The 5th power unit was launched at the thermal power station of Darkhan city. Mongolia's third largest city will be provided with additional heat thanks to a new 35 MW turbine manufactured at the Kaluga Turbine Works.
Since 1966, 4 type ПТ-12 turbines from Kaluga with a total capacity of 48MW have been installed at the coal-fired CHPP plant. For more than half a century the installations have been operating properly. Taking into account the growing energy needs of the city, it was decided to install an additional turbine, increasing the capacity of the CHPP by 35MW.
Nikolay Shulenin, Chief Designer of KTW, spoke about the technical specifications of the new turbine unit and the works carried out to improve the turbogenerator complex for Darkhan CHPP:
"The ПТ-35/39-3,4/1,0 turbine belongs to the new generation of heating steam turbines. The steam inlet part of the machine was modernized with respect to the turbine prototype ПТ-25 in terms of increasing the throughput capacity to allow more steam to pass through in order to increase power."
Installation and commissioning of the turbo-generator unit was carried out under the supervision of KTW's chief engineers.
While the works were being carried out, a delegation from Mongolia visited the Kaluga Turbine Works. In the context of the visit, negotiations were held on the supply of additional spare parts for servicing Darkhan CHPP. Upon completion of the installation, the Executive Director of the CHPP M. Zhargalsaikhan sent KTW a letter of gratitude:
“Darkhan CHPP expresses gratitude to the specialists of OJSC KTW for conscientious and professional technical management of installation, start-up and set-up operations and successful commissioning of the type ПТ-35/39-3,4/1,0 turbine. We would like to express our special gratitude to the employees of OJSC KTW for the prompt production and shipment of the necessary turbine parts in order to complete the installation works. We hope to continue cooperating with your company in the future!"
On October 5, a special event dedicated to the official launch of the 5th power unit of the CHPP took place in Darkhan. Energy Minister of Mongolia Tserenpiliin Davaasuren voiced the desire to further modernize the Darkhan CHPP by replacing turbines delivered in the mid-60s with new turbines produced by KTW since they have already proven to be reliable.
Productive bilateral negotiations were held at the event, the possibility of replacing two exhausted turbines at CHPP with new condensing turbines manufactured in Kaluga or analogue of the installed type ПТ-35/39-3,4/1,0 turbine were discussed, which would greatly simplify maintenance and supply of spare parts to the CHPP.
