Analysis of the Operating Mode of the “SHIMAL-1”
Steam–Gas Plant Condenser
Abstract
The article emphasizes the importance of modern technological schemes of newly operated combined-cycle gas turbine (CCGT) plants in energy production in our country. By examining their cycle, thermal scheme, the operation of thermal equipment, and the normal operating modes of the equipment, the joint operation of a gas turbine unit (GTU) and a steam turbine unit (STU) in a combined configuration is analyzed. In order to optimize the performance indicators of a steam–gas plant under operating conditions, the characteristics of the condenser’s operating and service modes are evaluated. Considering that the efficiency of combined steam–gas plants depends on the individual efficiencies of the steam and gas cycles, the factors influencing each cycle’s efficiency are discussed. In particular, to assess the impact of condenser characteristics on the effectiveness of the STU, the operational characteristics of a box-type condenser based on experimental data are analyzed.
Additionally, it is highlighted that the use of profiled tubes in the heat-exchange equipment of these plants can enhance heat transfer, thereby improving their efficiency indicators.
