Abstract

For the combustion process of industrial circulating fluidized bed boiler (CFBB) with nonlinearity

time-variation

strong delay and multivariable coupling

considering how to satisfy the economic target with decreasing power consumption

an two level multivariable predictive control (MPC) method was proposed. The method based on the constrained control of main steam pressure

bed temperature and flue gas oxygen content is constructed to optimize the economic target. The industrial application result demonstrates that the proposed method can decrease the coal consumption of unit steam while assuring the steady of the main process parameters of the boiler combustion and bring high economical profit.
