The invention provides a single-working-medium combined cycle steam power device, and belongs to the technical field of energy and power. A condenser is provided with a condensate pipeline which communicates with a hybrid evaporator through a circulating pump, an expansion machine is provided with a steam channel which communicates with the hybrid evaporator, the hybrid evaporator is also providedwith steam channels which communicate with a pressure expanding pipe and a second expansion machine respectively, the pressure expanding pipe is provided with a steam channel which communicates withthe expanding machine through high-temperature heat exchanger, and the second expanding machine is provided with a steam channel which communicates with the condenser. The high-temperature heat exchanger is provided with a heat source medium channel which communicates with the outside; the condenser is also provided with a cooling medium channel which communicates with the outside; the hybrid evaporator is also provided with a heat source medium channel which communicates with the outside; and the expanding machine and the second expanding machine are connected with the outside and output power to form the single-working-medium combined cycle steam power device.
Description
Technical field: [0001] The invention belongs to the technical field of energy and power. Background technique: [0002] The conversion of thermal energy into mechanical energy is needed for human life and production; the single-phase combined cycle steam power plant that uses the principle of combined cycle is of great significance in the field of heat conversion of non-high-quality fuels. From the point of view of the components that constitute the single working medium combined cycle steam power plant, the expander, compressor and heat exchanger are essential basic components and core components; among them, the two core components of the compressor and expander are difficult to manufacture , high material requirements and high manufacturing costs—this has a negative impact on its application. Therefore, efforts should be made to reduce the number of compressors or expanders, or replace them with simple components, which will significantly reduce the manufacturing diffic...
