Environmental optimisation of gas fired engines in Denmark - potential

Potential and consequences of NO_x reduction by engine adjustments

This report and describes the potential and consequences of reduction of NOx emissions from natural gas fired engine based decentralised power plants in Denmark.
 
As a part of this project, emission measurements were conducted at two differ-ent Jenbacher engines and two different Caterpillar engines in operation on local combined heat and power plants in Denmark. The measurements supple-ment measurements from a previous project “ForskEL 10089”. During that project emission measurements were conducted on two Rolls-Royce engines and two Wärtsilä engines. External costs due to emissions were calculated as a part of the previous project as well.
