Abstract (en)
The present invention discloses a bypass control method, comprising: during the starting period of a generating unit provided with a bypass system, the boiler (1) is firstly started; the bypass system comprises a first-side bypass valve group (6,7) and a second-side bypass valve group (8,9)–¡closing the second-side bypass valve group (8,9) and at the same time widely opening the first-side bypass valve group (6,7), so that the steam through a outlet header (5) is discharged only from the first-side bypass valve group (6,7); after maintaining the first-side bypass valve group (6,7) open for a required time period, closing the first-side bypass valve group (6,7) and at the same time opening the second-side bypass valve group (8,9), so that the steam from the header (5) is discharged only from the second-side bypass valve group (8,9); after maintaining the second-side bypass valve group (8,9) open for a required time period, restoring the normal control and being prepared for impulse starting of a turbine (10). The erosion rate of the solid particles is reduced and the safety of the generating unit is improved by controlling the bypass system.
