What are the precautions to be taken while steam pressure is reduced for a process?

Fully open bleed valves, using reduced system pressure, to remove any remaining condensate. Activate cold steam piping slowly at reduced pressure and with trap bleed valves continuously open. To prevent possible condensate accumulation, place blowdown valves before and after a vertical rise.

Why are boilers used on ships?

Boilers are one of the essensial equipments onboard ships. It’s purpose is to provide heating to the the main deisel propulsion engine, to the bunker F.O. The steam generated by the boiler can also be use for cleaning, and heating of the seawater in the freshwater generator thus evaporating it to make it potable water.

How does a boiler on a ship work?

The main job of a boiler is to make high pressure steam. The feed water supplied to the boiler drum utilizes the heat of the energy released by burning the fuel. This energy of the burning fuel is stored in the form of steam with high temperature and pressure.

Where is the boiler on a ship?

On a ship, the fire room, or FR or boiler room or stokehold, referred to the space, or spaces, of a vessel where water was brought to a boil. The steam was then transmitted to a separate engine room, often (but not always) located immediately aft, where it was utilized to power the vessel.

Where is steam used on ship?

Steam is also used in ships to cater to other heating requirements, some of which are listed below: Used as a heat exchange medium in Heavy Fuel Oil purifiers, Light Diesel Oil purifiers, and Lube Oil purifiers. Steam is used as a heating medium in booster modules. To pre-heat the main engine jacket cooling water.

Where is pressure reducing valve located?

Pressure Reducing Valves. The Pressure Reducing Valve is designed to regulate the high water pressure supplied by the city to a level that is safe for homes. It is installed on the main water line. This is most commonly in the front flower bed, but it could also be behind an access panel in an inside wall.
