The utility model relates to a steam Rankine-low-boiling-point working medium Rankine combined-cycle power generating device. The steam Rankine-low-boiling-point working medium Rankine combined-cycle power generating device has the advantages that a steam condenser for steam Rankine cycle is adopted as an evaporator for low-boiling-point working medium (such as ammonia steam) Rankine cycle, the characteristic that a low-boiling-point working medium Rankine cycle system has higher efficiency for utilizing medium-low-temperature heat sources is utilized, a great amount of vaporization latent heat released by steam condensation is used for low-boiling-point working medium Rankine cycle high-efficiency power generation, and the vaporization latent heat of the steam of the steam Rankine cycle is only used for generating power, so that more than 50kwh of electricity in every ton of steam is additionally recovered, simultaneously the safety difficulty of recovering waste heat of flue gas of low-boiling-point working
