Problems solved by technology

[0008] Existing methods for efficient exergy generation using superheated steam have limited technological potential due to the low thermodynamic efficiency of converting heat into work, which prevents growth in conversion efficiency due to the large heat loss caused by the steam condensation process Caused by the waste of effective energy outside the system

Embodiment Construction

[0022] The principle of the invention will now be explained in detail by explaining the invention based on a thermodynamic steam cycle process, an example of which is illustrated in the accompanying drawings. The examples mentioned here are intended to explain the present invention but not to limit the present invention in any way.

[0023] According to the present invention and its embodiments, an initial flux of a dry saturated steam working medium is generated which, without changing its state of aggregation, undergoes a steam power cycle in the single-phase region. In the compression stage of the vapor working fluid, some part of the working fluid in the liquid state will be additionally injected into the compression chamber, and the injected working fluid will be completely evaporated in the compression chamber, and the heating of the working fluid will be removed under compression . The amount of injected liquid working medium is preferably adjusted at regular intervals...

Abstract

The invention relates to a process for transforming energy into exergy by supplying heat to a vaporous working substance subjected to an expansion and compression cycle and by obtaining the exergy in the expansion stage of the cycle. The cycle is performed in a single phase area of the vaporous working substance and working substance in liquid state is supplied to the cycle during the compression stage.

Description

technical field [0001] The present invention relates to power-engineering and in particular to a method of generating exergy (effective fraction of energy) by converting heat into useful mechanical or electrical work. [0002] More specifically, the present invention relates to a process for converting the energy of a heat source into a useful form by means of a working fluid that expands or compresses in a continuously cyclic thermodynamic kinetic process. With the help of a homogeneous single-phase working fluid in a dry steam state, heat is converted into useful mechanical and electrical energy. When continuously in the region of steam (such as water vapor) without changing the state of aggregation, the working medium periodically expands or compresses, so that the supplied thermal energy is transferred to the superheated steam in the region of high entropy Expansive useful work conversion. [0003] The invention also relates to a method of increasing the thermodynamic ef...
