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. The exhaust gas flows over the tube stacks and heats the water, thus producing steam.
How do I start my exhaust gas boiler?
Operating Instructions for Exhaust Gas Boiler/Economiser
- Ensure drain valves are shut.
- Open air vent.
- Ensure circulating pump valves are open.
- Crack open inlet valve and close air vents when steam/water issues.
- Slowly open inlet/outlet valve.
- Check valves, flanges etc.
- Allow unit to warm through.
What is the difference between the auxiliary boiler and the exhaust gas boiler?
The heated exhaust gas from the engines (exhaust gas boiler) acts as a source of energy for generating this steam or thermal oil. Other auxiliary boilers are fired with oil or gas. A large number of valves are necessary to operate the boiler: Safety valves – for protection against excessive pressure.
Is gas central heating being phased out?
After going back and forth on the dates for quite some time, the UK government has now confirmed that gas boilers will be banned from new housing in 2025, and households will no longer be able to buy gas boilers from 2035.

What are the operating instructions for an exhaust gas boiler?
Operating Instructions for Exhaust Gas Boiler/Economiser These operating advices are not intended to be a comprehensive procedure, but merely an aide-memoire. The actual manufacturer’s instructions coupled with practical on-board experience will determine the actual sequence to be followed. i) Start up from cold Ensure drain valves are shut.
What is the recommended boiler exhaust velocity?
Recommended boiler exhaust velocity Exhaust Gas from Boiler Recommended Boiler Exhaust Velocity Recommended Boiler Exhaust Velocity m/s ft/s Ducts at minimum load < 4.0 < 13 Stack at minimum load < 5.0 < 16 Boiler with one-step burner (on – off) 5.0 – 8.0 16 – 26
Can I start a circulating pump with the exhaust gas boiler tubes?
The consequences of starting a circulating pump with the exhaust gas boiler tubes at elevated temperatures could be disastrous. On vessels with an exhaust economiser by pass valve, water temperature is a critical factor in preventing condensation and acid formation on the gas side.
