Steam Turbines

Mr. Lieberman – I read in your book, “A Working Guide to Process Equipment,” that the steam chest pressure of turbines should not be less than 10 or 20 psi of the supply pressure. But how to measure the steam chest pressure when a turbine is in operation?
--Prabu, India

            Prabu – If there is no connection on top of the steam chest, then you may use the small (½”) condensate drain to the sewer from the bottom of the steam chest. I just place my gauge on this drain. Closing a port valve will cause this pressure to increase which will save steam. Run at the maximum steam chest pressure by closing port valves or until governor is 100% open. Good to hear from you again.
