TG408 - Turbine Water Induction Awareness

2 days - 1.3 Continuing Education Units Awarded

Learn to avoid the possibility of experiencing a water induction incident. This Seminar reviews the latest ASME recommendations in detail; to include power plant design, instrumentation for detection, and operator action. Class presentation includes some relevant case studies that demonstrate just how quickly we can get ourselves in trouble if operating recommendations are not followed.

This Seminar is recommended for engineers, shift supervisors, operation superintendents, watch engineers.

Seminar OBJECTIVES

1. Describe recommended design practices that have been intiated to protect turbine equipment from water induction.
2. To list instrumentation typically available for detection of a water induction event.
3. Given an alarm situation, describe what corrective action should be taken and why.
4. Describe what type(s) of damage might occur as a result of water induction.
