With recent development in main engine technology,

the waste heat in the exhaust gas of the mainengine

is reduced significantly due to the de-rating and

high efficiency turbochargers. Coupled with slow

steaming this has resulted in steam output from

the main engine exhaust gas boiler being

reduced compared with overall steam demand.

To overcomethe short fall in steam, Greens Power can

retrofit (or supply for new vessels) a compact Exhaust

Gas Economiser suitable for use with 1, 2 or 3 auxiliary

engines.

Typically an Exhaust Gas Economiser is able to generate

approximately 500kg/Hr steam from the exhaust gas of a

single 1000 kW auxiliary engine.

This supplements steam output at sea and provides

steam in port when only the auxiliary enginesare

operating - Avoiding firing the oil fired boiler at sea and

reducesthe duty on the oil fired boiler in port.

For new ships positive influence on EEDI (Energy

Efficiency Design Index).

Comprises: • Compact Exhaust Gas Economiser, Circulating

Pumps, supply of associated flow and return pipes.

• A fully installed option is available asan extra including

any modification needed to existing boiler to enable

the steam space to be utilised.
