Enhanced locomotive efficiency through waste heat recovery

Efficiency is in demand the world over as fossil fuel prices are forecast to rise significantly over the coming decades. This will increase pressure on operators of diesel engines, whether for stationary or mobile applications. Stationary applications typically have the advantage of larger engine capacities and fewer space constraints for Implementing/retrofitting Waste Heat Recovery Systems (WHRS). Therefore WHRS tend to be state-of-the-art in stationary power plants and many industrial processes, while implementing WHRS in mobile applications presents some technical hurdles and has so far been un-economical. This is now changing due to the increasing cost of fuels and to the latest advances in technology. This paper presents a number of technical solutions for WHRS in locomotive diesel engines and highlights the main benefits, costs and technological challenges.
