Influence of structure of heat recovery steam generator and of gas turbogenerator power repowering a 370 MW unit on the power plant operating in cogeneration cycle

W artykule zaprezentowano rezultaty termodynamicznych obliczeń doboru struktury kotła odzyskowego i mocy turbozespołu gazowego do bloku o mocy 370 MW zmodernizowanego do dwupaliwowego układu gazowo-parowego. Obliczenia przeprowadzono dla pracy skojarzonej bloku.

The paper presents results of technical calculations involving the selection of a structure of heat recovery steam generator and of gas turbogenerator power applied for adaptation of a coal-fired power unit with the rated capacity of 370 MW to dual-fuel steam-gas system. Calculations were conducted for a unit operating under cogeneration cycle.
