The improper warm-up of a steam boiler is one of the most severe hardships a boiler must endure. Going through the cycle of start-up, operation, and shutdown for any boiler creates higher equipment stresses and, consequently, much more maintenance-type issues than continuous operation at maximum rated capacity.
The control of downtime corrosion has become increasingly important in recent years to prevent or inhibit pitting failures. Often, cold water that has not been deaerated is used for rapid cooling or start-up of a boiler. This is a risky operating practice, usually chosen for economical reasons.
For seasonal boilers even the best boiler water treatment program must be supplemented to prevent corrosion during the boiler’s non-operating months. Why do I need to lay-up my boiler anyway? Having the best boiler water treatment program on the planet may keep dissolved oxygen out of your boiler during normal operation, but it will not do
