HRSG Freeze Protection Planning and Inspection

Tetra Engineering Group has extensive experience with HRSGs operating in potentially freezing environments. We’ve worked with plant owners from the North Slope of Alaska and Canada to Texas and Mexico where freeze damage and protection are important.

Our project experience in freezing includes:

 - Freeze damage to pressure parts during construction, commissioning and operation.
 - Proper design and operation of keep warm systems and practices.
 - Issues with restart/startup actions from frozen key instrumentation including flow meters,  drum level sensors and pressure sensors.
 - Issues with support systems such as make up water, tank storage due to freezing.
