In response to stringent environmental legislation and customer demands for improved thermal efficiency, ABB ALSTOM POWER UK Ltd has introduced the 13.4MW Cyclone gas turbine engine. In this machine higher efficiency is achieved by increased firing temperature and pressure ratio. In order to meet the environmental considerations the Cyclone is supplied with Dual Fuel DLE combustion system as standard. Successful operation of the combustion system required a careful balance between the component life and low emissions performance. The combustor performance specification included targets for the following parameters:-

• Low emissions, NOx, CO, UHC and smoke, on both gaseous and liquid fuels without water or steam injection

• Good turn down ratio

• Controlled combustor outlet temperature profiles, both OTDF and RTDF

• Low dynamic pressure fluctuations

• Reliable ignition and fuel change over on both gas and liquid.

• Reliable transient response

This paper describes the design and validation work undertaken in order to achieve these challenging targets. It is shown that these targets are not only achieved but in some cases exceeded resulting in an economical and environmentally sound combustion system.
