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。
