As concerns about global environmental problems grow, electric power plants that utilize high efficiency gas-turbine generators are being actively sought after.
Accordingly, at SaskPower's Queen Elizabeth Power Station in Canada, Hitachi, Ltd.
has implemented a re-powering system that combines Hitachi's H-25 gas-turbine generators with the plant's existing steam-turbine generators.
This re-powering system consists of H-25 generators combined with OTSG (once-through steam generator: also known as once-through boiler).
The H-25 gas-turbine generator incorporates a low-NOx emission combustor that meets the demand for low environmental impact.
The combustor is based on low-NOx emission technology that Hitachi has accumulated during the development of low-NOx emission combustors for large-scale gas turbines.
And it was shown during the commissioning that the low-NOx emission H-25 gas-turbine generators installed at the Queen Elizabeth Power Station produce NOx emission at the level of 25 ppm (at 15% O2).
In addition, the performance of the turbines was demonstrated to be satisfactory; that is, trouble-free operation down to -30
