All basic or conventional refractory materials are primarily used to prevent gas and fire from escaping from the boiler furnace. Selecting a refractory type should be based on the area of usage, the temperature, and the operating conditions it will be exposed to, such as flue gas, slag, and ash (if located inside the boiler/furnace area).

Drying refractory is critical for strong, long-lasting refractory applications. Unfortunately, standard refractory dry-out schedules, provided by all refractory manufacturers with their products, are difficult to apply to refractory used on a steam-generating boiler. These standard dry-out schedules are generic and require temperature monitoring rarely found at power plants, where …
