Advanced Locomotive Exhaust Gas Simulator to Fine-Tune Energy Recovery and Conversion Systems

This investigation expands on findings obtained in the technical and economic performance analysis of Waste Heat Recovery Systems applied to locomotive engines executed under the Transit IDEA Project 67 (TR67). Activities conducted under TR81 were dedicated to the development of a cost-effective, locomotive-scale, exhaust gas simulator to fine tune WHRS’ components customized for operation at locomotive conditions. The project’s accomplishments include the successful implementation of a scaled Extended Combustion Chamber (ECC) to enable low-cost testing of various High-Pressure Heat Exchangers (HiPHEX) configured to non-invasively retrofit locomotive equipment. The locomotive scale ECC resulting from this investigation is capable of reaching in excess of 5MW of thermal energy represented by the locomotive exhaust gases. Results indicated that the computer codes predicted the HiPHEX and the exhaust gases thermodynamic characteristics with satisfactory accuracy, thus enabling further scaling-up of the ECC to generate exhaust gases at conditions replicating actual locomotive exhaust gases at all notch settings. Project TR81’s impact on practice manifests as improved transit capital operating efficiency, while protecting public safety and the environment, in addition to promoting energy independence. TDR plans to continue the optimization of the locomotive exhaust gas simulator to execute long-term reliability and endurance testing of WHRS components and to further investigate features targeting more aggressive pollutant emissions reduction methodologies enabled by the retrofitting of WHRS with locomotive equipment.
