    Abstract: Disclosed herein is an apparatus and method of constructing a stationary wear-resistant stationary nozzle 200 and/or nozzle liner 230 for solid fueled furnaces. A transition section 210 is constructed from several flat pieces 211-218 several that may have identical starting shapes. This reduces manufacturing complexity and costs. All pieces 211-218 have a high-wear weld overlay on their inner surface 316, 416. Corner pieces 215-218 are folded into a corner shape at an outlet edge 412 and rolled into a curved shape at an inlet edge 411. Horizontal 211, 212 and vertical pieces 213, 214 are only rolled at an inlet edge 311. The pieces have seam tab 240 along longitudinal edges that are welded together to construct a transition section 210. The transition section 210 may be used as a liner to reduce wear in an existing stationary nozzle or may be constructed to be connected to an inlet piece 220 to form a strong, wear-resistant coal nozzle 200.
