In order to improve the flexibility of coal-fired units, a flexible peaking operation method is proposed by combining the heat storage by extracting the reheated steam and secondary air heating by extracting the main steam. Taking the ultra-supercritical 660 MW indirect air-cooled unit as the object of study, the performance of the unit under different peaking schemes at 30% BMCR operating conditions, the energy reuse rates under different heat release conditions and the performance of the combined load reducing operation mode are analyzed. The results show that the energy reuse rates of extracting main steam heat storage, extracting main steam heating secondary air and extracting hot reheat steam heat storage are 55.13%, 84.74% and 46.24%, respectively, at a peak-load shaving capacity of 20 MW with 75% THA heat release condition. Under the premise of ensuring the safety of boiler combustion and heating surface, the combined load reducing operation mode can achieve a peak peak-load shaving capacity of 46 MW, and the energy reuse rate can reach 74% when the heat release condition is 75% THA. This study can provide a reference for flexible peak-load regulation of coal-fired units.

为提高燃煤机组的灵活性,提出一种抽再热蒸汽储热和抽主蒸汽加热二次热风联合灵活调峰运行方式。以超超临界660 MW间接空冷机组为研究对象,分析了该机组在30%BMCR工况不同调峰方案下机组抽汽储热调峰性能、不同的释热工况下的能量复用率以及联合降负荷运行方式的性能。结果表明:在调峰容量为20 MW、释热工况为75%THA时,抽主蒸汽储热、抽主蒸汽加热二次热风和抽再热蒸汽储热的能量复用率分别为55.13%、84.74%和46.24%;在保证锅炉燃烧和受热面安全的前提下,采用抽再热蒸汽储热和抽主蒸汽加热二次热风联合降负荷灵活运行方案,调峰容量可达46 MW,在释热工况为75%THA时能量复用率可达74%。研究结果可为燃煤机组灵活调峰提供参考。

为提高燃煤机组的灵活性,提出一种抽再热蒸汽储热和抽主蒸汽加热二次热风联合灵活调峰运行方式。以超超临界660 MW间接空冷机组为研究对象,分析了该机组在30%BMCR工况不同调峰方案下机组抽汽储热调峰性能、不同的释热工况下的能量复用率以及联合降负荷运行方式的性能。结果表明:在调峰容量为20 MW、释热工况为75%THA时,抽主蒸汽储热、抽主蒸汽加热二次热风和抽再热蒸汽储热的能量复用率分别为55.13%、84.74%和46.24%;在保证锅炉燃烧和受热面安全的前提下,采用抽再热蒸汽储热和抽主蒸汽加热二次热风联合降负荷灵活运行方案,调峰容量可达46 MW,在释热工况为75%THA时能量复用率可达74%。研究结果可为燃煤机组灵活调峰提供参考。

In order to improve the flexibility of coal-fired units, a flexible peaking operation method is proposed by combining the heat storage by extracting the reheated steam and secondary air heating by extracting the main steam. Taking the ultra-supercritical 660 MW indirect air-cooled unit as the object of study, the performance of the unit under different peaking schemes at 30% BMCR operating conditions, the energy reuse rates under different heat release conditions and the performance of the combined load reducing operation mode are analyzed. The results show that the energy reuse rates of extracting main steam heat storage, extracting main steam heating secondary air and extracting hot reheat steam heat storage are 55.13%, 84.74% and 46.24%, respectively, at a peak-load shaving capacity of 20 MW with 75% THA heat release condition. Under the premise of ensuring the safety of boiler combustion and heating surface, the combined load reducing operation mode can achieve a peak peak-load shaving capacity of 46 MW, and the energy reuse rate can reach 74% when the heat release condition is 75% THA. This study can provide a reference for flexible peak-load regulation of coal-fired units.
