Embodiment Construction
[0005] First, pressurize the liquid power generation medium ammonia or formaldehyde or propane or propylene or propyne under the pressure of 0.1-5.0 MPa to a pressure of 1.0-50.0 MPa with a pump, and use the high-pressure steam expansion in the existing power generation method The low-pressure steam after power generation or the high-temperature flue gas and radiant heat produced by the boiler or the steam produced by the boiler is heated to make it vaporized, and then expands to do power generation after vaporization. After expanding to a pressure of 0.1-5.0MPa, it is cooled with water or The refrigerated medium is cooled to make it liquefied, and the liquefied power generation medium is repressurized to 1.0-50.0 MPa with a pump as described above, then heated and vaporized by a heat source, and then expanded to generate power.

A novel power generation technique includes: using a pump to pressurize one liquid power generation medium of ammonia, formaldehyde, propane, propylene and propyne under the pressure of 0.1-5.0MPa to the pressure of 1.0-50.0MPa; using low-pressure steam, high-temperature flue gas and radiation heat generated by a boiler, or steam generated by the boiler after high-pressure steam expands to generate power in the existing power generation method to vaporize the liquid power generation medium; allowing the vaporized medium to expand to generate power; using water or freezing media to cool the medium to liquefy the medium after the medium expands to the pressure of 0.1-5.0MPa; and using the pump to re-pressurize the liquefied power generation medium to 1.0-50.0MPa, using a heat source to heat the medium to vaporize the medium, and allowing the medium to expand to generate power.
Description
Technical field: [0001] The invention belongs to the field of electric power industry. Background technique: [0002] The known power generation method uses water vapor as the medium. In this method, the sensible heat and latent heat of water vapor with high potential energy are not fully utilized, resulting in low power generation efficiency. Contents of the invention [0003] The purpose of the present invention is to use a new power generation medium to convert heat into electricity and improve power generation efficiency. The new power generation medium adopted in the present invention is ammonia, or formaldehyde or propane or propylene or propyne. First, pressurize one of the above-mentioned liquid power generation media under a pressure of 0.1-5.0 MPa to a pressure of 1.0-50.0 MPa with a pump, and use the low-pressure steam or The high-temperature flue gas and radiant heat generated by the boiler or the steam generated by the boiler before power generation are heat...
