Gas turbine

  • The Turbec T100 micro gas turbine is highly instrumented to allow monitoring of the whole gas turbine cycle (temperatures, pressures, etc.), including extensive emissions analysis from the exhaust
  • Conventionally fueled by natural gas, conversions are in place to fire a range of other fuels, including biogas
  • The system comprises of a single-stage centrifugal compressor (with a pressure ratio of 4.5:1), a lean, pre-mixed combustion chamber and a single-stage radial turbine
  • The generator and shaft rotate at up to 70,000 rpm to generate high-frequency electricity that is exported to the grid
  • The counter-current water-gas heat exchanger is used to recover thermal energy; overall, the system has an electrical output of100 kW, with a thermal output of 165 kW (electrical efficiency ~30%; total efficiency ~80 %)
  • The significant dilution ensures high combustion efficiencies and low levels of emissions (CO, NOx, etc.)
  • The system has been modified to include exhaust gas recycle (EGR & Selective EGR), by which CO2 injections enable the examination of the impacts of recycling the exhaust gases on the combustion system, efficiency and emissions under different operating conditions
  • Post-combustion CO2 capture research from the turbine system is available, since the flue gas pathway is integrated into the on-site capture systems
  • Fuel flexibility research means that we are also investigating including hydrogen blending and other sustainable alternative fuels into our system
