In the context of a research project launched in 2006 (partially funded by Regione Veneto, a local institution in the Northeast of Italy), ENEL and GE Oil & Gas are developing an innovative “zero emission” gas turbine cycle suitable for power generation. The gas turbine, a GE10-1 model, is manufactured by GE Oil & Gas and features a single can silo-type combustion chamber. A hydrogen-fuelled GE10-1 prototypical unit has been installed in Fusina (Venice), at ENEL’s coal-fired power plant, and has been in operation since September, 2009. The prototypical unit is equipped with a diffusive flame combustor, and the NOx emission level is kept below contractual limits by means of steam injection. In the mean time, further research activities have been carried out to develop an upgraded diffusive combustor, to be operated with 100% H2 and with NOx emissions reduced to below 50% of the current contractual limits. CFD has been extensively used (in cooperation with several Italian universities and research centers) in order to model and assess the behavior of the prototype combustor, and to define the preliminary design of modified burners and liners. Subsequently, the most promising configurations were engineered, procured and tested on a full-scale full-pressure combustion rig at ENEL’s experimental facility in Sesta (Tuscany). The behavior of alternative components has been monitored, with a focus on metal temperatures, pattern factor, pressure pulsations, and NOx emissions, and the performance has been compared to that of the prototypical combustor. As expected, the lowest NOx emissions were achieved with configurations having a lean primary combustion zone. Such configurations have proven to be capable of significantly reduced NOx emissions without increasing the amount of steam.
