<p>A combination-cycle electric power plant has a gas turbine unit (2); a steam turbine unit (3); a steam circuit (17) extending through a number of heat exchange modules (15, 24, 30, 33, 34, 35, 37, 38, 40, 41, 42, 43, 44) arranged in line; and a post-firing, heat-recovery steam generator (16), which transfers the residual energy of the exhaust gases from the gas turbine unit (2) to the steam, and is equipped with a power-adjustable first burner (20) for heating the number of heat exchange modules (15, 24, 30, 33, 34, 35, 37, 38, 40, 41, 42, 43, 44), and with a power-adjustable second burner (21) arranged to only heat some of the heat exchange modules in the number of heat exchange modules (15, 24, 30, 33, 34, 35, 37, 38, 40, 41, 42, 43, 44).</p> |
