At Chalmers University of Technology in Gothenburg, Sweden, research on Oxyfuel combustion has been performed since 2001. The 100 kW test rig was first built for gas combustion, but has been reconstructed and can now handle both gas and pulverised coal.
The test unit was specifically designed for the study of Oxyfuel combustion under real flue gas recirculation conditions. The flue gas recycle loop also includes a condenser enabling both wet and dry flue gas recycling. The theoretical work comprises process evaluation, CFD simulations and analysis and evaluation of in-furnace radiation and formation and reduction of gaseous species in-furnace as well as downstream of the furnace.
Change in radiative properties and reaction kinetics
The main objective of the current experimental work is to assess the change in radiative properties and reaction kinetics from air to Oxyfuel combustion. The experimental research builds partly on previous experience gained at the department in experiments on conversion of solid fuels.
