Abstract. This paper presents a dynamic model of a supercritical circulating fluidized bed (CFB) Benson type once-through utility (OTU) boiler. The water-steam cycle of the boiler is modelled using generalized model blocks able to handle thermodynamics of water, saturated water-steam mixture, and superheated steam under sub- and supercritical pressures.

The once through boiler has high load response characteristics due to the fact that it does not have a drum and has a much lower water inventory. In the once through boiler, many times the load change response is dictated by the firing system and its controls rather than the boiler, per-say.
