Summary

The performance of the fan array in the air-cooled steam condensers (ACSCs), which consumes a large amount of the power from the generator, always affects the characteristics of the whole power plant under the effect of the meteorological conditions. As a result, it is significant to optimize the fan mode to obtain a maximum operation efficiency of the air-cooled thermal system. In the paper, a 2 × 600 MW power plant is modeled to investigate the influence from the fan rotating speed on the performance of the fan array as well as the whole air-cooled power plants. It is found that the promotion of the fan rotating speed of the windward fans improves the performance of the fan array and the heat transfer characteristics of the exchangers in the air-cooled steam condenser, and the beneficial net power in consideration of the fan consumption is also raised effectively with an improved thermal efficiency of the closed Rankine cycle.
