Experimentally demonstrates stable combustion of low calorific fuel at high temperatures and low oxygen levels, suggesting practical implications for biomass energy.
The article presents the results of combustion of low calorific fuel as a product of biomass gasification process. Composition of the burned fuel was 13 % H 2 , 4 % CH 4 , 30 % CO, 13 % CO 2 , 40 % N 2 , which is very similar to composition of fuel obtained from wood gasification such as pellets. Investigations have been performed at room temperature and at conditions typical for High Temperature Air Combustion Technology, i.e. high temperature of the oxidizer (above the auto-ignition temperature level- from 800°C to 1100°C) and low oxygen concentration (below 21 % of O 2 as for conventional combustion - from 21 % by volume to 10 %). The experiments were supplemented and compared with numerical calculations performed using CFD ANSYS Fluent package. Experimental results show stable combustion process at high temperatures.
