Krasnoyarsk CHPP-1 will put into operation 550 tons of new steam pipelines

The project involves a comprehensive environmental modernization and expansion of the Krasnoyarsk CHPP-1, as well as an increase in the capacity of the Krasnoyarsk CHPP-3.

As part of the environmental modernization of Krasnoyarsk CHPP-1, two boilers are planned to be updated at the station – No. 15 and No. 16. It is through these heat-resistant pipes that steam from boilers is supplied to turbines to warm up the coolant. The steam temperature is +550 °C with an operating pressure of up to 140 kgf/cm2. The wall thickness of the new steam pipelines will be increased, and after the implementation of the project, the temperature of the superheated steam will be 10 degrees higher than the previous indicators and will amount to +560 °C.

By the end of October, SGK power engineers will complete the installation of steam pipelines, pipes will be checked for strength and density, a thermal insulation layer will be applied and put into operation. The increased reliability of the equipment will ensure an uninterrupted supply of heat and electricity to consumers.

It should be noted that CHP-1 regularly updates the steam pipelines of boilers and turbines. For example, in 2021, the energy industry replaced 600 tons, and in 2023 – another 550 tons.

Also, as part of the comprehensive environmental modernization at Krasnoyarsk CHPP-1, two turbine units will be updated, 15 electrofilters with 99% particulate purification efficiency will be built. As a result of the implementation of the measures, the efficiency of the existing equipment will increase, and the emissions of CHP-1 will decrease by 20%.
