The moderate repairs of power unit No. 9 have been performed at the DTEK Prydniprovska TPP. The power unit will steadily supply over 100 MW of electricity to the national energy system during a heating season.
During two months, specialists inspected shutoff and control valves of the pumps at the turbine and boiler houses. They also repaired and aligned the electric filter and restored cleaner elements of precipitating electrodes to achieve better scrubbing of flue gases and reduce the emission of dust into the air. A steam generating unit was also repaired to prevent the disruption of a process and ensure its stable operation during a cold season. 11 tonnes of the boiler’s screen system were replaced. The total length of welded seams reached 1.5 km. Their quality and reliability were controlled by the chemical lab of Prydniprovska TPP. The lab specialists examined over 12 thousand of seams using visual and ultrasound control methods.
‘DTEK is a responsible and reliable company. We are constantly inspecting the condition of our equipment to ensure its uninterrupted operation during any season of the year. We have just completed the scheduled moderate repairs to power unit No. 9. A lot of effort was taken to upgrade it. We do this to ensure that the residents of Dnipro receive quality heating and energy supply services during a winter,’ commented Anatolii Borychevskyi, Director of DTEK Prydniprovska TPP.
Energy workers expect that the technical measures implemented within the scope of the repairs will reduce the breakdown rate by 1.79%, increase the capacity of the power unit by 5 MW, and reduce the consumption of equivalent fuel by 1.8 gr/kWh. This will improve the cost of electricity generation and make it more competitive.
In the past 10 years, DTEK ENERGY has invested over UAH 28 billion in the upgrade and repairs of thermal power plants. Out of 23 power units that have been retrofitted in Ukraine, 21 power units are operated by DTEK ENERGY’s TPPs and have electrostatic precipitators that have been either constructed or renovated.
As a result, in the past eight years, the TPPs privatized by DTEK since 2012 have been able to reduce the emission of pollutants by 58%. Dust emissions have been reduced by 67% in aggregate by all TPPs.
The reduction of emissions by TPPs is a result of changes in the energy mix achieved by reducing the share of TPPS and increasing the share of RES, as well as systematic investments made by the company in the construction and retrofitting of electrostatic precipitators.
