Microwave Heating at High Pressure

In conventional thermal processing, transferring high heat fluxes through physical vessel walls frequently causes superheated boundary layers, localized coking, and thermal degradation of sensitive fluids. Direct microwave heating eliminates these boundary constraints by coupling electromagnetic energy volumetrically throughout the process medium, enabling rapid and uniform temperature escalation.

However, applying microwave fields under extreme thermodynamic conditions—such as elevated pressures up to 25 bar and temperatures reaching 400 °C—presents substantial engineering challenges in cavity design, dielectric property matching, and mechanical integrity.
