Specialists from the United Engine Corporation (ODK, part of Rostec) will carry out a major overhaul and modernization of the NK-37 gas turbine engine at the Lida TPP in Belarus by early 2027. The work will involve updating key components, including elements of the low-emission combustion chamber.
The 43 MW power plant provides heat and electricity to the Lida district. The GTE-25/NK gas turbine unit, based on the NK-37, was commissioned in 2008. In 2011, the engine was equipped with a low-emission combustion chamber and an automated fuel supply control system. The modernized NK-37 successfully passed trial operation and continued to operate as part of the TPP.
The engine's operating time has reached its overhaul life of 25,000 hours. As part of the service maintenance, ODK-Kuznetsov specialists have begun a planned major overhaul and modernization. They will replace combustion chamber parts responsible for environmental performance, refine the support section, replace casings and bearings with more modern and reinforced ones, and install new sensors to monitor the condition during operation. The work will be completed in early 2027.
The 25 MW NK-37 engine was developed and manufactured at the Samara enterprise ODK-Kuznetsov. It combines high efficiency, reliability, and low operating costs. The total operating time of NK-37 engines in Russia and abroad has exceeded 230,000 hours.
A new line of power equipment is being created based on the NK-37 – rapidly deployable gas turbine power plants with capacities of 25 MW and 32 MW. Thanks to their high specific power and compact dimensions, modular GTPS can be deployed in the shortest possible time in energy-deficient areas.
