Particle emissions are especially formed in heavy fuel oil applications due to the ash content of the fuel and its combustion characteristics.
Two different systems can reduce these already low particle emissions further: 

Electrostatic precipitator (ESP)

For high exhaust gas temperature applications, the electrofiltration using the electrostatic attraction of ionized paticles is the best choice.

Bag filtration

Where low exhaust gas temperatures are given, for example in CHP applications, bag filters are applicable. If necessary, these can be easily combined with a DeSOx system. 

Emission monitoring

To fulfill local regulations regarding proof of exhaust gas emissions, and to ensure an ideal operation of exhaust gas treatment units, MAN will choose the best solution for your demands in price and practice .
The function and reliability of these systems has been proven in a couple of installations.
