Abstract: A fuel head assembly (120) for a pulverized coal nozzle includes removeable back cover (123) that may be removed substantially horizontally to allow access to liners (141,143,145) inside of the fuel head assembly (120) for servicing. This may be used in places where there access from above the fuel head assembly (120) is restricted. The liners (141,143,145) are constructed of a wear-resistant material and include curved vanes (131,133) for more evenly distributing pulverized solid fuel particles, and for reducing erosion of the fuel head assembly (120).
