Exhaust gas Boiler recirculating pump takes Boiler water from condenser on circulation through Exhaust Gas Boiler, needs higher pressure & flow to pick up the heat ( as internal volume of the Exhaust Boiler is quite less compared with the main boiler) and delivers to deaerator. Hence Exh Gas boiler needs to be at a higher pressure

First, the safety valve of the boiler should lift so that the water flow in the economizer should not stop in case of high pressure or else tubes of economizer will burn due to lack of water flow.

Above article was very informative. I am an old time Chief Engineer, presently a faculty member of a teaching college.

I have a question. Can you tell me the “reasons as to why Exhaust Gast Economiser Safety Valve setting is set at a slightly higher pressure than the Auxiliary Boiler’s Safety Valve setting?”

i know for sure it is set at a higher setting; but for what reasons I do not know!

And also by how much % more than the Aux. Blr. Safety Valve.

I am very happy that nowadays there are so many marine sites helping students. In our days there were only books, which we could’n’t afford, and very few marine colleges and that too only in big cities.

I appreciate all your hard work and I wish you success in all your endeavour.

Thanking You,
With warm regards,
Mohammed Khan
