Title: Fluidized-bed combustion device
Inventor: OOTANI YOSHINORI
IPC: F23C10/18
Filed: 1983-05-14
Abstract: PURPOSE:To prevent heating tubes from being eroded and contrive to enhance the combustion efficiency by a structure wherein a veriable type duct collector is realized by arranging turning blades in a cyclone dust collector. CONSTITUTION:When combustion gas containing ashes to be caught therein is supplied from a gas inlet pipe 21, the combustion gas together with the ashes is given swirling force by means of turning blades 17, resulting in separating the ashes to be caught from the combustion gas so as to lead through a conical part 22 to a recovery port 24 of the ashes to be caught. On the other hand, the resultant comparatively clean combustion gas is led through a central gas outlet pipe 23 to a dust collecting process. In such a structure as mentioned above, the dust collecting efficiency is made variable by changing the inclination of the turning blades 17 through the stationarily turning of driving shafts 20, which is caused by shifting a coupling belt 18 with the turning of a motor 19. The change of the inclination angle of the turning blades 17 in response to kinds of coals enables to prevent heating tubes from being eroded and to select recycle rate at will, resulting in enhancing the combustion efficiency.
