«Comtec-Energoservice» will supply a steam turbine-generator installation ПТГУ-12000 for JSC «EUROCHEM– NORTHWEST» within the framework of the project «Production of Ammonia, Kingisepp. Power plant» for JSC «EuroChem-Northwest». 

«Comtec-Energoservice» shipped a steam box of check valves for PJSC «ENEL Russia»

Under a contract with PJSC «Enel Russia» «Comtec-Energoservice» shipped a steam box of check valves for turbine K-300-240 Konakovskaya GRES. 

Steam turbines

“Comtec-Energoservice” designs and builds steam turbines from 0.5 to 12 MW according to the specific customer requirements . Most of the offered design approaches have been proven to be effective, both in terms of improved efficiency and improved operational characteristics as well as unit cost reduction of a supplied kilowatt of electricity.

When we design a turbine, we consider all the details such as operation modes ;working hours duration; loading schedule, variation range of initial and final steam parameters, etc.

By now we manufactured and shipped nine condensing and backpressure type steam turbines from 1 to 5 MW.

Our experts can help you to design all the technical specifications for a generator turbine or drive turbine.

of Steam turbines

We have a big experience in reconstructions of steam turbines from 12MW to 500MW built by “LMZ”,”UTZ”,”HTGZ” etc., including turbines made by foreign companies. All reconstructions and modernizations ,are used to increase the capacity , reliability, efficiency and repairability.

Our largest reconstructions over the past few years:
• Reconstruction of PT-80-130 LMZ turbine at Rostovskaya TPP-2
• Reconstruction of PT-60-130 LMZ turbine at Kazanskaya TPP
• Reconstruction of K-200-130 LMZ turbine at Moldavskaya TPP
• Reconstruction of K-500-240 HTGZ turbine at Nazarovskaya TPP
• Reconstruction of T-120-130 LMZ turbine at Novo-Kemerovskaya TPP
• Reconstruction of R-50-130/13 LMZ turbine at Irkutskaya TPP-11
• Reconstruction of PT-25-90 UTZ turbine at Irkutskaya TPP-11
• Reconstruction of VK-50-90 LMZ turbine and thermal circuit at Svetlogorskaya TPP
• Reconstruction of AEG-12 Siemens at Barnaulskaya TPP-11

Modernization of steam turbine
parts and units

Modernization of steam distribution units

The reliability and efficiency – are the main requirements for steam distribution parts and units. Improving the reliability of these units is one of the main purposes in power engineering. That is why this activity is considered to be one of our priorities.

As a result of many years of theoretical, experimental and design work we have developed, formed and tested the design principles that provide guaranteed reliability and high efficiency of the valves. We have extensively used the experience of manufacturers, repair services, power plant operating personnel, as well as technical and patent literature.

"Comtec-Energoservice" currently, developed, patented and successfully implemented (more than 1000 implementations) such developments as:

• Modernization of control valves
• Modernization of check valves
• Installation of valve seal airtight
• Modernization of valve drive units
• Modernization of the cam-switchgear

Modernization of shaft seals for turbines from 50 to 800MW

“Comtec-Energoservice” offers modernized high-temperature and low-temperature shaft seals for turbines from 50 to 800MW. More than 10 years our shaft seals reliably works on such turbines as R-50, PT-60, PT-80, T-100, T-180, K-200,K-300-more than 120 turbines at Russian TPP’s and abroad. The solutions proposed by our designers became so successful that our shaft seals are now currently used on the new turbines of such plants as "Power Machines" and "UTZ".

The main advantages of our shaft seals are:

• High reliability (reducing the warp effect)
• Improved repairability
• Increased rigidity of the structure
