A method for starting a vertical forced-flow steam generator in a waste-heat steam generator, wherein feed water is fed to the forced-flow steam generator as working fluid, and there flows firstly through a feed-water preheater and then through an evaporator and is at least partly evaporated, wherein the partly evaporated working fluid is fed to a water separation system, in which non-evaporated working fluid is separated from evaporated working fluid and is collected, in which at least part of the non-evaporated working fluid is fed geodetically to the evaporator and, beginning from a certain quantity of accumulating non-evaporated working fluid, a remaining part is automatically removed from the water separation system. A corresponding device is for starting a vertical forced-flow steam generator according to the method.

A separator circuit for a steam generation system. The separator circuit comprises a steamer connection tube and a liquid bin tube that extends vertically between a steam outlet for providing steam to a cavity of a cooking appliance and a recirculation tube for routing condensation back into the provided steam generation system. A slide tube is sloped downwardly from the steamer connection tube to the liquid bin tube for gravitationally accelerating condensation from the steamer connection tube through the liquid bin tube and into the recirculation tube. A vortex section is located between the slide tube and the liquid bin tube and includes a choke wall. The choke wall extends from a first end decreasing a cross-sectional flow path of the vortex section to a second end in a direction of the liquid bin tube.

A filtration device is provided, including: a casing, including an inlet passage and an outlet passage which are arranged on an extension direction; a plurality of blades, extending spirally on an inner circumferential wall of the inlet passage relative to the extension direction; a guiding mechanism, including a first tapering portion tapered in a direction toward the inlet passage, disposed in the casing and located between the plurality of blades and the outlet passage.

An evaporator system for an industrial boiler, containing a heat transfer system, a separator for separating water and steam and a dryer for drying the separated wet steam. A horizontal vessel contains a required minimum amount of water, a relatively small steam volume and internals for the separation of water and wet-steam. A vertical vessel contains internals for drying the wet steam to predetermined values by separating liquid from the wet-steam. The horizontal vessel and the vertical vessel are connected to each other by wet-steam piping through which separated wet-steam is transported from the horizontal vessel to the vertical vessel. The vertical vessel has a connection to dry-steam piping for discharging dried steam. The vertical vessel has a connection to a liquid drain piping for transporting liquid from the vertical vessel back to the inlet conduits of the evaporator heat transfer section.
