I am working with 1" medium pressure steam mains (45 psig) for a batch process. Time between batches is usually short (to the order of minutes) but depending on the day the delay can be hours, and even longer over weekends or holidays.
We recently installed a full set of orifice (venturi) type steam traps. When we start up, the orifices can't handle the condensate load and the back up condensate is causing water hammer in some sections of the piping.
We are a little tight on budget but will look to installing additional (non-orifice) traps in the problem portions of the piping. In the meantime, we are resorting to manually opening/closing the bypass valves to vent the initial condensate.
Is there a better way to prevent condensate backup at startup on a batch process when using orifice/venturi steam traps?
