A further subclassification of scotch boilers describes the end closure opposite the burner end of the boiler. A wet-back means the end closure is water cooled and a dry-back means the end closure is not water cooled and relies on fire brick, refractory, or a combination of both to prevent the end closure from overheating.Get Price
