Abstract

A continuously operated boiler heated with a pressurized circulating fluidized bed firing consists of a fluidized bed burner chamber and one or more cyclone separators connected in series after the fluidized bed burner chamber and on the flue gas side. A fluidized bed cooler is connected in series after each cyclone separator which cooler is connected by way of a dip pot with the solids output of the cyclone separator on one hand and with the fluidized bed burner chamber on the other hand. A return conduit is connected with the dip pot which opens into the fluidized bed burner chamber. Pressure vessels house the fluidized bed burner chamber, the cyclone separator and the fluidized bed cooler. The fluidized bed cooler, the cyclone separator and the dip pot are thereby combined into a unit which is housed in the common pressure vessel.
