How to Destroy a Boiler -- Part 1

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.

Steam and Condensate - A basic overview of a steam system - The Boiler House

The hot gases from the burner pass backwards and forwards up to 3 times through a series of tubes to gain the maximum transfer of heat through the tube surfaces to the surrounding boiler water. Once the water reaches saturation temperature (the temperature at which it will boil at that pressure) bubbles of steam are produced, which rise to the water surface and burst.

A typical warm-up arrangement may be that the control valve is closed until the boiler is required. At this point a pulse timer slowly opens the control valve over a predetermined time period. This arrangement also has the advantage that it does not require manpower (unless the boiler is heated up from cold) over the boiler warm-up period, which may be during twilight hours.
