Voith Turbo
Voith SteamTrac for More Efficient Energy Utilization Voith Turbo is presenting a new waste heat recuperation system that reduces fuel consumption and harmful emissions. In the Voith SteamTrac, heat losses from the drive engine are converted into mechanical energy. Some of this energy is redirected into the driveline. Voith SteamTrac builds on a closed steam circuit. In the hot exhaust stream of the diesel engine, steam is generated via a heat exchanger and fed to a piston expander. This means that exhaust heat created during the combustion process is converted into usable torque and redirected to the drive. As a result, fuel consumption and consequently CO2 emissions can be significantly reduced and the engine output is increased without the need for extra fuel. Conventional engines can utilize only 40 percent of the energy in the fuel during the combustion process. This means that 60 percent of the energy is lost either as heat or in the cooling water. While there are already several efficient heat recuperation systems for high-performance engines, there is still no adequate unit for smaller marine applications. For combustion engines with a power consumption between 300 and 2 000 kW, a steam turbine would be ineffective. Apart from that, such an investment would also not be financially feasible. Voith Turbo developed the SteamTrac, in order to provide an efficient and economic solution also for smaller marine applications. The SteamTrac reduces fuel consumption and CO2 emissions by 4 to 12 percent. The system can be used in marine and industrial applications, as well as in rail vehicles. Voith Turbo, the specialist for hydrodynamic drive, coupling and braking systems for road, rail and industrial applications, as well as for ship propulsion systems, is a Group Division of Voith AG. Voith is setting the standard in the paper, energy, mobility, and service markets. Established on January 1, 1867, Voith is now one of the largest family-owned businesses in Europe, with 39 000 employees, 5.1 billion euro in sales, and over 280 locations worldwide. Voith is an official partner of the initiative "Germany - Land of Ideas". |
