Abstract
A kinetic study on the combustion of a renewable energy resource -- pelletized biomass -- is carried out with the aim to obtain clean and effective energy production by minimizing the impact of the heat production process on the environment. To control the processes of biomass gasification, combustion of volatiles and heat energy production, a gradient magnetic field is applied to the flame base providing experimental study of the gradient magnetic field effect on the processes developing downstream the combustor. The joint investigation of the gradient magnetic field effect on the biomass combustion and heat energy production includes the estimation of the magnetic field effect on the formation of flame velocity and composition profiles, temperature of the flame reaction zone and heat production rate providing analysis of the magnetic field effects applicability to control the pelletized biomass combustion and heat energy production. The experimental results have shown that the gradient magnetic field enhances the mixing of the flame compounds, so increasing the combustion efficiency and completing the burnout of volatiles.
