Optimizing Study On 2×600MW Direct Air-cooled Unit Of Ningxia Lingwu

Meteorologic condition, plant position and building layout around the air-cooled flat will badly affect heat transfer effect of air-condenser and turbine backpressure, so far to induce the unit tripping out. So it is very important to air-cooled unit that simulation test and realizing all factors influence degree to air-cooled unit heat transfer efficiency. After numerical simulating, the paper lays out the influence rule that natural air affects the air condenser. According to the local meteorologic data, it supplies foundation to direct air-cooled unit design, and helps to reduce adverse influence to the whole unit.
