Combined Heat, Power and Mobility CHPM - An Alternative to diesel and battery-powered Vehicles

E-mail Print PDF

In combined heat and power processes, waste heat is often partly recovered for domestic heating and is therefore useful only in the cold season. Furthermore, as a result of climate change and better building technologies, the demand for heating energy is gradually declining.

Combining power and mobility opens up a range of new possiblities for waste heat recovery with no seasonal limitations. For instance waste heat from a gas power station can be used to produce hot water under pressure in a waste heat recovery boiler and the high pressure steam uesd to drive modern steam powered vehicles. In comparison with battery powered vehicles, water is much cheaper than lithium and there is no fading of perfomance over time nor from low temperatures. The life expectancy of hot water pressure vessels exceeds that of electric batteries by alarge margin.

The concept offers numerous applications. In energy intensive industries such as steel or cement, the entire works traffic (locomotives, trucks and so on) can be operated recovering waste heat, offering fuel cost savings and environmental benefits. Modern steam powered vehicles operate entirely free of emissions and therefore do not require emission control systems that are expensive to buy and heavy on maintenance.

The illustration shows the principal function of an airport tug operated by waste heat.

Light Oil Firing for Puffing Billy in Australia

E-mail Print PDF

The Australian tourist railway "Puffing Billy" is worldfamous. DLM received an order to convert one of their coal-fired NA-class locomotives to oil firing. This will eliminate sparks that prevent the use of steam locomotives in case of fire danger. The diesel locomotives that substituted the steam locomotives in fire hazard conditions have not been popular. The modernization has already begun. The outer appearance of the locomotive will not be changed. This method has already been successfully done with the conversion of the steam locomotive "Heidi".

The organizers replaced the bright yellow stripe by a golden one to match their carriages. On Saturday, August 12, 52 8055 run light engine along the river Rhine from Schaffhausen to Sissach, from where it hauled the  El Achai peace train over the old, steep Hauenstein line to Olten, continuing to Oensingen. The old Ed 2 x 2/2-Mallet locomotive took the train to Balsthal. After lunch the guests had been hauld back to Sissach likewise. 52 8055 spent the night at Sissach to be shown at the local festivities the next day. The return journey to Schaffhausen was light engine again. A photo can be seen at: http://www.dlm-ag.ch/en/steam-trips/previous-trips
