Patent ID: 8381667

Claim:
An adjustable fuel nozzle system for providing fuel to a combustion chamber of recovery boiler comprising: a) an upper fuel nozzle assembly, comprising: i. an inlet line for receiving said fuel, ii. an extension for directing said fuel from the inlet line through the extension having a first and second end, the first end being fluidically connected to the inlet line, iii. a nozzle outlet fluidically connected to the second end of the extension allowing said fuel to exit the extension as a jet of fuel; b) a lower fuel nozzle assembly, comprising: i. an inlet line for receiving said fuel, ii. an extension for directing said fuel from the inlet line through the extension having a first and second end, the first end being fluidically connected to the inlet line, iii. a nozzle outlet fluidically connected to the second end of the extension allowing said fuel to exit the extension as a jet of fuel; and c) an adjustment section adapted to hold both the upper and lower fuel nozzle assemblies in a desired orientation relative to each other, and to permit adjustment of the orientation of both the upper and lower fuel nozzle assemblies keeping the same desired relative orientation between the nozzle assemblies; wherein the adjustment section comprises: a fixed anchor pipe having a center point; an anchor clamp for pivotally attaching a lower clamp to the fixed anchor pipe allowing both fuel nozzle assemblies to pivot simultaneously about the center point; and a group rotation hinge attached between the lower clamp and a anchor plate; where the group rotation hinge permits rotation about an axis that is perpendicular to an axis about which rotation about the anchor clamp permits.
