Abstract

Perspective directions of the development ofenergy is connected with gas turbine and combined cycle thermal power plants. Combined cycle plants practically have disadvantages, rather it is necessary to talk about certain limitations and demands of equipment and fuel. Installations, can operate at the use of natural gas in a gas turbine installations, heavy fuel oil, crude oil, incidental products of oilprocessing, synthetic gas got at gasification of coal. Kazakhstan has all the necessary conditions for the construction of combined cycle thermal power plants, because production of natural gas in the Western and Southern Kazakhstan
is widely developed in the country. The operating costs of a powerful modern combined cycle plantstwice lower than dust-coal power plants. Terms of construction combined cycle plants is much shorter than powerful thermal power plants of other types. Therefore in Kazakhstan it is necessary widely propagandize and introduce the construction of combined cycle plants in the new energy politics of Kazakhstan. Currently, an important task is identification of advantages and disadvantages of the different
schemes and research of the indicators of thermal economy of combined cycle plants with thermal power plants.
