Embodiment Construction

[0041] Use of the terms "a" and "an" and "the" and similar references in the context of describing the present invention (particularly in the context of the appended claims) is to be read to cover both the singular and the plural unless hereinafter otherwise indicated, or clearly contradicted by the context. The modifier "about" used in conjunction with a quantity is inclusive of the stated number and has the meaning dictated by the context (eg, it includes the degree of error associated with measuring the particular quantity). All ranges disclosed herein are inclusive of endpoints, and the endpoints can be combined independently of each other.

[0042] If the pivot pin is not welded, replacing the nozzle tip 200 from the furnace side would be the most straightforward way.

[0043] The interior of the furnace is covered with water pipes for collecting heat and for generating steam. These burners can be several feet from the bottom of the furnace. Therefore, temporary scaffo...

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.

Description

[0001] Cross References to Related Applications [0002] This application is a reference to U.S. Application Serial No. 12 / 618,031, entitled "PIVOT PIN FOR FURNACE SIDE REMOVAL," filed November 13, 2009, by Briggs et al. Continuation in part, and priority of that application is claimed. technical field [0003] The present disclosure relates to burners for solid fuel fired furnaces, and more particularly, to burner nozzle tip designs that allow for easier removal and maintenance. Background technique [0004] Solid fuel stoves have common uses, such as for firing boilers, to generate steam and electricity. The solid fuel is typically pulverized coal. The coal particles of the pulverized coal are carried in the flowing air stream and are blown into the combustion chamber of the furnace where they burn. [0005] figure 1 is a schematic illustration of the fuel combustion compartment 100 of a typical solid fuel fired furnace. figure 2 is showing figure 1 Side elevation v...
