    • A steam generator, in particular a waste-heat steam generator, includes first and second evaporator heating surfaces located in an elongate gas flue for hot gas. A first supply line for feed water is throughflow-connected on an inlet side to the first evaporator heating surface, while the second evaporator heating surface is throughflow-connected on an inlet and an outlet side to a low-pressure drum. The low-pressure drum is provided with a second supply line for feed water. The first supply line has a first treatment point and the second supply line a second treatment point. Each of the treatment points serves for adding and/or extracting chemicals for water treatment, so that each evaporator heating surface can receive only feed water which is conditioned according to regulations applying to that evaporator heating surface. A method for operating the steam generator is also provided.
    • 蒸汽发生器,特别是废热蒸汽发生器,包括位于用于热气体的细长气体烟道中的第一和第二蒸发器加热表面。 供水的第一供应管线在入口侧通过流动连接到第一蒸发器加热表面,而第二蒸发器加热表面在入口和出口侧通过流动连接到低压桶。 低压桶设置有用于给水的第二供应管线。 第一供应管线具有第一处理点,第二供应管线具有第二处理点。 每个处理点用于添加和/或提取用于水处理的化学品,使得每个蒸发器加热表面只能接收根据适用于该蒸发器加热表面的规则进行调理的给水。 还提供了一种用于操作蒸汽发生器的方法。
