Exhaust Gas Boiler Suppliers
Every time a ship’s main engine runs, valuable energy is lost through hot exhaust gases. A marine exhaust gas boiler captures that waste heat and converts it into usable steam - supporting everything from fuel heating to freshwater generation and cargo handling. It’s one of the most effective ways to improve onboard energy efficiency without adding extra fuel consumption.
These systems, often referred to as boiler economizers for ships, are standard on many deep-sea vessels and are often combined with oil-fired auxiliary boilers. The result is lower operating costs, reduced fuel use, and better thermal balance across the ship’s energy network.
For shipowners and engineers, choosing the right exhaust gas boiler isn’t just about capacity - it’s about matching the unit to the engine's load profile, space constraints, and the vessel’s overall steam demand.
Key Features, Applications & Manufacturers
Most marine exhaust gas boilers are designed as vertical or horizontal economizer units placed in the main engine’s exhaust gas stream. As hot gases pass through the boiler’s tube bundle, heat is transferred to the water side, generating steam without any additional fuel.
Typical features include:
- Water tube or gas tube configurations, depending on space and pressure needs
- Integrated soot blowers to prevent fouling from exhaust particles
- Bypass dampers or control valves to regulate exhaust flow
- Flexible mounting options for funnel or deckhouse installation
- Compliance with class and safety standards (ABS, DNV, etc.)
Exhaust gas boilers are widely used on bulkers, tankers, container ships, and gas carriers where main engine loads are high and consistent. They form the core of many shipboard waste heat recovery systems, supporting steam-driven systems like cargo pumps, fuel heating, and freshwater generators.
Leading exhaust gas boiler manufacturers include Alfa Laval, Kangrim, and SAACKE. Each offers variations in size, steam output, and configuration to suit different vessel types and operational profiles.
