2016/12/15 · Dynamic performance simulation of a CFB boiler in a commercial-scale power plant is reported. The boiler system was modeled by a finite number of heat exchanger units, which are sub-grouped into the gas-solid circulation loop, the water-steam circulation loop, and the inter-connected heat exchangers blocks of the boiler. This dynamic model is an extension from the …

The basic structure of the model includes a system of 46 differential equations, which represent the mass and energy balance for all phases at any point of the equipment. The results generated by the simulation were compared with values measured during the operation of fluidized bed units by Babcock & Wilcox and by the National Coal Board.
