DESIGN METHOD OF FLUIDIZED-BED REACTOR, AND FLUIDIZED-BED REACTOR DESIGNED THEREBY

摘要

PROBLEM TO BE SOLVED: To provide a design method of a fluidized-bed reactor, in which precise temperature control of the temperature instability type fluidized-bed reactor is realized. ! SOLUTION: The design method of the fluidized-bed reactor is used for the temperature instability type fluidized-bed reactor having: a plurality of temperature detection parts; plural series of heat removal tubes for cooling; and such a temperature control system that the amount of a cooling medium to be made to pass through the heat removal tubes is adjusted by moving a control valve stepwise. The design method of the fluidized-bed reactor comprises the steps of: expressing a heat removal function of the heat removal tube as a function of (a dead time)+(a first-order lag time) of a cooling effect of the heat removal tube; and determining the number of the plural series of the heat removal tubes and a disposal pattern of the heat removal tubes by utilizing a fact that parameters in the expressed function depend on a dista
