Heat-to-power

The option allows to recover heat into electric power. The system uses Organic Rankine Cycle (ORC). The working fluid with low evaporation temperature is heated and evaporated, and then passed through a turbine where it is finally re-condensed. 

There are two options possible. The one with hot water. Efficiency 8%. 1 MW heat from cooling of the engine is converted to extra 80 kW of electric power. The other option with heating oil is more expensive but efficiency is 20%.
