Marine Industry

Installation of cleaning technology on a marine boiler is necessary to prevent the build-up of deposits, not only to maintain the heat transfer design parameters, but also to reduce the possibility of soot fires. The latter is viewed as particularly critical by major marine insurance companies since the loss of a vessel has significant commercial consequences.

Solution

In view of the tight space restrictions, sootblowers of short overall lenghs are more commonplace. The heat recovery sections are generally of the finned tube design and rotating nozzle blowers are selected as they require less exterior space. The flue gas temperatures and the tube bank configuration prevailing at the points of installation determine the blowing tube materials a well as the number of nozzles required in each installation.

Advantages

• Minimises the risk of fire whilst in service
• Reduces maintenance cost and erosion
• Optimal cleaning of heating surfaces
