Patent ID: 8146540

Claim:
A continuous steam generator, comprising: a surrounding wall forming a gas draught where: a lower area is formed from evaporator tubes welded to each other to form a gas-tight seal, and an upper area is formed from superheater tubes welded to each other to form a gas-tight seal; and a water separator system having a plurality of water separator elements where each element is connected downstream of fewer than ten evaporator tubes and upstream of fewer than ten superheater tubes on the input side of a water separator, from an evaporator, wherein a plurality of burners are arranged in the area of the evaporator tubes in the surrounding wall and the water separator elements are positioned at a height of not more than 20 m above the topmost burner; and wherein an adjustment valve controlled by an assigned closed-loop control device is arranged in an outflow tube connected to at least one water collection container receiving fluid from the water separator system, the closed loop control device receiving a characteristic input value from a sensor for the enthalpy of the flow medium on the steam-side outlet of the superheater surface.
