Marine Boilers - Marine Engineering Knowledge Part 1

3/7/2017 · The main function of a safety valve is to relieve pressure. It is located on the boiler steam drum, and will automatically open when the pressure of the inlet side of the valve increases past the preset pressure. All boilers are required by ASME code to have at least one safety valve, dependent upon the maximum flow capacity (MFC) of the boiler.

14/7/2010 · Introduction: Marine Boiler Safety Valves. The pressure setting of the superheater safety valve should be less that the designed pressure of the boiler, i.e. less than that of the steam drum safety valve, to ensure flow of steam through the superheater under blow off conditions. The pressure setting of one steam drum safety valve should be same as
