Ural Turbine Works (ROTEC Holding) has shipped the equipment for modernization of turbine Т-100/120-130-3 at Pavlodar CHPP-3 (AO PAVLODARENERGO). This is the third turbine T-100 being modernized at this power plant. The first one was put into operation in December 2014. A test run of the second turbine unit was performed in the end of 2015. It's planned to commission the third unit, recently shipped, in the third quarter of this year.
Modernization will allow not only for complete service life recovering of the equipment (turbine operating life — 220 ths. hours or about 40 years), but also for increasing electric power output by 20 MW per each turbine. This is achieved through the replacement of the overaged high and middle pressure cylinders and the wheel space components with new equipment optimized for 10% increase of the main steam rate, as well as due to utilization of the advanced blade system. In general, the efficiency factor of the turbine will increase by 1.2-1.4%. After commissioning, the turbines will be provided with new marking — Т-120/130-130 ПР2.
