First: to act as an automatic non-return valve by preventing a backflow of steam from the main steam header to the boiler.
首先，能过作为一个自动逆止阀，防止蒸汽从主蒸汽加热器上倒流到锅炉里。
When more than one boiler is connected to the main steam header, a stop check valve should be installed in the pipeline between each boiler and the header.
如果连接主蒸汽热水器的锅炉不止一个，则在每个锅炉与热水器之间的管路上都应该安装一个截止止回阀。
Siting of a sludge treatment system at a power plant, where high-pressure steam generated by the SCWO process could be fed into a steam header, would provide greater economic benefit.
若选择把污泥处理系统坐落在发电厂内，超临界水氧化装置所生产的高压蒸汽可融入发电厂内现有的高压蒸汽总管，这样可以为发电厂带来经济效益。
Achieve continuous balance between produced and consumed steam. This master pressure control approach controls total heat input into boilers, as well as total steam flow into each header.
实现产出和消耗蒸汽的连续平衡。主压力控制方法控制着输入锅炉的总热量以及流入每个锅炉联管箱的蒸汽量。
Since the header on the evaporating heating surface adopts pre-separation structure, the effectiveness and speed of water-steam separation 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。
In the boiler's inspection, some fillet weld's crackles were found on the same side of the header of steam collecting channel for some boilers that had the same style.
在锅炉检验中，发现几台同类型锅炉的集汽联箱的管座角焊缝，均在相同一侧出现裂纹。
