Experimental Evaluation of a Diesel Cogeneration System for Producing Power and Drying Aromatic Herbs

Experimental Evaluation of a Diesel Cogeneration System for Producing Power and Drying Aromatic Herbs

The focus of this work was to evaluate the thermal performance of a cogeneration system used to produce power and dry aromatic herbs. The waste heat from the exhaust gases of the diesel engine was recovered to heat air using a thermosyphon heat exchanger. The heated air was employed in a convective...
