Fluidized-bed equipment and pressurized fluidized-bed (combustion) combined cycle apparatus

摘要

A bed height of a fluidized bed is detected which influences reaction of a fluidized-bed equipment. In the fluidized-bed equipment in which a fluidized particle is put into the vessel, physical properties at a plurality of points within the vessel are measured in a height direction thereof. An interior of the vessel is divided into upper and lower two regions. Physical property distribution curves of the respective regions are found, to find an intersection between the two curves as a bed height. Thus, it is possible to find the bed height of the fluidized bed which influences the reaction of the fluidized-bed equipment. An operating quantity which influences the reaction can be adjusted or regulated accurately.
