Burner, Pilot, and Superheater Restoration
Installing Insulation In Burner Shell
To protect the steel parts of the burner several coatings of high-temperature black paint were applied to all surfaces. Once the parts had dried they were then assembled with the proper insulation applied. Then a final coat of high-temperature paint was applied to cover the fasteners that hold everything together.
Originally Stanley Steam cars relied on asbestos for insulation of the burner, boiler, and steam piping. Today the replacement insulation is "refractory ceramic fiber". This form of insulation is spun from Alumina (Al2O3) and Silica (SiO2) and is available in various forms including blankets, felt, and paper. Generally the blanket form is used for insulating cavities such as the walls of the burner and the smokebox. The felt can be used for the sides of the boiler while the paper form provides a strong durable top covering to the outside surfaces of the boiler. Pipes may be wrapped with various widths of ceramic fiber tapes and some manufacturers offer ceramic fiber sleevings that can be slid over steam tubing to insulate it.
