Temperature Calculation of Plasma Generator for Waste Disposal

Abstract:

The jet temperature of the plasma generator for waste disposal reaches as high as 10000K so that it is difficult to measure directly. By constructing a digital plasma measurement system, the operating parameters of plasma generator can be precisely controlled and measured. According to energy balance principle, the mathematical model was determined to calculate the average enthalpy at the plasma generator exit plane, and the average temperature and its distributions were obtained. Influence of different gas compositions on plasma jet characteristics was studied. The results show that, at the plasma generator exit plane, the maximal temperature and average temperature of argon plasma jet is about 18794K and 10193 K respectively, while that of argon-hydrogen plasma jet is about 22358 K and 12100 K.
