Low-Calorific Fuel Mix In A Large Size Combined Cycle Plant
(2009) 54th ASME Turbo Expo 2009 p.367-376- Abstract
- This paper will address the effects of mixing low-calorific fuel in to a natural gas fuelled large size combined cycle plant. Three different biofuels are tested namely; air blown gasification gas, indirect gasification gas and digestion gas. Simulations have been performed from 0-100% biofuel natural gas mixtures. The biofuel impacts on the full cycle performance are discussed. Some more in-depth discussion about turbo-machinery components will be introduced when needed for the discussion. The compressors pressure ratio will increase in order to push the inert ballast of the low calorific fuels trough the turbine. Despite the increased expansion ratio in the gas turbine, the exhaust temperature raises slightly which derives from changed... (More)

The compressors pressure ratio will increase in order to push the inert ballast of the low calorific fuels trough the turbine. Despite the increased expansion ratio in the gas turbine, the exhaust temperature raises slightly which derives from changed gas properties. The work is based on an in-house advanced off-design model within the software package IPSEPro. Sweden's newest plant "Oresundsverket", which is a combined heat and power (CHP) plant, is used as a basis for the Investigation. The plant is based on a GE Frame-9 gas turbine and has a triple-pressure reheat steam cycle. (Less)
