Optymalizacja parametrów czȩści parowej ukladu gazowo-parowego ze spalaniem tlenowym i instalacja wychwytu CO₂

This paper presents a gas turbine combined cycle unit with oxy-combustion. Oxy-combustion is one of the currently developed carbon capture and storage technologies (CCS). Firstly a gas turbine part of the unit is shown and the operating parameters are selected. The focus was on the impact of the compression ratio on the unit's efficiency. In the following section the steam parts in 3 units with different heat recovery steam generator (HRSG) construction were optimized. The single-pressure HRSG (1P), double-pressure HRSG with reheating (2PR), and triple-pressure HRSG with reheating (3PR). Optimization was performed by the means of genetic algorithm presented in this paper. The optimization results and achieved characteristic parameters of analyzed units are presented and compared.
