6. Quotation of the one set of combined cycle QD128:
The efficiency of QD128 combined cycle power plant as I have sent you the proposal and specficication is about 42% (27% for singel cycle, 15% for heat recovery system) and the parasisitic power consumption is 450kw. the heat recovery power capacity is around 4.5mw under ISO condition, and natural gas consumption is 4800-5300 Cubic meter per hour.
The quotation of the combined cycle power is about 10 million USD per unit, FOB China port, and of course it will change to technical and financing conditions.
You are welcome to inspect our power plant projects in China by using our QD128 gas turbine generator which can use both gas and diesel oil as fuel.
7. Performance credit
2 QD128 gas turbine projects have been build including Henan Wenliu Power Plant (cogeneration of heat and power), Helongjiang Daqing Weiya Power Plant (cogeneration of heat and power). After 10,000 hours continuous test run, the reliability and each technical targets have reached the standard of internationally mature units. In 2008, one unit was sold to Ganshu Akeshai and right now it is under construction (cogeneration of heat and power). In 2009, one unit was sold to Shanxi Luan Group,will generate in 2011.
3 sets of FR9E gas turbine simple cycle power generators were installed and commissioned in Pakistan Uqi(UCH) in March 1997. In 2010, 3 sets of PG9171E gas turbine combined cycle power generators were installed and commissioned in Pakistan.
