description	The invention discloses a method for suppressing a high exhaust temperature of a high-pressure cylinder in an FCB process. The method is applicable to the case that a steam turbine is under an intermediate-pressure cylinder start manner after FCB action, and comprises the following steps: acquiring the rotational speed of the steam turbine and the opening degree of a medium-pressure control valveof the steam turbine in real time; when the rotational speed of the steam turbine is less than a rated rotational speed, and the opening degree of the medium-pressure control valve is greater than a set opening degree value, controlling at least one high-pressure control valve to be opened at a predetermined speed and controlling a vent valve of the high-pressure cylinder to be opened, and reducing the opening degree of the medium-pressure control valve; detecting the rotational speed of the steam turbine, and the opening degrees of the high-pressure control valve and the medium-pressure control valve in real time; an
