Back-pressure turbine outlet steam flow meter
Thread Content
For a back-pressure steam turbine with an inlet pressure of 3.5 Mpa and a flow meter at the outlet, is it necessary to install another steam flow meter at 1.0 Mpa? Have you installed such a meter?
We don’t have it here either; we only know the medium-pressure flow rate, so there’s probably no need to adjust it. Can this be calculated?
We are currently calculating the low-pressure steam flow based on the medium-pressure steam that enters. Is this the correct way to do it?
It’s not installed; when doing calculations, the air leakage from the turbine must be taken into account. Our turbine has quite significant leakage
We don’t have that either; we calculate the exhaust volume based on the intake volume
Where is the leak coming from? Is it the steam seal cooler?
We don’t have one installed here, but I’ve heard from others that there is a flow meter at the outlet of the turbine in their factory
Most plants do not have this installed; the steam output is basically calculated based on the steam inlet volume.
