Boiler design

A boiler comprising an elongated enclosure;

• said enclosure having a front wall, a rear wall and side walls;
• an upper header and a lower header supported on said enclosure;
• elongated partitions in said enclosure extending from said front wall to a position adjacent said rear wall providing a gas space;
• said elongated partitions having spaces therein;
• said partitions comprising tubes for receiving water;
• said tubes being connected to said upper header and to said lower header;
• said elongated partitions being formed in a generally serpentine shape;
• said generally serpentine shape having bases and crests;
• said crests of each said elongated partition being spaced from a crest of a said elongated partition adjacent thereto;
• each said base of each said elongated partition being disposed between a base of a said elongated partition adjacent thereto whereby combustion chambers are defined between each two adjacent said elongated partitions;
• and
• a burner is disposed in each said combustion chamber.

A boiler comprising an enclosure defined by a front wall, a rear wall, a top, a bottom and side walls;

• individual combustion chambers in said enclosure;
• said combustion chambers extending from said front wall and terminating adjacent said rear wall and providing a gas space between said combustion chambers and said rear wall;
• said combustion chambers being formed of curved partitions;
• said curved partitions comprising boiler tubes supported in side-by-side relation to one another;
• and,
• burners supported on said front wall;
• a said burner disposed in each said combustion chamber;
• an exhaust opening in said top adjacent said front wall;
• said combustion chambers being spaced from said side walls providing a gas space between said combustion chambers and said side walls;
• said combustion chambers providing a path for gas of combustion from said combustion chambers through said space to said exhaust opening;
• an upper header means supported on said top;
• and,
• a lower header means supported on said enclosure below said upper header means.
