The thesis is devoted to the utilisation of expansion turbines in the thermal power stations and in the industry companies using gas pressure reduction for technology purposes. The theoretic part of this thesis deals with the technology equipment such as steam and gas turbines, generators and reduction stations. The special attention is given to the expansion turbines with regard to its dividing in two groups: for steam reduction and for gas reduction. The parctical part includes the preliminary and detailed calculation of the expansion turbin for parameters of reduction line for combustion turbines, the generator proposal and the possibility of power extraction. The economic part completes the thesis with the economic evaluation of investment efficiency.
