The invention aims to provide a boiler fuel oil temperature control method. The method is characterized by comprising the following steps: determining a fuel oil temperature range and a target value SP; adopting two fuel oil temperature monitoring sensors, and obtaining boiler fuel oil temperature values T1 (t) and T2 (t) at the moment t; averaging the fuel oil temperature value T1 (t) and the fuel oil temperature value T2 (t) at the moment t to obtain a fuel oil temperature average value TV (t); obtaining the rotating speed R (t) of a turboset at the moment t, and converting the rotating speed R (t) into a correction value Q (t) through linear processing; subtracting the fuel temperature average value TV (t) at the t moment and the target value SP, and then taking an absolute value to obtain a deviation value E (t); converting the deviation value E (t) into a proportionality coefficient CP (t) and a differential coefficient CD (t) through linear processing; and calculating and outputting the opening degree K
