Development of a Plasma-Dump Combustor for VOC Destruction

Abstract

Volatile organic compounds (VOCs) are gases with low calorific values produced from the painting or drying process whose stable combustion cannot be ensured by direct combustion. In this study, a novel plasma-dump combustor was proposed to remove the VOCs. The combustor is combined the concept of a plasma burner, a dump combustor and a 3D matrix burner. Therefore, it can achieve high destruction with low input energy and stable flame at low temperature.The toluene was used as a representative VOC. The toluene reduction characteristic was examined according to the total gas feed, toluene concentration, dump injector position, and 3D matrix heat accumulator. The toluene decomposition efficiency was 99.5%, and the energy efficiency was 447.2 g/kWh was at the optimum operating conditions.
