Method for controlling temperature of main steam behind high-temperature superheater of boiler

The invention relates to the technical field of temperature control, and discloses a method for controlling the temperature of the main steam behind the high-temperature superheater of a boiler. The method comprises the following steps that S1, a low-temperature superheater, a medium-temperature superheater and a high-temperature superheater are sequentially installed at fixed positions, and a proper master controller is selected as center equipment for regulating and controlling the whole steam temperature; S2, a first snakelike steam pipeline is additionally arranged between the low-temperature superheater and the medium-temperature superheater, and a second snakelike steam pipeline is additionally arranged between the medium-temperature superheater and the high-temperature superheater; and S3, a first temperature measuring probe, a second temperature measuring probe, a first electromagnetic valve and a second electromagnetic valve are arranged on the inner sides of the two ends of the first snakelike steam
