At the "Electrosila" being the branch of the OJSC "Power Machines", for the first time in Russia, prototype model of turbogenerator of the type of Т3ФП-220-2У3 having capacity of 225 MW with full air cooling has been manufactured and successfully tested.
The turbogenerator manufactured for the constructed power unit of Krasnoyarsk TPP-3 (The OJSC "Yeniseyskaya TGK (TGK-13)"), has been the continuation of the series of ТЗФ generators with air cooling, having capacity of 63-160 MW developed previously at the branch. The turbogenerators with air cooling feature high reliability; they are simple in service, expenses on operation thereof are insignificant; therefore, these machines are the most effective for use in the structure of gas-turbine and ССPP installations.
Creation of a turbogenerator with full air cooling, having capacity of 225 MW became possible due to application of new design solutions and use of materials with improved properties. The turbogenerator, for the first time ever, uses a new patented system of cooling of the winding and the core of the stator.
Now the turbogenerator shipped to the customer is at the site of the station. The works for installation of the electrical equipment will start by the first half-year of 2009.
Krasnoyarskaya TPP-3 – a branch of the OJSC "Yeniseyskaya TGK (TGK-13)". The power plant provides heat supply of the industrial enterprises and housing and communal sector of left-bank districts of the city of Krasnoyarsk – micro-districts of "Severny", "Vzlyotka", a new building-up of "Zelyonaya Rostcha". The construction of the Krasnoyarskaya TPP-3 was started in 1981. During the 1990s the construction was suspended, and in 2007 it was recommenced in compliance with the investment programme of the OJSC "Yeniseyskaya TGK (TGK-13)". At present, there are four water-heating and 3 steam boilers of the total capacity of 443 Gcal/h in operation.
