A fluidized-bed system is claimed for feeding coal or a coal-limestone mixture into a fluidized bed combustor. The system includes: a perforated horizontal distributor plate dividing the chamber into upper and lower chamber sections; means for feeding solid fuel particles into the upper chamber section; a source of high velocity gas connected to the lower chamber section and passing through the plate into the upper chamber section for entraining the particles; means for heating the high velocity gas before it is introduced into the upper chamber; an entrainment section defined by converging upper sides of said fuel feeding chamber; and a stream splitting section disposed above said entrainment section and connected to a plurality of pneumatic transport lines each penetrating the distributor plate of a fluidized bed combustor and terminating in an outlet feedport.
