Abstract
This article is devoted to the retrofitting of one of the 300-MW power units at the Kirishi district power station carried out using the combined-cycle technology in order to increase the power unit capacity and make it more efficient. The main and auxiliary equipment of the retrofitted power unit are described. The problems revealed and solved in the course of adjustment works are mentioned. Problems concerned with organizing the startup modes of combined-cycle power units fitted with three-loop heat-recovery boilers and a double-bypass startup circuit arrangement are touched. The design and actually achieved technical and economic indicators of the main equipment and the power unit as a whole are presented. A tangible economic effect is noted from a comparison of the key indicators before and after the retrofitting. It is shown that the retrofitted power unit has good environmental indicators and a very high level of automation.
