Preliminary quotation is 45 millions Chinese Yuan, just for indicative, would be adjusted to negotiation, payment arrangement, and demands.

Profile

The preparation of the power plant started in 1995. The first phase of the project is to install a 51.4MW combined cycle turbine-generator unit, of which gas turbine capacity is 36.4MV, and steam turbine capacity 15MV, with a total investment of 20 million US dollars. The gas turbine single cycle generator unit was successfully commissioned in December 1996, and the steam turbine generator unit was put into operation in July 1997. The Units own the advantages of fast start-up and high thermal efficiency, which makes it possible to reach the full load from stand-by just a little more than 10 minutes. The Plant has been generating 1269.08422MKW (of which 23.2749MKW was generated after heavy oil renovation), making contribute to releasing the power shortage of Zhejiang Province.

Equipment condition

Up to now, the equipment has been running well, which consists of the following:

The gas turbine, PG6471B, was made by China Nanqi Group, of which the core parts were imported from GE Company. Formerly, 0# diesel was used as the fuel and the unit ran smoothly for 10 years without major equipment failures. Due to the rapid rising of international oil price, the cost couldn’t maintain the ordinary generation. So the plant spent 1 million US dollars on the heavy-oil renovation in 2005, which was conducted by Shanghai Power Generating Equipment Company. After the renovation, the generation cost was rapidly decreased, which laid sound foundation for the further development of the Plant. Up to now, the total number of start-up has reached 2057, and light oil has been used for 29845.5 hours and heavy oil 422.6 hours. Strictly conforming to the GE standards, the plant has conducted three routine overhauls and medium maintenance, focusing on the periodical check and maintenance of the unit. During the overhauls, some technical innovations were conducted to some parts, which improved the economical efficiency and liability of the gas turbine.

The main spare parts of the gas turbine are complete.

The spare parts supplied together with the unit and some expendable spare parts are also available.

The steam turbine, N15-3.43, has operated for 26067.29 hours since it was put into operation on 10th June, 1997. During this ten-year operation, the unit was examined, repaired and renovated four times, of which the routine maintenance was conducted in the years of 1998, 2000 and 2004. In June 2002, three-dimensional renovation was applied to the unit, which replaced all interior parts except speed control system, ratchet system and cylinder. After the renovation, the steam consumption rate has been no more than 4.138KG/KW.H

As for boiler, Q387/498-55-3.82/445, annual inspection and repair are applied only to the water pump, fan, expansion joint and boiler body due to the simple construction of the heat recovery system. In 2002, as a part of the three dimensional renovation of the gas turbine, two new shields were installed at economizer and the shield of the super-heater was replaced.

The electric part mainly consists of two outgoing lines connected through 110kV gapping switch. The two lines both adapt computer protection system (RCS-941A) made by Nanrui Relay Protection Company. The 110kV CB is of SW4-110-3II oil-minimum. The main transformer is of SF8-63000/110 no load regulating. The tree auxiliary transformers of the 10kV section are of S7-1250/10、S7-800/10、S7-1250/10 no-load regulating respectively. The 1# generator is of QFR-36-2 with its 10kV ZN12-10 CB, and the 2# generator is of QF-15-2 with its 10kV ZN28A-10 CB. All these main devices are operating well.

The specialized water for oil chemistry is from river and is mixed with coagulant. The water is coagulated and filtered by water processor. The make-up water for production is treated through demineralization. The rate of discharge of the both devices is 19.6t/h, which form a parallel linked system. There is a middle scale oil chemistry lab and a imported oil analysis spectrometer, which can analyze micronutrient levels and condenser point and flash point to ensure the oil quality.

Analysis of availability

Due to the fact that the gas turbine, steam turbine and boiler have all operated for less than 30000 hours and been carefully maintained, they run soundly and still have a long time to reach their service life limits. Additionally, the following reasons contribute to their higher values:

　/P>

The gas turbine consistently uses 0# diesel oil, not heavy oil, so the core parts and important auxiliary parts suffer very little corrosion damage. And all the spare parts are complete.

A three-dimension renovation was conducted on the gas turbine in 2002, and almost all the interior parts were replaced by new ones and so its efficiency was increased.

The economizer and some super-heaters of the boiler were also replaced by new ones in 2002 to further raise its thermal efficiency.

　�The existing equipment is flexible to be fed with diesel oil or heavy oil, or even natural gas after small modification.

The advantages of gas turbine power plant are: short construction period, less land resources, less fixed investment per kilowatts, and fast start-up and stop and so on. It is also clean and environmentally friendly.

The construction period, from the date of the arrival of the equipment to the operation date after commissioning, is about half a year. Taking into the consideration of building foundation and workshop, the whole construction is normally less than one year.

The gas turbine power plant also has flexibility to choose its site. If natural gas is used as the fuel, the plant even can be built in urban; if oil is used, then the plant normally is built in the suburbs A land of about 33,000km2 is enough for a set of combined cycle turbine generator. It will be much better if there are some rivers or lakes around to supply water to the unit though the required water quantity is not big. Also, natural gas pipes should be conveniently connected to the plant.

Natural gas is the best choice for the gas turbine for its cleanness and low cost. 1m3 natural gas can produce 4kW.h electricity, and the price of natural gas is lower than that of oil now.

If our equipment is used to build a 50000kW Power plant, the fixed investment per kW is about 280 dollars, which is much less than that of a power plant using new equipment. It is only about one third of that of a small scale coal-burring station or hydraulic plant. Besides of its short construction period, this is an obvious advantage to build a power plant in areas rich in natural gas.

Our gas turbine is started up by diesel, so it also can be used as an independent power supply where other electric sources are not available.
