Abstract: A solid fuel nozzle tip for issuing a flow of mixed solid fuel and air into a boiler or furnace includes an outer nozzle body having an outer flow channel extending therethrough from an inlet to an outlet of the outer nozzle body. An inner nozzle body has an inner flow channel extending therethrough from an inlet to an outlet of the inner nozzle body. The inner nozzle body is mounted within the outer nozzle body with the inner flow channel inboard of and substantially aligned with the outer flow channel. The inner and outer nozzle bodies are joined together so as to accommodate movement relative to one another due to thermal expansion and contraction of the outer and inner nozzle bodies.

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.
