Kaluga Turbine Works OJSC (KTZ OJSC), member of Power Machines Group, has manufactured a T-50/70 steam turbine having a capacity of 70 MW for Chelyabinskaya CHP-3 (belonging to Fortum OJSC).
In September 2007, Power Machines signed contracts for delivery of power-generating equipment to implement investment projects by TGK-10 OJSC (presently called Fortum OJSC). The total value of the concluded agreements is over 4 billion roubles. According to the contract terms Power Machines shall supply equipment for the following three power plants: Tyumenskaya CHP-1, Chelyabinskaya CHP-3 and Tobolskaya CHP.
For a 220 MW PGU-220 steam-generating installation being built at Chelyabinskaya CHP-3 the company shall provide a GTE-160 gas turbine, a Т50/70 steam turbine and also two 65 MW and 160 MW turbogenerators.With this T-50/70 turbine KTZ OJSC has continued to launch production of turbines of a new capacity range. The first-ever machine having a capacity above 50 MW was made in August this year for Pervomaiskaya CHP-14 in St. Petersburg. Most of the solutions implemented in the first machine have been used to develop the Chelyabinsk turbine. But design parameters and steam consumption requirements of Т-50/70 turbine have been different from those of the turbine for Pervomaiskaya CHP, and the machine’s capacity has been increased up to 70 MW. The turbine has been tested at a factory test bench developed and built specifically for this new capacity range.
