Dillingen municipal utilities convert to dual-fuel operation

Since subsidies for palm oil were cancelled by the German government and the operation of diesel engines with palm oil is no longer profitable, generator sets are increasingly being converted to natural gas or biogas. The municipal energy supplier from Dillingen an der Donau has converted to dual-fuel with the support of HEINZMANN.

The challenge:
The MAN engine used by Stadtwerke has a speed of 1500 rpm and a rated electrical output of 400 kW. Conversion to dual-fuel is intended to save costs and reduce emissions.

The solution:
As a result of the conversion, the diesel injection is now only 30 % and contributes 120 kW to the output. Natural gas accounts for 70 % of the energy supplied and thus contributes 280 kW to the output. Thanks to the conversion to dual-fuel operation, the municipal utilities not only benefit from savings in fuel costs, but also contribute to reduced emissions and less environmental pollution.
