Surface Condenser

Surface condenser generates vacuum backpressure to ensure output of turbine, and also condenses a waste-steam while located at the end of steam turbine which is generally used in industries such as power generating in power plant, compressing in chemical plant as well as propelling of LNG tanker. The produced condensate is going to be re-circulated towards boiler passing through feed water pump, feed-water heater and deaerator.
Depends on location of surface condenser against turbine, it is classified into Top-entry type and Side-entry type. The circular type surface condenser is used for small size and medium size while square type surface condenser is used for large size such as power plant. The function of surface condenser is to maintain back pressure & the power of turbine for generator driver, compressor driver and propulsion of LNG carrier while exhausted steam from turbine is condensed. The condensed feed water in surface condenser is recirculated to boiler through feed water heater and deaerator.

PCHE

[PCHE(Printedcircuitheatexchanger)] PCHE(Printed Circuit Heat Exchanger)는 고온고압의 진공 환경 조건에서 모재와 모재 사이의 표면에서 발생하는 계면 확산 현상을 이용하여 모재와 모재를 접합하는 제품입니다. 열교환 형태는 Plate Type과 유사하나, Plate-Plate 간의 구조적 결합이 모재의 기계적 특성을 유지하는 장점으로 고온 및 초저온, 고압 환경에서 사용 가능한 특성이 있습니다. Compact한 특징의 열교환기로 선박에서는 주로 LNG 운반선의 BOG 재액화장비(초저온), 고압 기화기, Compressor Cooler 등으로 사용하고 있습니다. 육상용으로 수소연료전지의 폐열회수, 개질, SCO2 발전, 수소충전소 등에 사용하고 있습니다. 특히 ㈜동화엔텍은 수소충전소의 H2 Pre Cooler(700bar)를 최고품질로 공급하고 있습니다. #동화엔텍 #DongHwaEntec #PCHE #Printedcircuitheatexchanger

Fresh Water Generator Fresh Water Generator is used to desalinate seawater for the ships. There are two types fresh water generator, R/O type and Low-pressure vapor type. Low-pressure vapor type is most widely used in commercial ships because it utilizes wasted engine jacket water or steam while sailing. The engine jacket water and steam can be utilized as a heat-source, and Shell & Tube type and Plate type are available. The seawater is heated by various heat-sources under the vacuum state, and then vaporized accordingly. The vaporized seawater is desalinated in separate filtering unit before condensed, and then fresh water is produced. Meanwhile, a salinity of produced fresh water shall remain at 0~10 ppm . Fresh Water Generator is comprised of vaporizer, condenser, demister, salinometer, distillate pump, ejector and steam injector. Multi-stage Fresh Water Generator can achieve high efficiency when large amount of fresh water is required with small amount of calories due to
