2014-6-16 · A boiler-drum is divided into two parts; the upper part contains saturated steam while the lower part contains a steam/water mixture. The ratio of the stea m in that mixture is defined in this work as the steam volumetric ratio. On the other han d, balance equations are applied to the drum. The resulting equations are used to model the drum-level.
