Embodiment 1
[0025] Such as figure 1 As shown, the gas-steam combined cycle generator set includes a steam turbine (HP+IP+LP), a gas turbine (GT+compressor+GEN) and an SSS clutch. The steam turbine is coupled to the gas turbine through the SSS clutch. The steam turbine includes a high-pressure cylinder and a medium-pressure cylinder and low pressure cylinders.
[0026] Such as figure 2 As shown, the method provided by the invention specifically includes the following steps:
[0027] The first step, the gas turbine starts the modified cleaning program. Under the drag of SFC, the speed of the gas turbine is stable at about 700 rpm (between 600 rpm and 900 rpm).
[0028] The second step, the steam comes from the adjacent machine, the medium-pressure cylinder rushes to turn the steam turbine to warm up (the high-pressure cylinder can enter steam in the forward or reverse direction), and the steam turbine speed is brought to about 700 rpm (600 rpm-900 rpm) ), synchronized with the speed of ...
