ALTAS: Advanced low NOx flexible fuel gas turbine combustion, aero and stationary (10426)

Gas turbine combustion is the most important energy conversion method in the world today. Using gas turbines, large scale, low emission energy production is possible. Nitrogen oxide emissions are one of the most important technology drivers for combustion systems today. For land based engines, low NOx emissions can be achieved by very lean premixed combustion (dry low NOx). For most aero applications, gas turbines are the only option to achieve the required thrust. It is expected that fuel composition will change in the future. This is due to depletion and independency of oil reserves and the greenhouse effect of burning fossil fuels. New fuels will be generated from biomass, landfill, waste and coal. Coal gasification with CO2 sequestration looks very promising.

This results in gaseous fuels with high hydrogen and carbon monoxide content with various fractions of diluents. Liquid fuels for aero applications will contain larger fractions of synthetic fuel, such as generated through the Fischer-Tropsch synthesis derived from biomass.

This project is aiming to improve on turbulent combustion models for computational fluid dynamics in cooperation with Siemens Orlando (stationary high hydrogen application) and Rolls-Royce Berlin (aero FT-fuel case). The method of flamelet generated manifolds (FGM) will be used, improved, extended and validated for the current applications.
