Abstract: Based
on the analysis of air flow and heat transfer in the dry-cooling
tower for Harmon system, a combined iteration method is
presented to solve the coupled heat transfer and draft equations
derived from theoretical and empirical formulas, with the size
of the exchangers and the cooling tower or the systematic
parameters being determined. Taking the 686 MW unit as an
example, the present calculating results are well agreed with
those of the real case, and thus the method presented is
practical and feasible for reasonable design of Harmon system.
Key words:
