A solid particulate fuel/air burner has opposing fluted members (20) within a rectangular conduit (16) which in operation forms a nozzle. Splitter plates (30) with the fluted members (20) define passages through which a particulate solid fuel and air flow to a combustion chamber. The passages so defined provide and control separate streams of the mix such that flame retention at the exit of the conduit (16) is achieved and reduced NOx is produced and the gathering of ash in the conduit (16) avoided by the obviation of recirculation of the products of combustion into the conduit. <IMAGE> |
