Title:
METHOD OF CONTROLLING PRESSURIZED FLUIDIZED BED TYPE COMBUSTION DEVICE
Document Type and Number:
Japanese Patent JP04260708
Kind Code:
A
Abstract:
PURPOSE: To provide a method for controlling a height of fluidized bed capable of performing an accurate adjustment of removal of particles from a fluidized bed type combustion furnace in response to a varying speed of load.
CONSTITUTION: A differential pressure meter 35 is installed at a part of an air stream transporting pipe 23 for use in transporting particles from within a combustion furnace 1 to a medium container 11. Its differential pressure signal is calculated and processed so as to control aeration gas 27 at an L valve 22.
