brother, the jacket cooling system has a deaerator tank. Whats inside this deaerator tank? can you give us a video? i have never seen the inside of it.
During maneuvering, once Main engine starts,we crack open 1 TK heating..so condensate will come into the cascade TK...my remedy for that is b4 departure, I only fill up cascade TK 70%...once going to overflow I make blowdown little bit...
If there is no rupture in the steam preheater line then also their is a cascade tank overflow during maneuvering what are the probable reason please reply.
The other reasons are also applicable, but since the ques is of Maneuvering, then focus on rupture point. I will try to find out if there is any other reason apart from rupture.. Thanks.
One more which normally occurrs , a At Port all tank heating and dump steam lines are shut,so water level goes down in hotwell and water is topped up , during maneuvering we use to open these valves one by one as boiler is running and economiser is also in use, So water which was condensed in lines , and dump condenser will now come in the system and it will overflow the hotwell.
Here I can't do anything and everything. Lectures are always in English. If u don't understand simple English that's not my problem. Basic English is required on ships.
Thnk u for the more information videos......u help to make our carrier ❤️❤️❤️
Thanks alot..
@@CLASS4ORALS I refer ur channel to our mariners whatsapp group
Thanks alot for this..much appreciated..😊👍👍
on my ship the preheater pump discharge pressure was 1.8-2bar, and we use steam of 4 bar. so how jcw will go into steam side?
Pratik bhai, We are throttling steam to crack open hence it's pressure falls below jacket water pressure
Nice job. Thank you very much for informations :)
Welcome so much.

What action we have to take during this scenario?
