Abstract
PURPOSE: To improve combustion of solid fuel in a fluidized-bed heating apparatus in use of the solid fuel such as coal, by disposing hearths at least in two stages with level difference, and providing an individual wind box for each of the hearths.
CONSTITUTION: A lower hearth 12 is disposed centrally at the bottom of a heating furnace 1 and an upper hearth 13 is disposed above the lower hearth 12 in the manner of surrounding the same. Downwardly of these hearths 12, 13, there are provided respective wind boxes 14, 15. Further, the hearths 12, 13 are provided with respective diffusers 16, 17. A solid-fuel feeding pipe 5 is connected to the furnace 1 at a part thereof located upwardly of upper hearth 13, and pipes 7, 8 for feeding substances such as lime to be treated into fluidized bed 6 and discharging the same to the outside after treatment, respectively, are also connected to the furnace 1. In operation of the apparatus, combustion is promoted by controlling the flow rate, velocity and other factors of air supplied to wind boxes 14, 15 via respective air pipes 18, 19 and ejected into the fluidized bed from respective diffusers 16, 17 appropriately and thereby making solid substances having large grain sizes drop onto the lower hearth 12.
