Evaporator system

An evaporator system for an industrial boiler, comprising:

• a heat transfer system for generating a water-steam mixture,
• a separator for separating water and steam from the water-steam mixture, and
• a dryer for drying separated wet steam,
• wherein the separator comprises at least one horizontal vessel containing a required minimum amount of water, a relatively small steam volume and internals for the separation of water and wet-steam,
• wherein the dryer comprises at least one vertical vessel containing internals for drying the wet steam to predetermined values by separating liquid from the wet-steam,
• wherein the at least one horizontal vessel and the at least one vertical vessel are connected to each other by at least one wet-steam piping through which separated wet-steam is transported from the at least one horizontal vessel to the at least one vertical vessel,
• wherein the at least one horizontal vessel comprises a connection to outlet conduits of an at least one evaporator heat transfer section of the heat transfer system for transporting a water-steam mixture from the at least one evaporator heat transfer section to the at least one horizontal vessel,
• wherein the at least one horizontal vessel further comprises a connection to at least one downcomer conduit for transporting water from the at least one horizontal vessel back to inlet conduits of the at least one evaporator heat transfer section,
• wherein the at least one vertical vessel comprises a connection to at least one dry-steam piping for discharging dried steam out the vertical vessel, and
• wherein the at least one vertical vessel comprises a connection to a liquid drain piping for transporting liquid from the at least one vertical vessel back to the inlet conduits of the at least one evaporator heat transfer section.
