Research at the atmospheric Research Entrained flow Gasifier REGA focusses on the gasification behavior of biogenic and anthropogenic liquid and suspension fuels. The axially movable burner construction enables radial profile measurements of temperature and gas phase composition at variable burner distances. Applying laser-optical diagnostics allows for the determination of local distributions of droplet sizes and velocities, as well as the characterization of reaction zones. The experimental data serve as basis for modelling the thermo-chemical processes under entrained flow conditions and for validation of numerical models simulating the gasification process.
