Only someone with the proper training should attempt to shut down the boiler.

Once a boiler is cool enough to touch, you can diagnose the source of the crack. Cracked tubes and fuel lines may be a result of corrosion, rust and age. In other cases, a faulty pressure valve will allow too much pressure to build up, causing the boiler to rupture. Rust and physical breakage are the most obvious signs of damage, though the nature of the crack may require a repair professional to diagnose the problem for less obvious causes.

What is Refractory?
Boiler refractory is heat-resistant materials that are used to line the boiler to help it retain heat. This prevents thermal loss during boiler operation. It also helps the boiler retain heat even when it is not firing.
What Causes Refractory Failure?
While refractory tends to be resilient in nature, it is in fact considered a consumable. This means general wear and tear over time will eventually cause it to fail. This is due to the high pressures, high temperatures, slag and chemicals in a boiler system.
Signs Of Failure
According to Honiron, “Common signs that the refractory material of your boiler may need repair include fractured or broken refractory tiles. You may also see evidence of boiler leaks, difficulty in opening and closing refractory doors, and damaged seal joints.”
Boiler Refractory Repair Basics
Before we get into how to repair refractory cracks, it is important to realize that not all cracks are bad. In fact, some cracks are normal. The normal cracks are small and close up during the heating process and open again during the cooling process. This is due to thermal expansion and contraction.
