Effect of Bed Pressure Drop on Performance of a CFB Boiler ...

The effect of bed pressure drop and bed inventory on the performances of a circulating fluidized bed (CFB) boiler was studied. By using the state specification design theory the fluidization state of the gassolids flow in the furnace of conventional CFB boilers was reconstructed to operate at a much lower bed pressure drop by reducing bed inventory and control bed quality. Through ...

Datadriven control for combustion process of circulating ...

Sep 23 2019 · However compared with the pulverised coal boiler the combustion process of CFB boiler is more complicated because of the larger time delay significant uncertainty and more coupled variables. In this study a datadriven proportionalintegralderivative (DDPID) control strategy is presented for the combustion control of CFB boiler to ...
