公司：求购POWER PLANT MACHINE 国家：** 联系人：** 地址： 客人的求购信息如下， 请厂家和我MSN联系。 5 SELECTED PLANT DESCRIPTION 5.1 General The proposed power plant is designed for base load application and is intended for electricity production in parallel operation with the NTDC grid. The power plant consists of 8 engines in combined cycle mode with exhaust gases boilers in each engine and one steam turbine, without any extra burning of fuel, increasingly significantly the efficiency of the complex. As said previously, today there are only two reliable reciprocating engines suppliers of that size in the world market, which are Wartsila from Finland and MAN from Germany. Both had in their portfolios HFO engines, with remarkable experience. However, Wartsila has bigger experience with their engines, the 18V46 with 16.9 MW, because is a power plant worldwide leader with reciprocating engines. MAN had also a very good records with their engines, 18V48/60, with 18.5 MW. On table 5.1, can be seen a comparison of both configurations presented by the manufacturers. Table 5.1 – Comparison of Plant Machineries Alternatives from Wartsila and MAN Description Units Wartsila 18V46 MAN 18V48/60 Quantity of gensets 8 Capacity of each genset kW 16,934 18.428 Total capacity MW 147.424 Steam turbine kW 8,396 8,432 Total gross capacity MW 147.424 Auxiliaries kW 3,200 3890 Net Power Output kW 107,061 116,321 Heat rate of genset (site) kJ/kWh 8,079 8,146 Efficiency of genset 44.6% 44.2% Heat rate of Plant (site) kJ/kWh 7,663 7,730 Efficiency of genset 47% 46.6% As we can see above, Wartsila 18V46 shows a little better performance that connected to the bigger experience with that type of engine and plant, the consultants recommend the use of Wartsila engine18V46. 5.2 The Concept The proposed plant concept is of 148 MW gross power and net power of 146 MW, in combined cycle mode. The main fuel is RFO. The main components of the plant are 8 gensets from Wartsila of 18V46 type, 16.9 MW each (at site conditions) plus a steam turbine of 8.4 MW. As the auxiliary power consumption of the plant is estimated at 2.3 MWe, the overall net electrical output of the plant is 147.0 MWe. The power plant will be connected to NTDC's 132 kV grid. 5.3 Plant Performance Configuration The Stationary power plant is equipped with 8 engines of the Wärtsilä 18V46 type, as the prime mover.
