Abstract

A nonlinear dynamic model of a multicell, atmospheric-pressure, fluidized-bed combustion steam generator is developed in state-space form. All model parameters are physical quantities derived from design data, and the model can be readily adapted to other fluidized-bed combustion steam generators. Steady-state performance of the nonlinear model is predicted at 100, 87. 5, and 75% load levels, and local stability is examined in this range. Frequency response characteristics of several system variables and transient response of the system following a coal feed rate disturbance are presented to illustrate use of the model.
