Boiler Introduction

Steam generators are like boilers in that they are fired by gas and produce steam, but they are unlike boilers in that they do not have large pressure vessels and are made of light-weight materials. The fact that they do not have pressure vessels means that in most locations they do NOT require a boiler operator (always confirm with local codes).

The importance of pH in steam-boiler water

It comes into play with steam boilers because a pH between 7 and 9 (slightly alkaline) is just right. If the pH is lower than that, the water will start eating the pipes. If it’s higher than that, the water won’t corrode metal, but it may begin to foam, and that’s not good.
