Note:
L’articolo, dopo un’ introduzione relativa al mondo “General Electric”, presenta come GE Oil & Gas intenda affrontare il mercato della Small Power Generation (5 - 10 MW) con le proprie Turbine a Gas GE5-1 e GE10-1.
Saranno descritte le caratteristiche principali delle due turbine a gas, particolarmente adatte agli impianti di cogenerazione industriale, e sarà fatto cenno alle attività di sviluppo tecnologico di queste macchine e alla nuova strategia di GE Oil & Gas per il mercato della small power generation.
The paper, after a brief overview on “General Electric” family and on “GE Energy” business, will illustrate how GE Oil & Gas (a GE Energy business) intends to approach the Small Power Generation segment (5 - 10 MW).
In particular the article will present in detail the technical features of the new generation of 6 and 11 MW class single-shaft engines, recently developed by GE Oil & Gas Nuovo Pignone: the GE5-1 and GE10-1 Gas Turbines.
Based on the extensive experience gained on the field of proven PGT5 and PGT10 models, the GE5-1 and GE10-1 gas turbines have been specifically designed by taking into consideration the small power generation requirements and are at the top of their categories in terms of efficiency and exhaust energy.
In particular, both models are equipped with a new axial compressor, which has allowed us to improve the performance and reduce the stages from 17 to 11 by utilizing the 3D profiles.
Both GE5-1 and GE10-1 gas turbines are equipped with last generation combustion systems, that allow maintaining the NOx emissions level under 25ppm (the GE5-1 standard unit is DLN configured)
On this subject the article will illustrate also the GE Oil & Gas Go-to-Market strategy and the steps of the improvement process of the emission impact and performances.
