摘要
针对超超临界空冷机组滑压曲线存在的问题,提出对传统滑压曲线的优化方案。通过试验确定超超临界空冷机组在不同背压、不同负荷工况下的最优的滑压曲线,采用背压和负荷为二维变量,形成动态的滑压曲面,确定最优主汽压力。在保证调节性能的前提下,最大程度降低高调阀节流损失,提高机组经济性,发挥超超临界机组的节能优势。
In view of the problems in slip pressure curve of ultra supercritical air cooling units, an optimization scheme for traditional sliding pressure curve is proposed. Through tests to make sure that the ultra supercritical air cooling unit has the best sliding pressure curve in different backpressure and load. To get the best main steam pressure, it uses backpressure and load as two-dimensional variable to form a dynamic sliding pressure curve under the premise of adjusting performance, it will cut down high pressure valve throttling and improve economic efficiency of the unit.
