Test Your Knowledge: Boiler Chemical Cleaning

Most engineers and operators know (or should know) that boiler tubes containing deposits create long-term reliability problems for the boiler. Long-term overheating of the metal will result from prolonged operation with heavy tube deposits. The tubes will first bulge and then fail. Because the deposits tend to be widespread, this generally means that large sections of […]
