OJSC Kaluga Turbine Works (OJSC KTZ), a part of Power Machines Group, made the first-ever 64 MW turbine for Pervomaiskaya CHP-14 in St. Petersburg (a part of OJSC TGC-1).
Power Machines signed a contract for equipment procurement for two 180 MW CCGT units in 2007. Pursuant to the contract the company was to supply two steam turbines, 64 MW each, two turbo-generators, four packaged gas-turbine units and auxiliary equipment. Furthermore, the contract stipulated installation supervision and technical management of start-up operations.
Machine Т-50/64-7,4/0,12 manufactured by KTZ is an cogeneration turbine with heating steam extraction and steam bleeding. It is designed to serve as a driver for turbo-generator mounted on a single base plate with turbine and should operate as a part of CCGT Unit-180. The main distinctive feature of the turbine is its throttle moisturing device which allows to feed both high and low pressure steam to the condenser aside from turbine. This device is a know-how of KTZ engineers. Turbine Т-50/64 opened a new production line in the enterprise. This new solution is based on extensive engineering experience gained by the enterprise for more than 60 years of its existence. All turbine assemblies were manufactured in KTZ shops. A new test stand was built to test the turbine.
“Development of a new high-capacity production line of turbines is a milestone in our enterprise growth,” says Mr. Yuri Maksimov, Director General of OJSC KTZ. “It made designers, engineers, and workers to innovate and use fresh approaches. And the enterprise has managed to cope with this challenge.”
