Technical data

Description
The SMIT GAS™ DGin inert gas generator (IGG) utilizes the exhaust gas from the diesel engine as combustion air for its Ultramizing® burner. As the oxygen content is already low(ered) in the exhaust gas (normally approx. 13% O2 compared to approx. 21% O2 in atmospheric air), less fuel is required for the DGin generator to produce the necessary quality (> 5% O2) of inert gas for tank inerting, and fuel savings of up to 35% for the IGG are
possible. This means reduced emissions and a sharply reduced fuel bill.

The SMIT GAS™ DGin inert gas generator plant consists of three main components:

• A venturi scrubber for removing soot
• A packed column with demister for removing SOx and droplets
• A flue gas fan that supplies the low O2 content diesel exhaust to the inert gas generator

The generator is equipped with Aalborg Industries’ Ultramizing® combustion system and uses the combustion air or diesel exhaust gas for atomisation. An oxygen control system guarantees the correct combustion of the diesel exhaust gas.

SMIT GAS™ DGin is based on experience gained from the Combinert® combined inert gas generator and boiler flue gas treatment system originally developed by our company in 1984.
