Description

Hydrogen fuel carrying same light and heat combined cycle power device

Technical field:

The background technology is as follows:

the power demand is the most common in human life and production; the thermal energy is converted into mechanical energy by a thermal power device, and is an important means for obtaining power or electric power by human beings.

In the fuel, hydrogen belongs to high-quality energy, is also high-grade fuel, and is fully utilized; the heat-changing work is realized by using hydrogen as fuel, and the generation and emission of any pollutant can be avoided by adopting pure oxygen to support combustion. When hydrogen fuel is taken as input energy to obtain power, the requirement for obtaining efficient utilization is fundamental, and the requirement is to be realized by a combined power cycle device. 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 also a significant temperature differential 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 a large improvement space is still provided.

Brief description of the hydrogen fuel and solar collector system:
