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

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.
