Straight Length Before and After Strainer at Steam Turbine Inlet
Straight Length Before and After Strainer at Steam Turbine Inlet
(OP)
Hi,
A manufacturer of steam turbine requires a long straight length at upstream and downstream of a strainer at steam turbine inlet.
The turbine is about 14MW and steam flow is about 85t/hr. Size of inlet pipe is 8in. The length of strainer is 650mm. The manufacturer requires 2500mm straight length at upstream and downstream of the strainer. Is this requirement necessary for such cases? Or does it have a technical reason?
Could you please share with me your experience.
Thanks in advance.

RE: Straight Length Before and After Strainer at Steam Turbine Inlet
Straighten sections are normally associated with a flow measurement device like orifice or nozzle. And then measurement of steam flow in the pipe were rare.

So in short, yes the design of the inlet pipe described by the OEM should be followed.

I learned something new today, THANKS
would this be the type of cyclone seperator of which you mentioned.

I can see they would be benificial in the industrial boiler / turbine application.
(and the need for straigntening sections prior and aft)

The strainer is a common cone type one and not special, not cyclone type.
Thank you all.
