Abstract: Under the background of developing energy-saving and emission-reduction economy advocated by the country, as a new type of natural draft cooling tower(NDCT) featuring outstanding achievements in energy saving and noise reduction, the super high-level water collecting natural draft cooling tower is bound to receive much more attention and applications with its successful commitments in oversea nuclear power stations as well as a domestic 1 000-MW thermal power plant. Different from the conventional NDCT technology, it is unique in its instrument configuration, specification and control philosophy. To take advantage of this technology, from the viewpoint of fossil fuel power plant engineering design, this paper conducts an in-depth study on the instrumentation and control features of super high-level water collecting natural draft cooling towers, and then proposes the engineering design.
