Power machines completed the shipment of equipment manufactured for the Chita TPP-1 of JSC «TGC-14» modernization

Power machines completed the production and shipped the last batch of equipment made for the modernization of Chita TPP-1 Turbine No.1 A high-pressure cylinder (HPC) of a steam turbine weighing more than 40 tons is among the largest units sent to the customer.

The contract for the modernization of the PT-60-90/13 heat turbine of Chita TPP-1 provides for the production of equipment set for the modernization of the turbine, including such large units as the HPC, the high pressure rotor and the lock valve box, as well as units for modernization under conditions of the medium and low pressure cylinder station (MLPC). In addition, the Power machines experts will provide installation supervision services.

Production of the equipment is conducted at the Leningradsky Metallichesky Zavod which is a part of PJSC «Power machines».

Leningradsky Metallichesky Zavod has developed a wide range of technical solutions which allow them to perform many technological operations in the shortest time possible and with minimal costs. These include subassembly equipment modernization with an increase of technical and economical parameters to the present-day level as well as complete replacement of this type of turbine.

As a result of the works, the steam turbine with a capacity of 60 MW will be converted into a «AP» (anti-pressure) type. The new wheel space part of LPC developed by the designers of the company allows it to exclude the condenser from the work and to avoid heat loss, directing all the steam to the heating selection during the modernization.

Implementation of the project will increase the reliability of heat and electricity supply of the TPP, extend the service life of the equipment, increase the efficiency of Chita TPP-1 when the turbine is operated in the back pressure mode.

The beginning of works on installation of delivered equipment at the Chita TPP-1 is planned for the third quarter of this year.
