PROBLEM TO BE SOLVED: To provide an air-cooled steam condensing device that has higher heat exchange performance than conventional ones, enables a compact design, and is hard to generate dew condensation.SOLUTION: In an air-cooled steam condensing device 11, cooling air F is sprayed toward a condensing pipe unit 21 comprising a plurality of condensing pipes 23 where exhaust steam discharged from equipment flows, then the cooling air cools the condensing pipes 23, and thereby the exhaust steam in the condensing pipes 23 are condensed. The plural stages of the condensing pipe units 21 are arranged with intervals in a cooling air flow direction. Between condensing pipe units 21 adjacent in the cooling air flow direction, provided is a water spray nozzle 24 for spraying water to the cooling air F. 【課題】従来に比べて熱交換性能が高くコンパクト設計が可能であり、しかも結露が発生しにくい空冷式蒸気復水装置を提供する。【解決手段】設備機器から排出される排気蒸気が流れる複数の復水管２３が束ねられた復水管ユニット２１に向けて冷却用空気Ｆを吹き付けて復水管２３を空冷することにより、復水管２３内の排気蒸気を復水する空冷式蒸気復水装置１１において、復水管ユニット２１が冷却用空気の流れ方向に間隔をあけて複数段配置され、冷却用空気の流れ方向に隣接する復水管ユニット２１間に、冷却用空気Ｆに水を噴霧する水噴霧ノズル２４が設けられている。【選択図】図１
