Cyclic Operation of Feedwater Heaters

January 10th, 2017 - Milwaukee Wisconsin

The photo below shows a high pressure feedwater heater which has been condemned. Cyclic operation will destroy improperly designed Feedwater Heaters. Contact AM-EX for our state of the art designs to ensure FEEDWATER HEATER integrity during cyclic operation. 

AM-EX utilizes specialized desuperheating zones, drainscooling zones, and special channel designed specifically for cyclic operation. 

Feedwater Heater Failure During Cyclic Operation - Choose AM-EX to Design Feedwater Heaters For Your Cyclic Needs
The specific photo above is a breech-lock design. These types of designs, are older designs which have a tendency to crack, and are not recommended specifically in cyclic operations. The crack propagation is of particular concern for load following plants which experience rapid power plant cycling. In addition, the breech-lock design is difficult to service due to special equipment requirements. 

The above and below photos are of a high pressure feedwater heater in cyclic operation which was condemned (and replaced with an AM-EX High Pressure Feedwater Heater designed for cyclic operation) due to the extensive indications and channel failure. Of particular note is the crack propagation of an undersized knuckle radius and inadequate breech lock lug design.
