<p>An evaporator system for an industrial boiler contains a heat transfer system for generating a water-steam mixture, means for separating water and steam from the water-steam mixture and means for drying the separated wet steam. The separating means comprises at least one horizontal vessel (1) containing a required minimum amount of water, a relatively small steam volume and internals for the primary separation of water and steam and at least one vertical vessel (2) containing internals for drying the wet steam to pre-determined values and containing a water level (WL) in a certain range high enough to create the necessary pressure to force the separated water to flow back from the vertical vessel (2) to the evaporator system. The horizontal vessel (1) and the vertical vessel (2) are connected to each other by a piping (6) through which the separated wet steam is transported from vessel (1) to vessel (2). The horizontal vessel (1) das a connection to a piping (4) for transporting water to the horizontal vessel (1), and the vertical vessel (2) has a connection to piping (8) for extracting dried steam from the vertical vessel (2).</p> |
