Solid fuel nozzle tips
First Claim
1. A solid fuel nozzle tip for issuing a flow of mixed solid fuel and air to a boiler comprising:
- a tip body having an inlet and an outlet defining a longitudinal axis therebetween, wherein the tip body includes a slot on an inlet side of the tip body extending in a direction parallel to the longitudinal axis, wherein the slot includes an opening facing the inlet side of the tip body and wherein the slot includes a recess formed at an angle with respect to the longitudinal axis to at least partially retain a pivot pin, wherein the tip body includes an inner shell and an outer shell, wherein the outer shell is radially outward from the inner shell with respect to the longitudinal axis, wherein the slot is defined on the inner shell, wherein the outer shell includes a tab radially outward from the slot with respect to the longitudinal axis, and wherein the tab extends from an end of the outer shell over a portion of the inner shell to form a retaining aperture therebetween.
