Development of Thermoelectric Exhaust Generator (TEG) Heat Recovery Systems for Marine Diesels

Thermoelectric waste heat recovery is an enabling technology that can be used to increase the overall plant efficiency of marine and industrial power plants by recovering heat from the exhaust that would otherwise be wasted. Using a thermoelectric generator (TEG), this energy can be recovered and converted to usable electricity using a solid state material. These types of materials could potentially be used in a myriad devices onboard marine vessels, which use heat exchanger technology extensively in the majority of its systems, in order to increase the overall plant efficiency. In order to understand and predict the outputs of TEGs when implemented in these heat exchange systems, a predictive model is required. Wallace et al. and Jin et al developed modeling techniques to predict the output of thermoelectric materials when differing temperature profiles are applied across the material. The experimental work described in this report shows the effort towards the production of data to validate this predictive model so that it can be used to develop TEGs to be used in the marine industry.
