Modelling the Effects of Operating Conditions and Alternative Fuels on Gas211 Turbine Performance and Emissions

摘要

With the increasing attention to gas turbine exhaust gas pollution, a need has211u001eemerged to assess effects of a variety of operational variables on the emission 211u001elevels. An effective approach to address this need is to integrate combustor 211u001eemission models in gas turbine performance models. NLR's generic gas turbine 211u001eperformance simulation environment (GSP) has therefore been extended with a major 211u001eexhaust gas emissions NOx, CO, UHC and Smoke. First, GSP's gas model has been 211u001eextended to include a detailed description of gas composition including the 211u001eparticular emission species. Second, a new generic multi-reactor combustor model 211u001ehas been developed for detailed modeling of the processes in a combustor. The 211u001ecombustor model is set up by defining a number of reactors modeling combustion.
