Název v původním jazyce

Experimental and numerical research of plasma gas decomposition and gasification at IPP

Popis výsledku v původním jazyce

The research on perfluorinated compounds (PFCs) decomposition concentrates on efficient abatement of the most persistent PFC, i.e., CF4, and to observe a dependence of destruction and removal efficiency on gas mixed with CF4, concentration of CF4 and input arc power of the plasma torch. It was shown that the mixture with argon exhibits considerably higher destruction efficiency than that with nitrogen. The highest destruction efficiency was attained in the mixture CF4/Ar at 40 kW of torch power. The aim of the present numerical simulation of wood gasification is to find out distributions of physical properties of gas/plasma mixture in the reactor during gasification at higher plasma flow rate (v~3000 m/s) for three particle diameters and to compare them with corresponding distributions of physical properties at normal plasma flow rate (v~2600 m/s). Results of modelling show that at higher plasma flow rate the mole fraction of CO at the reactor exit is slightly higher for all three investigated particle diameters than in the case of normal plasma flow rate.n
