Abstract

The invention discloses a system coupling an IGCC power station and air liquefaction equipment and a working method of the system. The system comprises an IGCC power station power generation system, a peak regulation and frequency modulation control module, a power transmission and transformation and power supply module, an air separation device, a liquefied air energy storage tank, a liquefied air evaporation expansion unit and a liquefied air generator. According to the system coupling the IGCC power station and the air liquefaction equipment, the air liquefaction equipment and the liquefied air energy storage tank are utilized to quickly change the power supply power and load characteristics at any time, and the peak regulation and frequency modulation load requirements of a power grid on the IGCC power station are met.

Description

technical field [0001] The invention belongs to the field of IGCC power generation, and in particular relates to an IGCC power station coupling air liquefaction equipment system and a working method thereof. Background technique [0002] The global climate issue has attracted more and more attention from people, and the "low-carbon economy" characterized by low energy consumption, low emission and low pollution has become a hot spot in the global political and economic game. my country's power supply is mainly based on coal power. In order to reduce soot-type pollution, vigorously developing coal-fired technology is a research direction that improves coal use efficiency, reduces pollution, and is economically feasible. IGCC power generation technology not only has the high efficiency of combined cycle, but also solves the environmental pollution problem caused by coal-fired power generation. [0003] IGCC is a clean coal power generation technology that organically integrat...
