Combustion Dynamics of Biomass Mixtures with Microwave Pre-processing of Pellets


Abstract

Combustion dynamics of wheat straw mixtures with wood or with peat pellets is studied experimentally with the aim to provide a more effective application of wheat straw for heat energy production. Microwave pre-processing of pellets is used to activate their thermal decomposition and thus enhance the release and thermo-chemical conversion of combustible volatiles. Results of the complex measurements of the main flame characteristics and composition of the products show that the enhanced thermal decomposition of pellets provides improvement of the combustion conditions in the flame reaction zone completing thus the combustion of volatiles, increasing the flame temperature, the heat output from the device and energy efficiency and decreasing at the same time the mass fraction of unburned volatiles in the products.
