Development of a gas turbine fuel nozzle for DME and a design method thereof

► We propose a DME nozzle with low NOx/CO emissions and anti-flashback characteristics. ► The nozzle design is based on the Wobbe Index and the combustion properties of DME. ► NOx at 60 kW is reduced by 8.9% and 23.6% for DME and methane respectively. ► High CO problem is resolved by achieving under 5 ppm for all test conditions.
