Marine boiler safety valve easing gear fitted on a ship boiler
Generally on boilers used on ship two safety valves are fitted. These safety valves are o/hauled in dry-dock and set to open at 3% more than the max allowable pressure, in presence of a surveyor. In case of economiser safety valves the valves are set by the chief engineer at sea and the surveyor is informed.

State The Function Of Superheater And Economizer. - Discuss
Function of Superheater : The steam produced in the boiler is not dry but contains some moisture. Such wet steam can damage/corrode and reduce the efficiency of the plant. Hence before supplying wet steam to turbine, it is passed through super-heater, where it is dried and superheated by the flue gases.
