  • the particles in the seal box 4 are introduced to the external heat exchanger 6 and are in-bed tube 5 under fluidizing condition.
  • bed materials 11 which comprise ash, sand and limestone etc. are under suspension by the fluidizing condition.
  • the circulating particles contain unburned fuel which contains a chlorine and combusts in the seal box 4 together with the fluidizing air B.
  • the unburned fuel thus combusted in the seal box 4 generates melted salts which contain sulfate and condense so as to adhere to a high temperature area in the heat exchanger 6 .

Because the unburned particles are thus combusted by the separation loop, and an amount of the unburned particles flowing into the external heat exchanger in which the in-bed tube is arranged is minimized and the service life of the in-bed tube is extended.
  • a separation loop comprises a path, such as a duct or a pipe, through which the corrosive components which are generated by the combustion in the separation loop are exhausted out of the seal box.
  • the path is connected with the furnace.
