Is a filter installed at the inlet end of the turbine steam?

This post was last edited by whthday on 2015-6-4 19:08. I would like to ask the experts: Is it necessary to install a filter screen at the steam inlet end of a turbine pump? The production unit says the steam contains impurities, but I think if the filter screen gets damaged, the consequences could be even worse. May I ask the experts: is it allowed by the standards to use such a filter? Why?
Our turbine inlets are all equipped with inlet filters~~
The quick shut-off valve itself comes with a filter
This can be added; just choose a good manufacturer whose products offer reliable quality. Filters are generally available in such units, and quick-close valves are already included.
A filter should be installed; the appropriate type of filter can be chosen based on the conditions of the steam. It can be integrated into the vapor-liquid separation tank at the steam inlet.
What was said on the 4th floor is correct. Generally, there is a filter screen inside the main steam valve at the turbine inlet; you can take a look when you have the opportunity to disassemble it
If a quick-shut valve is included, it will definitely meet the requirements and there will be no issues in the future； If it is added, where should it be installed, how to choose the appropriate model, and how to maintain it? In particular, choosing the right model is very important; I think it’s better not to add it at all ； If steam contains impurities, the issue should be addressed by improving the quality of the steam; using filters, in my opinion, is not a viable solution.
The manufacturer’s opinion is correct. The original poster needn’t worry about these issues; the reason is simple: your work experience is far less extensive than that of the manufacturers, whose experience is built on past setbacks. A renowned turbine manufacturer abroad even requires the installation of \"steam washing towers\" – devices used to wash the steam in order to remove any liquid droplets and particles carried in it, thus preventing corrosion of the impellers (as turbine speeds are quite high). . So it’s quite normal to add a filter screen; I don’t recommend making any changes to this. . Furthermore, for such issues, one should not try to find any basis in regulations; regulations are also established by humans, and they primarily serve to set principles that guide and standardize actual engineering projects. It is impossible for them to specify whether certain details in projects and equipment are permitted or prohibited. . Many people on the forum want to ask specific questions about whether certain rules exist; they always turn to those rules for answers, but it’s most important to use one’s own judgment.
That’s a great question. I have the same doubts, but our workplace also uses filters, which are those cone-shaped nets.
The fundamental approach is to control the quality of the steam; regarding filters, please consult the manufacturer
