摘要： A method and apparatus for recovering water from a heated gas mixture. The heated gas mixture is passed across one or more heat pipe heat exchangers connected in series. Each heat pipe heat exchanger includes an upper chamber separated from a lower chamber, and sealed heat pipes extending between the chambers. The heated gas mixture is passed across the lower chamber, where the heated gas mixture is cooled with the plurality of heat pipes, passing heat into the heat pipe fluid and thereby condensing water vapor to liquid water on an outside of the of heat pipes. Ambient air or other gas of a cooling temperature is passed across the upper chamber to reduce the heated temperature controlled fluid inside the plurality of heat pipes.

摘要： An apparatus and method for producing heat and electricity independent of an electrical grid. The apparatus includes a burner adapted to produce at least one of radiant heat, flame and hot combustion gases. A thermal-to-electric conversion device is integrated with the burner and proximate to the burner, for producing electricity. The conversion device has a first side disposed toward the at least one of radiant heat, flame and hot combustion gases and a second side disposed toward and in heat transfer contact with a liquid supply line. The apparatus is useful in water heaters. The liquid supply line provides both water to be heated and a cooling medium for the thermal-to-electric conversion device.

摘要： Methods and combustion devices for reducing NOx formation upon combusting oxidant with fuel to form products of combustion are provided. Such methods and device may involve mixing at least first portions of at least two fluids selected from the group of oxidant, fuel and recirculated products of combustion in at least one first conduit to form a first mixture. The first mixture is subsequently supplied to a plurality of second conduits each in direct fluid communication with the first conduit. Motive energy is utilized to aspirate at least second portions of one or more fluids selected from the group of oxidant, fuel and recirculated products of combustion in at least one second conduit to form a combustible mixture that can be subsequently burned. In one embodiment, the motive energy may be provided or result from the first mixture.
