7 Performance
Typical examples of exhaust gas heat exchanger performance. The figures below are a general
guide only and are not based on any particular natural gas engine. They assume an air/fuel
ratio of 10.23 : 1 by volume, a fuel consumption of 0.34m
3
/kWh (measured at 1.013 bar and
15°C) and an exhaust gas temperature of 600°C and a water temperature of 80°C.
Figures are based on new and clean conditions.
