2025-01-27

Dmitry Pashchenko gave a lecture-seminar at the Technion entitled: "THERMOCHEMICAL EXHAUST HEAT RECUPERATION AS A PATHWAY TO HIGHER EFFICIENCY OF HEAT ENGINES" The abstract of seminar: The Applied Thermal Engineering Laboratory at the Guangdong Technion – Israel Institute of Technology was established in 2022 with the main goal of studying energy conversion in fuel-consuming equipment and the associated problems in thermodynamics, heat and mass transfer, and combustion. The primary focus is on investigating promising ways to improve energy efficiency – specifically, thermochemical exhaust heat recuperation – while also emphasizing the use of carbon-free fuels, such as ammonia. In the first part, I will describe the concept of thermochemical exhaust heat recuperation (TCR) and my background in this topic, particularly its application in industrial furnaces and gas turbines fired with methane. In the second part, I will focus on specific results related to gas turbines with thermochemical exhaust heat recuperation – specifically, the chemically recuperated gas turbine (CRGT). In the third part, I will present the current and future research in my laboratory aimed at utilizing ammonia in gas turbines and developing a compact and efficient fuel reformer based on Triply Periodic Minimal Surfaces (TPMS).
