Exhaust Gas Boilers And Economisers working procedu

Exhaust Gas Boilers And Economisers Arrangement Auxiliary boilers on diesel main propulsion ships, other than tankers, are usually of composite form, enabling steam generation using oil firing or the exhaust gases from the diesel engine. With this arrangement the boiler acts as the heat exchanger and raises steam in its own drum.

Boiler Economizer Exhaust Heat Recovery Syste

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. Combustion
