| Abstract: | Based on the investigation in the direct air cooling system abroad and combining with the design of direct air cooling system of 600 MW generating unit in Datong No.2 Power Plant, this paper analyzes, calculates and contrasts the noise control problem of draft fan group in the direct air cooling system; puts forward: the selection standard of single fan's noise satisfying the noise standard within plant's boundary; the reasonable distance of air cooling platform border to the enclosing wall of plant; to set up the protective region of noise; and the other measures on reducing the noise of draft fan group. |
