What is used to lag the atomization piping at the burner front on ships with steam atomization?

The use of epoxy coating to lag the atomization piping at the burner front on ships with steam atomization is primarily for its ability to provide a protective layer that shields the piping from environmental factors, such as moisture and corrosion. This is essential in a marine environment where the presence of saltwater can accelerate the degradation of metal components. Epoxy coatings also help in maintaining the thermal efficiency of the piping by minimizing heat loss, which is critical for ensuring that the steam remains at the desired temperature and pressure for effective combustion.

In contrast, insulating wool, fiberglass wraps, and ceramic insulation are more commonly associated with thermal insulation rather than protective coatings. While these materials can also serve a purpose in reducing heat loss and preventing surface contact burns, they may not provide the same level of protection against corrosive elements as epoxy coatings do. This makes epoxy the preferred choice specifically for lagging atomization piping where both insulation and environmental protection are key concerns.
