Catalytic combustion system for a 10 MW class power generation gas turbine

摘要

In early 2000,GE Energy launched a program to develop a catalytic combustion system for one of its small power generation gas turbines,the GE10-1 engine.The target was to release to the market a new combustor able to guarantee NO_x emissions lower than 2.5 ppmvd(referred to 15 vol.% O_2).Today,a full-scale engine test campaign has been completed,during which measured NO_x emissions were as low as 1 ppmvd in the 90-100% load range.The article is aimed to illustrate the developed technology and the results obtained.The combustion system's configuration is briefly described,focusing on the XONON~R catalyst module installed.Reported data show combustion system's performances,mainly in terms of pollutant emissions and operability.Perspectives for future development of such combustion system are outlined.
