摘要

HEARTH AND PROCESS FOR FLUIDISED-BED TREATMENT OF A FUEL Hearth and process for the fluidised bed treatment of a fuel consisting of solid particles. The grid for conveying gaseous fluidisation and/or forcing fluid to a treatment chamber comprises two separately supplied gas distribution means of channels, respectively a first gas distribution means of channels with orifices widened towards the top, for the fluidisation of a particulate material, and a second gas distribution means of tubular channels, opening out above widened orifices, for forcing the particulate material.
