Abstract

The invention provides a binary Rankine cycle waste heat generating method, a binary Rankine cycle waste heat generating system and a generator. The binary Rankine cycle waste heat generating system comprises a dual evaporation pressure waste heat boiler, a high pressure steam heat recovering system and a low pressure steam heat recovering system, wherein the high pressure steam heat recovering system is used for recycling high pressure steam waste heat; the low pressure steam heat recovering system is used for recycling low pressure steam waste heat; the high pressure steam heat recovering system is a Rankine cycle system of water; and the low pressure steam heat recovering system is a Rankine cycle system containing water and an organic working medium. According to the binary Rankine cycle waste heat generating method, the binary Rankine cycle waste heat generating system and the generator, the dual evaporation pressure waste heat boiler is adopted; the high pressure steam heat recovering system is used for recovering high pressure steam, and the low pressure steam heat recovering system is used for recovering low pressure steam, so that stepped recycling of steam waste heat is realized and is effectively utilized; and compared with a single evaporation pressure waste heat boiler, the dual evaporation pressure waste heat boiler has the advantages that main steam parameters entering a steam turbine can be effectively improved and the generating efficiency of the steam turbine is improved.

Description

technical field [0001] The invention relates to the technical field of steam waste heat recovery and utilization, in particular to a duplex Rankine cycle waste heat power generation method, system and generator. Background technique [0002] In the industrial process, in order to effectively use the waste heat of flue gas or other gas sources to save energy, the conventional waste heat utilization is to heat water through a single waste heat boiler to generate steam, and the steam enters the steam turbine to expand and perform work to generate electricity. In the conventional steam cycle, only about 30% of the heat energy is converted into electric energy, and 70% of the heat is taken away by the circulating cooling water of the condenser during steam condensation, and the utilization rate of waste heat is not high. In addition, when the steam produced by a boiler with a single steam parameter is used for non-power generation purposes, it is often necessary to reduce the ste...
