某350 MW超临界热电联产机组运行补水雾化技术优化研究

Optimization of Water Replenishment Atomization Technology for a 350 MW Supercritical Cogeneration Unit

超临界热电联产机组将凝汽器的正常运行化学补水通过喷嘴雾化后补入凝汽器可以有效降低主凝结水的过冷度和含氧量,进一步提高回热系统热经济性和降低机组发电煤耗,最终达到节能降耗目的。

The supercritical cogeneration unit can effectively reduce the supercooling degree and oxygen content of the main condensate by feeding the chemical water supplement into the condenser after atomizing through the nozzle during the normal operation of the condenser, further improve the thermal economy of the regenerative system and reduce the coal consumption of the unit for generating electricity, and finally achieve the purpose of energy saving and consumption reduction.
