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 thermal power can be realized by hydrogen fuel, conventional fuel, photo-thermal and conventional heat resources represented by industrial waste heat; the same or different thermal power principles are adopted, and corresponding construction cost is paid by utilizing different system devices, so that the conversion of hydrogen fuel, conventional fuel, photo-thermal or conventional thermal resources into mechanical energy is realized; obviously, it is of positive interest to try to reduce the number of thermal power devices.

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 method is limited by factors such as working principle, working medium property, material property, equipment and the like, the temperature difference irreversible loss exists in the hydrogen combustion process, the temperature difference irreversible loss exists in the conventional fuel combustion process, and the temperature difference irreversible loss exists in the photo-thermal application process; there is room for improvement in heat-altered work efficiency of conventional heat resources, particularly medium/high temperature heat resources, represented by industrial waste heat.

In order to increase the thermal efficiency, it is necessary to bring the circulating medium to as high a temperature as possible after the high-temperature load is obtained; however, at this time, the temperature of the circulating working medium discharged by the high-temperature expander is increased, the heat discharge is increased, and the heat transfer temperature difference loss in the thermodynamic system is increased, which has an adverse effect on the improvement of the heat-variable work efficiency.
