Temperature Runaway in a Pulsed Dielectric Barrier Discharge Reactor

TL;DR

This study investigates the thermal behavior of a pulsed dielectric barrier discharge reactor, revealing a temperature runaway at 300Hz likely caused by a resonance effect, with implications for reactor stability.

Contribution

It provides experimental insights into the temperature dynamics and identifies a novel runaway phenomenon at specific frequencies in dielectric barrier discharge reactors.

Findings

Thermal behavior follows a first order model.

Runaway temperature observed at 300Hz reaching 170°C.

Resonance may cause sudden power and temperature increase.

Abstract

This paper reports on experimental measurements of the gas temperature in a dielectric barrier discharge reactor powered by a high voltage pulsed signal. It is shown that the thermal behavior of the reactor follows a first order model. However, an unexpected runaway phenomenon was observed at a frequency of 300Hz. A sudden increase in the power source and consequently in reactor temperature which reaches 170{\deg}C is observed. This behavior is discussed in terms of input power variation with temperature, possibly due to a resonance phenomenon.
