Modelling of gasification of crushed wood in thermal-plasma chemical reactor

Popis výsledku v původním jazyce

The paper presents numerical simulation of gasification of crushed wood using a unique plasma torch stabilized by argon and water vortex in a plasma chemical reactor. The water-argon DC-plasma torch offers the advantage of low plasma mass flow rate, high enthalpy and temperature allowing achievement of an optimal conversion ratio with respect to syngas production compared to other types of plasma torches. Numerical model was created in the ANSYS FLUENT software package. Results of gasification and syngas production from crushed wood show that gasification efficiency and syngas production decrease slightly with increasing particle diameter, while thermal inhomogeneity in the reactor volume is strongest for the largest particle diameter and decreases with decreasing wood particle size. High syngas content (~90%) was achieved for all studied currents (400-600 A) and wood particle diameters (0.2 – 20 mm).n
