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.
