Boilers, aheadturbines, turbine engines, different kinds of equipments as well as all kinds of pipelines containing high temperature media are installed in the compartment of steam-powered vessels, which is located at the bottom floor of the vessels with poor ventilation, therefore, high room temperature inside the compartment of steam-powered vessels is the major challenge to vessel designers. Insulation materials with high performance are helpful for effectively reducing the heat of the equipments and pipelines inside the compartment, which not only improves economic efficiency of the power system, but also fundamentally brings the temperature within the compartment under control and decreases the cost for ventilation.
