A Swiss society named Pro Dampfer intends to build an all-new paddle steamer for service on the river Rhein between the Swiss town of Schaffhausen to the German town Konstanz on lake Constance. No doubt the new paddle steamer will be popular with tourists enjoying the beautiful landscape along the meandering river, free of motor noise and exhaust emissions, but the project is also interesting from a pure technical background. As a world first, the new paddle steamer will be fuelled with local wood pellets, resulting in a CO2-neutral operation. However, the calorific value of wooden pellets is much lower compared to fuel oil, requiring an optimized steam engine. DLM now has to do the engineering for the entire drive: fuel, firing, boiler, steam engine, auxilliaries and paddle wheels.
