Frame 6FA (PG6111FA) gas turbines with a capacity of 80 MW each were successfully tested at the General Electric plant in Belfort (France). They were designed for the Flint investment project of IES Holding that involves extension of Novokuibyshevsk CHPP-1 by construction of a CCGT on parallel disposal lines.  Frame 6FA state-of-the-art high-performance gas turbines need much less fuel compared to other mid-level power units in the basic mode of operation and produce high-temperature exhaust gases which makes them good for binary CCGT applications. In terms of these parameters, Frame 6FA turbines have no analogues in Russia.
Extension of Novokuibyshevsk CHPP involves installation of a CCGT plant with a total capacity amounting to 240 MW. The plant will consist of three GE gas turbines and three IEG recovery boilers. The purpose of the project is enhancement of technical and economical parameters of the station, increasing its competitiveness on the wholesale and retail markets by way of reducing the cost of heat and electrical energy production, growth of energetic and economical effectiveness. The turbines were tested at full speed no load to check functioning of mechanisms, aero- and thermodynamic characteristics, vibration of the rotor. The standard procedure is to mount the turbine to some special test bench equipped with displacement, seismic vibrations and other sensors. The turbine is connected to startup, fuel supply, exhaust systems and wires. After startup the turbine is set to 14% of its nominal speed, then the speed is increased to 84% of the nominal value and for 1.5 hours it is supposed to operate at full speed while all the characteristics are checked. Tests finished, the results are sent to the Department of Engineering of GE. If the results are satisfactory, the turbine is painted and sent to the customer. |
