Voith Turbo SteamTrac waste heat recovery system in rail car decreases fuel consumption by 4-12%

Voith Turbo SteamTrac waste heat recovery system in rail car decreases fuel consumption by 4-12% 30 October 2011 Voith Turbo recently reported the test results from a SteamTrac (Steam Traction) waste heat recovery system installed in a rail vehicle of SWEG Verkehrsbetriebe Breisgau Kaiserstuhl, Germany showed a decrease in fuel consumption and CO2 emissions by 4 to 12%, depending upon the driving profile. Voith developed SteamTrac to target marine and industrial applications as well as rail vehicles. Steam is generated from exhaust heat via a heat exchanger and fed to a piston expander to produce additional mechanical energy, which is then redirected straight to the driveline.

The single-car diesel railcar built by Waggon Union Berlin dates back to 1...
