Boilers and Steam System The steam system plays a major role in energy efficiency of certain ship types (such as steam driven LNG ships) and a medium role in ships such as oil tankers carrying liquid cargo that require cargo heating or there is a need for cargo transfer using steam driven pumps but also need to generate Inert Gas for cargo tank cleaning, purging or tank top ups.Learn More
Oil Fired Boiler. Fountom oil fired boiler adopts matured technology that is most widely used. It is safe, high efficient (>83%) and automated, the steam accumulation speed is between 15 to 18 minutes. The pin tubes are welded in the boiler to ensure high thermal conductivity and high strength, also the robust smoke tube has long life expectancy.Learn More
