The invention discloses an efficient cleaning system for a boiler and a passive film of a water supply system. The efficient cleaning system comprises a medicine dispensation circulation circuit and an acid pickling circulation circuit. The medicine dispensation circulation circuit comprises a deaerator, a front-arranged pumping set and a water supply recirculation piping set which are connected sequentially through pipelines. The acid pickling circulation circuit comprises the deaerator, the front-arranged pumping set, a high-pressure water supply system, a main water supply operating platform, a coal economizer, a steam pocket, a downward piping set, a lower water cooled wall header, a downward piping set blow-off pipe, a main blow-off pipe, a unit blow-off groove and a deaerator water discharging pipeline. Waste pollutants discharged from blow-off pipes and waste pollutants discharged from the downward piping set blow-off pipe are discharged into the unit blow-off groove through the main blow-off pipe. The efficient cleaning system for the passive film of the boiler is capable of effectively removing the incrustant passive film in the boiler and the water supply system, and has the advantages of being convenient to operate and control, short in cleaning period, high in security coefficient of personnel and equipment, almost free of pollution to the environment and the like. The efficient cleaning system has a good practical value and application prospects.
