    Types of Exhaust Gas Boiler (EGB) Fires and Ways to

    Mar 06, 2020 · An Exhaust Gas Boiler is a type of heat recovering system on ships which allows the exhaust heat of the main engine to produce steam while going out in the atmosphere. Every system, which is operated at high temperature, always has a risk of fire. This applies to EGB which has the inlet temperature of exhaust gases @ 300-400 deg. C.

    Boiler Economizer Exhaust Heat Recovery Systems

    SYSTEM FUNCTION Exhaust heat from combustion typically leaving the stack and into the atmosphere is instead transferred from the exhaust stream by means of a Cain economizer. This lost BTU is now captured and saved to various heat sinks such as boiler feedwater, cold makeup water, process water, swimming pool water, glycol, and thermal fluids.

    Feb 03, 2019 · Do you mean the one on the exhaust side of the boiler? The idea is to drain any condensation out of the boiler into a bilge tank to avoid it running down and into the main engine turbochargers. If the boiler tubes leak, it’s a handy visual device to let you know they are leaking as the seal pot will overflow.

    The number of boiler passes represents the number of times the hot combustion gasses travel across the boiler (heat exchanger). A boiler with two passes provides two opportunities for the hot gasses to transfer heat to the water in the boiler. A 4-pass design provides four opportunities for heat transfer.

    Economizer - Wikipedia

    They are a device fitted to a boiler which saves energy by using the exhaust gases from the boiler to preheat the cold water used to fill it (the feed water). Steam boilers use large amounts of energy raising feed water to the boiling temperature, converting the water to steam and sometimes superheating that steam above saturation temperature.
