Introduction to Bangladesh Chandpur GE9E Combined Cycle Power Plant Project
Issued Time :2015-02-05 08:56:46

A set of gas turbine generator unit (provided by GE French Company 9E12MW) is equipped in the power plant. The unit, including rotor, axial flow compressor, impulse turbine, exhaust section and burner, adopts heavy monolithic structure and outdoor layout. Apart from that, a set of HRSG which uses America Atlas compressor is installed in the power plant. At high pressure, the temperature and evaporation capacity of the HRSG are 540 and 110.5 t/h respectively, while at low pressure the parameters change to 270 and 13t/h.

The natural circulation gas turbine HRSG, with dual-pressure deaeration, horizontal arrangement and without afterburning, is used for the gas turbine which adopts natural gas and other clean fuels as design fuel. 1 set of turbine generator (provided by Siemens Sweden SST-900-c) is also arranged, the rated speed of the single-shaft and condensing type steam turbine is 3000r/min.

This project uses dual-fuel, natural gas or light diesel oil respectively. The design is on the basis that either fuel can meet the requirements of the combined cycle operation. In this stage, natural gas is used as the primary fuel and light diesel oil serves as backup fuel. The pressure of gas, supplied by gas companies is 425psig(2.93MPa) and the temperature is not less than 25 . Power plant basic operation mode is combined cycle with rated load, when burning natural gas, the unit net output is approximately 209MW.

O&M Power is responsible for providing comprehensive technical services to EPC, which include training, unit commissioning, operation and technical service during warranty period.
