摘要
An ignition and combustion supporting burner for pulverized solid fossil fuel comprises an axial conduit for feeding the pulverized fuel in a primary combustion supporting gas. The shape of a refractory tap-hole enables the initial part of the flame to be confined. A conduit for feeding tertiary combustion supporting gas is concentric with the tap-hole and partially or totally surrounds it. The burner also incorporates a flame detector device and an igniter in the refractory tap-hole or in the axial conduit. The axial conduit is provided with translation means providing for adjustment of the length of a chamber for preliminary mixing of the fuel and part of the combustion supporting gas comprised between the end of this conduit and the inlet of the tap-hole.
