  • Publication number: 20170062690
    Abstract: A thermoelectric generating unit includes a hot-side heat exchanger (HHX) including one or more discrete channels and substantially flat first and second cold-side plates. A first plurality of thermoelectric devices are between the first cold-side plate and a first side of the HHX; and a second plurality of thermoelectric devices can be between the second cold-side plate and a second side of the HHX. Fasteners can extend between the first and second cold-side plates at locations outside of the HHX channel(s). The fasteners can be disposed within gaps between the thermoelectric devices of the first plurality and within gaps between the thermoelectric devices of the second plurality. The fasteners can compress the first plurality of thermoelectric devices between the first cold-side plate and the first side of the HHX and can compress the second plurality of thermoelectric devices between the second cold-side plate and the second side of the HHX.

  • Publication number: 20160099398
    Abstract: A thermoelectric generator includes a tapered inlet manifold including first and second non-parallel sides; first and second pluralities of outlet manifolds; and thermoelectric generating units (TGUs) each including a hot-side heat exchanger (HHX) with inlet and outlet; a cold-side heat exchanger (CHX); and thermoelectric devices arranged between the HHX and CHX. The inlets of some of the HHXs receive exhaust gas from the first side of the tapered inlet manifold and the outlets of those HHXs are coupled to outlet manifolds of the first plurality of outlet manifolds. The inlets of other of the HHXs receive exhaust gas from the second side of the tapered inlet manifold and the outlets of those HHXs are coupled to outlet manifolds of the second plurality of outlet manifolds. The thermoelectric devices can generate electricity responsive to a temperature differential between the exhaust gas and the CHXs.

  • Publication number: 20070057090
    Abstract: A counterflow fuel injection nozzle for injecting fuel is disclosed. The nozzle includes a nozzle wall having an interior surface that defines a nozzle interior, the interior for receiving a fuel therein. The nozzle further has a fuel passageway formed in the nozzle wall for distributing the fuel from the interior to a location exterior of the nozzle, the fuel distributed to the exterior location in a fuel flow injection direction. An airstream is provided in a prevailing air flow direction in the location exterior of the nozzle. At least one vector component of the fuel flow injection direction opposes at least one vector component of the prevailing air flow direction. In this manner, by distributing fuel into an air flow at a counterflow angle, improved control of mixing of the fuel in the air is achieved. The counterflow nozzle may be included as part of a new burner or as a retrofit to existing burners in order to incorporate counterflow mixing.

  • Publication number: 20030091950
    Abstract: An integral industrial burner package has been described. The burner housing includes a blower housing integral to the burner housing for housing a blower motor and fan. Burner components are mounted on the blower housing and are cooled by blower inlet air flowing over the components. The blower output air flows through a collection chamber integral to the housing and into an air conduit formed within the burner housing. A fuel conduit is provided within the air conduit and is connected to a nozzle internal to a combustion chamber where the fuel and air is mixed and ignited.

  • Patent number: 6394795
    Abstract: An air heating burner having improved CO emissions across a broad range of heat inputs. The burner incorporates wings which cover portions of mixing plates associated with low to medium-low fire. The wings reduce air flow velocity to eliminate quenching during such conditions, thereby increasing combustion temperature and reducing CO emissions. The wings also form pre-heat chambers which further increase combustion temperature. The burner produces a substantially consistent level of CO emissions across the range of inputs, regardless of the pressure drop across the burner.
