Overview

This course, based on the document "Guide to Orifice Plate Steam Traps" published by Oak Ridge National Laboratory, provides guidance on when orifice plate steam traps should be considered for use in new or existing steam systems.  As the name implies, orifice plate steam traps are simple devices containing a thin plate with a small-diameter hole in the center.  The orifice restricts the amount of condensate or steam that can flow out of the system.  An optimally sized hole will allow only condensate to flow out, while allowing little or no steam to escape. 

Orifice plate steam traps have an advantage over conventional steam traps in that there are no moving parts that can break.  However, there are few applications that are suitable for orifice plate steam traps.  The pressure and the condensate load must be relatively constant in order for an orifice plate steam trap to provide reliable and efficient service.  And the steam must be relatively clean. Debris can cause the orifice to clog and abrasive particles can cause the orifice to grow in size due to erosion.

In addition to discussing orifice plate steam traps, this course covers the basics of other types of conventional steam traps, such as thermostatic, mechanical and thermodynamic traps, including their relative merits in different applications.

The student must take a multiple-choice quiz consisting of fifteen questions at the end of this course to obtain PDH credits.
