摘要： A vertical furnace comprising a low NOx gaseous fuel burner comprising:

a primary fuel gas and primary air inlet (24),
a burner array (25) located in a wall (28) of said vertical furnace and connected to said primary air and fuel gas inlet (24) for projecting said primary air and fuel outwardly into said furnace, said primary air and fuel being combusted and producing spent gases,
a plurality of secondary air vents (27) defined in a wall (28) of said furnace for supplying secondary air to said furnace,

摘要： A method and apparatus for reducing NO x emissions in a gas burner in which the burner (1) includes a burner supply for supplying fuel gas and primary air (a) to the furnace and projecting the fuel gas into the furnace, a secondary air supply for supplying secondary air (b) to the burner, and a recirculating device for mixing the secondary air with the spent gases (c) inside the furnace, which is then recirculated and combusted to reduce NO x gases. The method of the invention includes the steps of supplying fuel gas and primary air (a) to the furnace, projecting the fuel gas into the furnace, combusting the fuel gas and primary gas (a) to produce spent gases (c), supplying secondary air (b) to the furnace, mixing the secondary air (b) with the spent gases inside the furnace to produce diluted air (d), and recirculating and combusting the diluted air (d) with the fuel gas and primary air (a) to reduce NO x emissions.

摘要： In a calciner of the type having a screw conveyor for advancing material to and through a calcining reaction zone, and wherein the screw conveyor comprises an internally cooled support shaft 12 which is provided with an outer screw flight shaft 8, an improvement comprising means for controlling the bending stress between the inner and outer shafts is provided. Further, means are also provided for allowing axial movement of one of the shafts relative to the other. The bending stress ranges between the inner and outer shafts are controlled by means of a plurality of bearing members (68) which extend in a generally radial direction with respect to the shafts and which extend between the shafts. The bending stress range is also controlled by the axial position of the bearing members along the shafts. Axial movement of one shaft relative to the other is permitted by the provision of bearing cages 60 around the inner shaft with axial slots 64 formed in the cage. A portion of the bearing member is tracked in the slot and can thus slide axially therein.

摘要： The induction preheating means and methods of the present invention include a furnace for selectively preheating certain portions of irregularly shaped work objects prior to heating to a final uniform temperature in another furnace. The method includes selectively controlling the intensity of the induction magnetic field to provide magnetic field portions of higher intensity adjacent those portions of work objects tending to absorb less energy and magnetic field portions of lower intensity adjacent those portions of the work object tending to absorb energy at a higher rate. The method and means of the present invention are used to achieve substantially uniform temperatures in irregularly shaped work objects after final heating in a main heating furnace.
