Abstract: An apparatus and method are provided for reducing NO.sub.x production during combustion in an tangential burner. Air nozzles are arranged tangentially to a fuel/air nozzle and are tilted relative to the fuel air nozzle. Upon operation, spaces are formed between the air flow and the fuel flow which entrain laterally combustion gases thereby delaying mixing of the air and fuel flows. By this delay, NO.sub.x production is reduced.

Abstract: Horizontally arranged burners for boiler furnaces are provided where each burner includes a fuel nozzle surrounded by a secondary air outlet. The fuel nozzle and secondary air outlets may tilt in tandem with respect to an air plenum supplying inner secondary air and a fuel carrier providing fuel. Also provided are outer secondary air buckets that may independently tilt with respect to a frame connected to the air plenum. This arrangement can be installed as a retrofit in a conventional horizontal furnace system or in a newly built system. The fuel nozzle and secondary air outlet, and secondary air buckets may all tilt in unison or may all tilt independently. The tilting assists with optimizing a flame temperature profile within the furnace.

Abstract: Disclosed herein is a novel pivot pin assembly (410, 420 430, 600) for pivotally attaching nozzle tips (200) to stationary nozzles in a solid fuel furnace. The pivot pin assemblies allow rapid replacement of the nozzle tips (200). The pivot pin assembly (410, 420 430, 600) employs fasteners that or recessed or have an aerodynamically shaped head (610). The head (610) includes a leading edge (613) and optionally a trailing edge (615) that are aerodynamically shaped to reduce corrosion and erosion. The pivot pin assembly pivotally attaches the nozzle tip (200) to the stationary nozzle (110). It employs fasteners that are accessible from a furnace side through a central opening of the nozzle tip (200). This allows removal of the nozzle tip (200) from inside the furnace greatly simplifying nozzle tip (200) replacement.

Abstract: This invention provides a heating tube and a heating plate which are capable of greatly improving the heat transfer efficiency of a conventional finned heating pipe and a conventional heating plate. Copper oxide powder is deposited in a gas phase on an adhesive agent-applied synthetic resin foam, and a copper plate on which the same metal powder has been deposited is laid on one surface of the foam and pressure-fixed thereto lightly by a roll press to be laminated. The synthetic resin foam is then burnt out in a combustion furnace to obtain metal foam of copper oxide on the copper plate. When the resultant product is reduction sintered in a reducing atmosphere such as a hydrogen reducing furnace, a copper foam having a copper plate on one surface thereof can be obtained. This copper foam can be used as it is as a material for fabricating a heating plate for a heat exchanger.
