Flue downdraft principally affects flow in the secondary passage. The main passage may include a plurality of chambers to increase the heat exchange surface area. Water condensing in the main passage can be collected and drained to an evaporator rear the burner.

    摘要： A boiler provided with a burner chamber for a burner firing system and a combustion chamber for a solid fuel firing system, both chambers being arranged horizontally side by side in a common boiler water space enclosed by a horizontal outer boiler body. The combustion chamber has an approximately elliptical cross-section with vertical major diameter and the burner chamber has a round cross-section, the longitudinal center lines of both chambers being substantially at the same level. Both chambers are connected at their front ends with two separate horizontal ancillary heating passages extending axially parallel above the chambers within the boiler water space and having rectangular cross-sections with horizontal major cross-sectional dimensions and with internal comb-like ribbings. The outer boiler body is made of a metal sheet shaped in one piece by rolling into a hollow body of non-circular roundish cross-section.
