Refractory damage is the most prevalent damage associated with a quick warm-up of a boiler from a cold start. Refractory by design transfers heat very slowly and therefore heats up much more slowly than metal. Also, as the air inside the furnace and refractory cool, moisture is absorbed from the air in the refractory.
