Combustion processes in a biomass fuel bed - experimental results

摘要: Combustion processes in a biomass bed are investigated experimentally. Special attention is paid to the influence of primary airflow and particle properties on ignition front, its temperature composition gas leaving front. Two test rigs have been built: large rig same size as boiler for domestic use small laboratory rig. In both front moves opposite direction airflow. Three combustion regimes identified: sub-stoichiometric regime with incomplete consumption oxygen, complete oxygen an over-stoichiometric regime. The results show that fuel higher density thermal conductivity (but other respects similar fuels) has wider where cornpletely consumed. If increased (for quality) range this becomes shorter starts at
