The utility model discloses a flue gas waste heat power generating system comprising an ammonia steam turbine, which is characterized by comprising an ammonia water-smoke heat exchanger, an ammonia steam turbine, a generator, an injection pump, a strong ammonia water storage tank, a dilute ammonia water storage tank and two ammonia water pressure boosting pumps. The ammonia water-smoke heat exchanger is arranged in a flue, ammonia water is subjected to heating, evaporation and gas and liquid separation in the heat exchanger, dilute ammonia water in the dilute ammonia water storage tank is delivered to the injection pump via a dilute ammonia water pressure boosting pump pipeline to condense and absorb ammonia from an exhaust pipe of the ammonia steam turbine, simultaneously, vacuum is formed in an ammonia steam turbine system, and the ammonia steam turbine converts kinetic energy and thermal energy of the ammonia into mechanical energy so as to drive the generator to generate power.
