System approach to the energy analysis of an integrated Oxy-Fuel Combustion (OFC) power plant, basing on “input-output analysis”, has been proposed. The state of the art concerning OFC power plants is presented as an introduction to the OFC technology. The full analysis has been presented together with an example concerning the mathematical “input-output” simulation model of energy and material balance of an OFC power unit. An example of applying the simulation model of a concrete OFC power unit has been provided. This model has been used to evaluate the system effects due to process changes. The influence of the purity of oxygen on the system effects has been presented. As a further possibility of applying the input-output analysis a mathematical model is anticipated concerning the choice of the optimal structure of an integrated OFC power unit with the application of Lagrange’s decomposition method.

Zaproponowano systemowe podejście do analizy energetycznej zintegrowanego układu elektrowni ze spalaniem tlenowym, przy wykorzystaniu analizy typu „input-output”. Przegląd literaturowy dla technologii spalania w atmosferze wzbogaconej tlenem i recyrkulowanego CO2 został przedstawiony jako wprowadzenie. Przedstawiona została analiza systemowa z wykorzystaniem modelu matematycznego typu „input-output” wraz z przykładem symulacyjnym analizowanego zintegrowanego układu spalania tlenowego. Model ten został wykorzystany do pokazania wpływu zmiany procesowej (zmiana czystości tlenu) na sprawność energetyczną oraz sprawność skumulowaną. Pokazano również możliwość dalszego wykorzystania analizy typu „input-output” do rozwiązania zadania optymalizacyjnego z zastosowaniem dekompozycji Lagrange’a.
