Abstract

본 발명은 증기응축장치에 관한 것으로, 특히 열파이프기술도 함께 사용하여 어떠한 주위환경하에서도 빙결되지 않으면서 간단한 비응축성기체의 처리방법을 제공하는 공랭식(空冷式) 증기응축기에 관한 것인 바, 병류하는 증기와 응축물은 하향 유동하면서 증기흐름이 주응축기를 통하여 유동하는 한편, 모든 증기가 완전히 응축되지 않음으로써 증기가 각 튜브열을 통하여 계속 배출되도록 열전달표면지역과 송풍기공기유동이 고안되는데, 이와 같은 계속적인 증기흐름에 의해 튜브열내의 비응축성 기체들이 일소되고, 잉여증기는 하부헤더를 거쳐 열파이프가 구비된 제2응측기로 유동하며, 이 제2응축기부분내의 열파이프의 증발기측 외표면상에서 상기한 잉여증기가 응측된다. 하부헤더내의 비응축성 잔류기체들이 종래 응축기의 것과 유사한 공기제거시스템에 의해 배기되고, 하부헤더내의 응축물은 전력발전사이클에서의 재사용을 위해 수집된다.The present invention relates to a vapor condenser, and more particularly, to an air-cooled vapor condenser that uses a heat pipe technology together to provide a simple method of treating a non-condensable gas without freezing under any surrounding environment. The heat transfer surface area and the blower air flow are designed so that cocurrent steam and condensate flows downward while the steam flows through the main condenser, while all steam is not completely condensed, allowing steam to continue to flow through each tube row. As a result of the continuous steam flow, non-condensable gases in the tube row are burned out, and excess steam flows through the lower header to the second condenser equipped with a heat pipe, and outside the evaporator side of the heat pipe in the second condenser portion. The surplus steam mentioned above is condensed on the surface. Non-condensable residual gases in the lower header are exhausted by an air removal system similar to that of conventional condensers, and the condensate in the lower header is collected for reuse in the power generation cycle.
