In this work, the effect of viscosity on the combustion efficiency
in a micro gas turbine is investigated by changing the injection
temperature of a viscous fuel. Here, the fuel viscosity at the pressure-
swirl nozzle is used as measure for the spray quality, while
CO emissions indicate the combustion efficiency. The main goal
is to determine the sensitivity of the combustion process to an
increase in fuel viscosity and to identify a typical maximum viscosity
for which the atomization is still acceptable
