Since the header on the evaporating heating surface adopts pre-separation structure, the effectiveness and speed of water-steamseparation in the drum are improved.
同时，锅炉的蒸发受热面上集箱采用预分离结构，提高了汽包的分离效果和分离速度。

Separation of water and gas is reliable (water vapor enters from bottom of valve by the U general type), remain the state of water sealing in the valve, effectively prevent leakage of steam.
汽水分离可靠（水汽经U型普通从阀底部进入），阀内始终处于水封状态，有效阻止蒸汽泄漏。

The design of steam generator should not only have highly efficient and compact separator and dryer, but also an adequate height of gravity separation space.
