Technology options and plant design issues for fuel-flexible gas turbines

Jenny Larfeldt     Siemens Industrial Turbomachinery AB, Finspong, Sweden


Gas turbines are continuously flowed through machines with high power densities. Their application area is widening from natural gas-fired base-load operation to fuel-flexible base load or plants for flexible operation. Gas turbines can offer low emissions in a wide operating range with the prevailing lean, premixed combustion systems. Gas turbines can be integrated in plants for power generation and sometimes heat. A natural gas-fired gas turbine in a combined cycle has less than half the CO2 emissions in grams per produced kWh compared to a coal-fired conventional plant. With carbon capture ...
