Heat force of the clockwork with a gas turbine and a steam generator for a more pressure - steam turbine

摘要

For the development of a high pressure steam, at least two overheating stages (10-12) are used in series, fitted with an injection cooling (26,27). For an intermediate pressure steam, at least two intermediate pressure stages (13,14) are used with an injection cooler (28). The end stages (12,14) of the high and intermediate pressure systems are located at the same section of the boiler (9), with their pipes aligned alternately among each other in a comb-shaped layout. The intermediate pressure steam stage (13) is between or after the first two high pressure steam stages (10,11). The first burner (6), using the exhaust of the gas turbine, is at the boiler (9) near the end stages (12,14) of the high and intermediate pressure systems. A second burner (25) is at the boiler (9) in front of the high pressure steamer (21). The first burner (6) is controlled according to the steam temp. at the outlet of the first intermediate pressure stage (13), and the second burner (25) is controlled according to the high pressure loading.
