    Abstract: A coal nozzle for a burner on a pulverized coal fired furnace which includes an elongated tubular nozzle having an inlet for receiving a flowing stream of coal/air mixture and an outlet for discharging the flowing stream into a combustion zone of a furnace for combustion, and an inlet elbow connected to the inlet of the tubular nozzle. The interior outer surfaces of the elbow include a staircase surface configuration for engaging the incoming flowing stream whereby coal ropes in the stream are broken up for thereby improving flow distribution of the stream.

    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.

    Abstract: Subject A solid fuel burner and its combustion method suited for encouraging fuel ignition and avoiding slugging caused by combustion ash, wherein a gas of low oxygen concentration (exhaust combustion gas) is used as a carrier gas of such a low grade solid fuel as brown coal. Means for Solving the Subject An additional air nozzle 12 for jetting additional air having a velocity component in the circumferential direction of a fuel nozzle 11 is provided in the fuel nozzle 11, thereby encouraging mixing between the fuel and air in the fuel nozzle 11. Further, the amount of air supplied from the additional air nozzle 12 is adjusted in response to the difference in combustion loads. Under light load, the amount of air supplied from the additional air nozzle 12 is increased so as to increase the oxygen concentration of the circulating flow 19 formed downstream of the outside of the outlet of the fuel nozzle 11, whereby stable combustion is ensured. Under heavy load, by contrast, the amount of air supplied from the additional air nozzle 12 is decreased, and a flame is formed away from the fuel nozzle 11 in such a way that burner structures and furnace wall will be less subjected to radiant heat.
