Title:
COMBINED HEAT AND POWER GENERATION SYSTEM BASED ON HIGH TEMPERATURE AND LOW TEMPERATURE THERMAL STORAGE MEDIA
Document Type and Number:
WIPO Patent Application WO/2022/217758
Kind Code:
A1
Abstract:
A combined heat and power generation system based on high temperature and low temperature thermal storage media, which comprises a low temperature thermal storage apparatus, a high temperature thermal storage apparatus, a compressor system (3) arranged between the low temperature thermal storage apparatus and the high temperature thermal storage apparatus, a thermal power generation apparatus, and a user of heat (7); the low temperature thermal storage apparatus is formed from a low temperature thermal storage medium storage tank (1) and a low temperature pool (2) being connected by means of a working medium pipe, the high temperature thermal storage apparatus is formed from a high temperature thermal storage medium storage tank (4) and a high temperature pool (5) being connected by means of a working medium pipe, and the compressor system (3) is used for compressing low temperature saturated steam output from the low temperature pool (2) and inputting said steam into the high temperature pool (5); and the compressor system (3) and the thermal power generation apparatus are both in communication with a power grid (8), and acquire from or supply power to the power grid (8). The combined heat and power generation system is a highly efficient energy storage and peak regulation device. In the system, power and heat can simultaneously be stored, and power and heat can also simultaneously be provided, irreversible losses during energy storage and use can be satisfactorily reduced, and energy utilization efficiency and exergy efficiency are greatly improved.
