Patent number: 9291401Abstract: A condensing heat exchange economizer wherein upwardly flowing hot flue gas is apportioned by a damper among a plurality of reverse flow passages and redirected to flow in a downward direction through the reverse flow passages over respective bundles of heat exchange tubes carrying a counter-flowing heat exchange medium to form condensate and cool the flue gas. The economizer may comprise a housing having a main flow duct defining a main flow passage in which the damper is located, a pair of conduits opposing one another across the main flow duct and defining respective reverse flow passages, and a pair of return channels opposing one another across the main flow duct and defining respective return flow passages. The cooled flue gas may be merged with the main flow passage at a location above the damper.Type: GrantFiled: February 24, 2014Date of Patent: March 22, 2016Assignee: COMBUSTION & ENERGY SYSTEMS LTD.Inventor: Daniel H. Veitch

Patent number: 4389980Abstract: A boiler has a chamber to contain a charge of wood that rests on the bottom of the chamber with the major portion of the charge within a water jacketed upper portion of the chamber but free to settle as combustion progresses. Combustion is confined to the bottom portion of the chamber due to the cooling effect of the water jacket and to a turbulent cross draft in the combustion zone. A special venturi section in the flue coupled with a pressure blower both induces the flow of hot gases from the combustion zone through a second chamber and a heat exchanger and also provides a stream of air from the venturi section to create the cross draft. An oil burner may be used in conjunction with the second chamber as an alternate heat source. The boiler also has a special base construction and assembly features.Type: GrantFiled: October 21, 1980Date of Patent: June 28, 1983Assignee: Dumont IndustriesInventors: Richard P. Marcotte, John W. Dumont, Jr.
