How to Destroy a Boiler -- Part 1
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. A plastic refractory material is generally found inside the boiler furnace and is designed to resist higher temperatures and chemical or abrasive attack. According to ASTM C-64 castable or conventional refractory is divided into 2 classifications alumina-silica
