The Triogen ORC will be connected to the engines. These diesel engines could be running on bio diesel, diesel from crude oil, etc. The Triogen ORC converts the flue gasses (which is waste heat) into electricity.
When the engine drives an electrical generator, the electricity production of the system can be increased by 10% or more by using a Triogen ORC as a supplement to the engine. The ORC converts the waste heat of the flue gasses into electricity, so the extra electricity is produced without any extra input by way of extra diesel oil.
