Abstract
A fluidized-bed furnace recirculates solids by way of one or more cyclone precipitators (6), the solids outlet of which communicates with the fluidized bed (4) by way of a trap (8) and a directly downstream chute (10). The coal intake opens into the chute. The outlet (9) from the trap (8) communicates with the chute (10) through a transitional section (11). The transitional section tapers out from the outlet from the trap and then in to the chute. The coal intake is above the wider section of the transitional section.
