Method and system for lining a coal burner nozzle

摘要

A method and liner system for a pneumatically conveyed particulate conduit are provided. The conduit includes an inlet opening, an outlet opening, and a duct extending therebetween. The system includes a first polygonally-shaped wall member extending from an inlet opening end of the conduit to an opposing outlet opening end of the conduit. The first wall member includes a substantially planar body. The liner system further includes a second polygonally-shaped wall member extending from the inlet opening end of the conduit to the opposing outlet opening end of the conduit. The second wall member includes a substantially planar body having an integrally formed anti-roping bar that extends outwardly from a surface of the second wall member a predetermined height into a flow path through the duct. The liner system further includes a curved polygonally-shaped corner member extending from the inlet opening end of the conduit to the opposing outlet opening end of the conduit.
