Description

Technical field: [0001] The invention belongs to the technical field of thermodynamic (electricity) cogeneration and heat pump. Background technique: [0002] In the thermodynamic cycle device using water vapor as the circulating medium, in order to make the power machine (steam turbine) have a higher internal thermal efficiency and increase its operational safety and reliability, it is required that the pressure and temperature of the exhaust steam of the power machine should not be too low; , the ambient temperature is low, and the exhaust temperature of the power engine is high, there will be a temperature difference of about 40°C or even higher between the two, which cannot be utilized; moreover, in the steam power cycle system represented by thermal power plants, Although the grade of the exhaust steam is very low, the remaining heat load is often very rich, and it is of great significance if it can be used effectively. [0003] The existing combined heat and power sup...
