Stable A few questions. 1) did you change water treatment companies, products or anylitical set points? 2) What is the operating pressure? 3)What is the steam used for? 4) Does the system experience water hammer or hard banging pipes? 5) Has the prblem been a issue for several years?.. I wouldnt call it shrink & swell, that sounds like a happy lable some one gave the issue. The problem is typically referred to as surging water. It can be caused by several things from poor water treatment design to oil or old filming amines in the system, even twinky filling after a year or two use will cause it; mechanical design or system installation, steam flow controls, steam piping system and even the main steam header, all of the above can be the cause. This is a issue that should be corrected, it can result in damages in several different ways to the boiler as well as steam driven equipment and heat exchangers, it may also be costing big money in efficiency loss. I wish you could be given a short sweet answer but,, nope. The problem can be easily diagnosed if the right person looks at it. But this forum will give it a shot!
