When pure oxygen combustion is carried out by taking hydrogen fuel as source energy to obtain power, the high-efficiency utilization is basically required, and the combined power cycle device is needed to realize. However, for combined cycle thermodynamic devices comprising a brayton cycle, there is often a difficult-to-coordinate conflict between power, thermal efficiency, and compression process step-up ratio; after extensive analysis, it was found that there is a large temperature difference loss in the combustion process of the high grade fuel.

The solar energy forms a high-temperature photo-thermal heat source through a heat collection technical means, and then thermal work is realized through steam power cycle or gas-steam combined cycle, however, due to factors such as a limited working principle, materials, safety and the like, the application value of the high-temperature heat source formed by solar energy collection is not fully exerted, and still a room for improvement is provided.

Brief description of the hydrogen fuel and solar collector system:

(1) High grade fuel: high grade fuel refers to fuel in which the heat source temperature formed by the combustion products is relatively high.

In contrast, the low-grade fuel, i.e., low-grade fuel, refers to a fuel with relatively low heat source temperature formed by combustion products.

(2) For the reasons of limited current technical conditions or material performance, etc., for the fuel which needs to provide driving high-temperature load for the circulating working medium through indirect means, the grade of the fuel is defined by the temperature which can be reached by the circulating working medium under the current technical conditions, namely, the fuel which can be reached by the circulating working medium (working medium) at a higher temperature is high-grade fuel, and the fuel which can be reached by the circulating working medium (working medium) at a lower temperature is low-grade fuel.

In the invention, the hydrogen fuel combustion product is a cycle working medium; it is evident that the temperature that the circulating working fluid can reach through the solar collector system is lower than the temperature of the high-temperature water vapor formed by the hydrogen fuel in the combustion chamber 4; that is, hydrogen fuel is a high-grade fuel, and photo-thermal belongs to a low-grade fuel.

(3) The solar heat collection system in the application of the invention is also called a solar heat supply system, and refers to a heat supply system which converts solar radiation energy into high-temperature heat energy (photo-thermal for short) by using a heat collector and is used for providing driving heat load for a thermodynamic cycle system; it is mainly composed of heat collector and related necessary auxiliary facilities.

(4) There are two main types of heat supply modes of solar heat collection systems at present: (1) the high-temperature heat energy converted by solar energy is directly supplied to a circulating working medium flowing through a solar heat collection system; (2) the high-temperature heat energy converted from solar energy is firstly provided for a working medium of a self-circulation loop, and then the working medium is provided for a circulation working medium flowing through a solar heat collection system through a heat exchanger.
