A New Way to Increase the Efficiency of an Atmospheric Condensing Engine

Year: 2025

Type: article

Abstract: The article examines the problems associated with the use of waste thermal energy. A new concept is developed on how to improve an atmospheric condensing engine by using low-temperature waste thermal energy, converting it into energy acceptable to the consumer (mechanical, electrical energy). The article presents a new scheme of a staged atmospheric condensing engine, thanks to which (based on preliminary calculations and recuperator verification experiments) it is possible to increase the efficiency of the condensing engine from 6.3% to 17%. At low temperatures (80–150 °C) this is a very high efficiency, since devices operating at low temperatures, for example, devices operating on the Rankine cycle, only have an efficiency of about 4.2–9%.
