Project of the new paddle steamer for the upper Rhine makes progress

E-mail Print PDF

DLM is currently working on the engineering and design of a new remote-controlled two cylindre compound condensing steam engine and an automatic boiler with a C02-neutral biomass firing system. The contract had been placed by a Swiss society named Pro Dampfer aiming to build an all-new paddle steamer for the upper Rhine between the Swiss town Schaffhausen and the German town Konstanz. Within the framework of this contact, several important milestones have now been achieved. A computer program for the thermodynamic calculatiion of the complex two cylindre compound condensing steam engine has been successfully completed. The calculated indicating diagrams coincide very accurately with measured diagrams. In a next  step the specific parameters of this project were used to desing the new steam eninge and the boiler. These are not yet manufacturing, but assembly drawings allowing precise knowledge of the requerements for power, mass and volume.

SS Spiez: Commissioning of the Steam Boiler

E-mail Print PDF

DS Spiez_Ausblasen der Dampfleitung

The new steam boiler of the screw steamer SS SPIEZ has been commissioned at the BLS shipyard in Thun as from March 9 to 11, 2020. By means of its electric preheating device located next to the boiler in the boiler room, the boiler was previously preheated electrically to 8 bar. In the afternoon of March 9 the oil burner has been ignited for the first time, followed by the usual commissioning and test procedures. Amongst these are the impressive blowing out of the main steam pipe. Following the cleaning of the main steam pipe, it is usually connected to the steam engine. As a result of the currently (too) low water level of Lake Thun, it is not possible to operate the steam engine which is directly coupled to the screw. For the test run of the new steam engine see: https://www.youtube.com/watch?v=2EmvZid8Hm0

The following drawing illustrates how the final design of the ship (Drawng: aardeplan ag - Architektur SIA 6340 Baar):

New Production of Boiler Safety Valves for Steam Locomotives

E-mail Print PDF

DLM will soon start another production run of boiler safety valves that were first produced for the new rack steam locomotives built in 1992 /96. Since then more than 30 safety valves have been manufactured for various steam locomotives in Austria, Germany and Switzerland. Until mid January 2020, it is possible to join the production run and profit from the moderat prices. For techniical data see: http://www.dlm-ag.ch/spare-parts/57-sicherheitsventil?lang=en
