Abstract

The main purpose of this study is to obtain clean and efficient thermal energy by producing a direct current electric field to the flame reaction zone and to provide the thermochemical transformation of biomass (wood) particles controlled by the process produced in the field. In this regard, a mathematical model for modeling the thermal decomposition in the presence of an electric field, as well as, an experimental work has been developed. The equations of aerothermochemistry are coupled to balance equations for densities of charged species, and a Poisson equation for electrical potential is solved. The results obtained show that the presence of the electric field significantly improves the stabilization of the flame. The electron injection affects the char combustion process significantly. The field enhancement the combustion characteristics, and the flame reaction zone of field induced ion wind on biomass thermal decomposition was analyzed.
