Towards an Accurate Control of Circulating Fluidized Bed Combustor

Abstract:

Circulating fluidized bed combustion is a widely used technology because of its ability to burn a wide variety of fuels efficiently and in an environmentally acceptable manner. To guarantee optimal combustion performances, combustion stability is essential. This paper proposes a comparative approach to define a suitable control strategy for an accurate control of fuel combustion. Several control laws are therefore defined and applied on a dynamic nonlinear model, based on a pilot plant and representative of the main combustion phenomena: a conventional PID, a linear optimal control, a robust H∞ approach and a nonlinear control.
