Development of NIIGATA new gas turbine pump drive unit ’CNT-4002MN’
Niigata Power Systems Co., Ltd. (NPS) has developed CNT-4002MN gas turbine unit for pump drive of output 4000 PS, and launched in 2010. This unit was made an output of 4000 PS by making two of two shaft gas turbines of output 2000 PS to one output shaft through the reduction gears. As two shaft gas turbine system for the pump drive, it is an output of a maximum level in Japan domestic market. In this paper, the feature of the specification of the gas turbine unit for this pump drive, the running performance, the start control, and other characteristics are described. The main engine of the pump drive unit is NGT2BM gas turbine, and it is consist by gas generator turbine which is installed two stage centrifugal compressor and two stage axial flow turbine and power turbines which is installed one stage axial-flow turbine. The rotational speed of the output shaft can be changeable in 700-1000min-1, and apply the waste water pump to various usages for another and a mechanical drive. For the load change while running, the full digital controller device is doing the fuel control and to stabilize the rotational speed of the output shaft of two set of two shaft gas turbines. Additionally, the prolonged running of one minute until the emergency power supply can be secured even when the black-out while running is possible. Moreover, the feature such as being possible to drive of the re-ignition while stopping and rapid starting is possessed. In recent years, the urbanization of the river surrounding area is advanced, and the importance of measures against flood in these regions increases in Japan. It is expected that this unit which has the above features can make the best use of features of the gas turbines such as light and small, large scaled power, low NOx, low noises and the low vibrations, and contribute to the flood control measures in the region as a pump facilities in the urban area where the installation requirement is severe.
