The recent research is focused on experimental study and mathematical modelling of the development of combustion dynamics at thermo-chemical conversion of biomass mixtures (straw pellets with crashed coal) with the aim to better understand the effect of electric field on the formation of the main gasification/combustion characteristics when co-combusting straw with crashed coal. The experimental study and numerical modelling of the electric field effects on the combustion dynamics, when co-combusting straw pellets with coal, were carried out to ensure wider use of straw as a fuel for energy production providing the electrodynamics process control. The mathematical model considers the electric field influence on the combustion characteristics using the approximation of 2D axially symmetric compressible swirling flow and chemical reactions with account of the development of A→B↔C kinetics (A – reactant, B – intermediate product, C – final product) downstream the cylindrical combustor.
