Description

Hydrogen energy type multifunctional combined cycle steam power device

Technical field:

the invention belongs to the technical field of thermodynamics and thermal dynamics.

The background technology is as follows:

the hydrogen fuel and the photo-heat can realize thermal work; the same or different thermal power principles are adopted, and different system devices are utilized to pay corresponding construction cost, so that the conversion of hydrogen fuel or light and heat into mechanical energy is realized; obviously, it is of positive interest to try to reduce the number of thermal power devices.

The fuel has different kinds and properties, and the temperature of the fuel gas formed by the combustion of the fuel determines the heat-changing work efficiency. Hydrogen is a high-quality and high-grade fuel, and people can use pure oxygen to support combustion so as to avoid the generation and emission of any pollutant; the hydrogen combustion process is limited by factors such as working principle, working medium property, material property, equipment and the like, and has larger irreversible loss due to temperature difference.

In order to improve the efficiency of converting solar energy into mechanical energy, high-temperature photo-thermal is the main direction of solar energy utilization and development; correspondingly, the construction cost of the solar heat collection system is increased significantly. Analysis shows that the dynamic application value of photo-heat is difficult to be improved in the same proportion along with the improvement of the photo-heat temperature due to the influence of the working principle, materials, thermodynamic cycle and the property of working medium.

It is not an easy matter to build an integrated thermodynamic cycle technology with high thermodynamic perfection, reasonable flow and simple structure across the class and heat source grade barriers, and reduce the construction cost of a thermal power system so as to realize high-value power application of hydrogen fuel, high-temperature photo-thermal and medium-temperature photo-thermal.
