Description

Fuel carrying same photo-thermal regenerative thermal cycle device
Technical field:
the invention belongs to the technical field of thermodynamics and thermal dynamics.
The background technology is as follows:
the fuel has different types and different properties, and the temperature of fuel gas formed by the combustion of the fuel directly determines the heat-changing work efficiency; limited by one or more factors such as the operating principle, the nature of the working medium, the nature of the materials, the manufacturing level of equipment and other components, and the like, in a thermodynamic device adopting high-grade fuel, the combustion process has larger irreversible loss due to temperature difference. The solar energy forms a high-temperature photo-thermal heat source through a heat collection technical means, and then a thermal power device can be utilized to realize thermal power, however, due to factors such as a working principle, materials, safety and the like, the power application value of the high-temperature heat source formed by solar energy aggregation is often not fully exerted, and a large lifting space exists.
The gas power device adopting the brayton cycle as the working principle or the gas-steam combined cycle power device is a main means for converting high-temperature heat load formed by fuel combustion into power. In order to improve the power application value of high-temperature heat load, the average temperature of the heat absorption process of the circulating working medium is improved as much as possible, and the temperature and the quantity of the heat emission load of the aerodynamic device are reduced. In the prior art, when the temperature formed by the high-temperature heat load obtained by the circulating working medium is higher, the temperature of the circulating working medium discharged by the expander is also increased, so that the difficulty of reducing the heat load discharged by adopting the traditional heat regeneration technology is also increased. The increase in the temperature and the increase in the number of the exhaust heat loads affect the maximization of the heat-altered work efficiency, both for the aerodynamic power cycle device itself and for the following rankine cycle power device.
The invention provides a fuel carrying same photo-thermal regenerative thermal cycle device which has the advantages of high thermal efficiency, strong safety, simple structure and the like, greatly improves the utilization rate of photo-thermal conversion into mechanical energy and remarkably reduces the construction cost of a power device.
