ABSTRACT
The paper presents the complex energy analysis of technological systems of gas-steam power plants integrated with coal gasification. The basis of the performed energy analysis are the elaborated mathematical models describing the behaviour of main elements of the gas-steam power plants integrated with coal gasification, such as: gas generator, gas cooler with the gas desulphurisation system, gas turbine block (compressor, combustion chamber, and gas turbine), heat recovery steam generator and steam turbine cycle. The mathematical models of particular elements of power plant were the basis for computer programs for multivariant numerical simulation of energy effectiveness of power plants. The influence of: coal gasification technology, gasifying medium, gas fuel desulphurisation technology and gas turbine parameters on the efficiency of electric energy generation were taken into account.

W artykule jest przedstawiona kompleksowa analiza efektywności energetycznej elektrowni gazowo-parowych zintegrowanych ze zgazowaniem węgla. Podstawą wykonanej analizy są opracowane modele matematyczne podstawowych elementów elektrowni gazowo-parowej zintegrowanej ze zgazowaniem węgla, takich jak: generator gazu, chłodnica gazu z układem jego odsiarczania, bloku turbiny gazowej, kotła odzysknicowego oraz obiegu turbiny parowej. Jako wielkość charakteryzującą efektywność energetyczną elektrowni gazowo-parowych zintegrowanych ze zgazowaniem węgla wyznaczono sprawność wytwarzania energii elektrycznej, dla układów technologicznych z różnymi metodami zgazowania węgla, różnymi metodami odsiarczania gazu oraz różnymi parametrami turbin gazowych.
