121452 - Optimised Pilot Burner With Intelligent Control to Achieve Sub 9 PPM Emissions for Siemens Energy SGT-300-1S 7.9 MWe Engine 

In support of decarbonisation, Siemens Energy Industrial Turbomachinery Ltd developed the Low Effective Area Pilot (LEAP) burner for its SGT-300 engine to produce ultra-low emissions for a wider range of engine load. The LEAP burner is a minor design change from the standard pilot burner, with the size of the pilot gaseous fuel injection holes optimised. To validate the design change, a single-shaft SGT-300 engine (SGT-300-1S) configured with the LEAP burners and the rest of the combustion hardware as standard was tested at various operating conditions including natural turndown as well as with turndown control temperature at part load by Variable Guide Vane (VGV) modulation. An intelligent control algorithm for combustion was used, and its settings for the LEAP burners were further optimised by pilot split mapping during engine testing. The same engine configured with standard pilot burners was also tested to provide reference data. Extensive instrumentation and measurement equipment were used in the engine test to measure NO_x, CO, and Unburnt Hydrocarbon (UHC) emissions and combustion system performance, such as fuel supply pressures and temperatures, combustion hardware metal temperatures, and combustor and casing dynamics pressure. Engine test results show that with the optimised intelligent control for combustion, a wide load range of sub 9 ppmvd emissions can be achieved for the SGT-300-1S engine with the LEAP burners.
