Experimental investigation on condensation heat transfer for Bundle Tube heat exchanger of the PCCS (Passive Containment Cooling System)Annals of Nuclear Energy, 2020Co-Authors: Yu-sun Park, Kyoung-ho KangAbstract:
Abstract To provide a passive cooling system for the reactor containment, Passive Containment Cooling System (PCCS) was adopted in the design of i-POWER nuclear power plant. This study focused on validation tests for condensation heat transfer of the PCCS heat exchanger using the CLASSIC facility. The tests include investigation of the condensation heat transfer in prototypic single Tube and Bundle Tubes. From the single Tube experiments, condensation heat transfer model was proposed to reflect the PCCS heat exchanger Tube geometry. Experimental results in the Bundle Tube show consistent trend compared to the proposed heat transfer model from the single Tube test. The local condensation heat transfer coefficient of inside Tubes was smaller than the average value due to a shadow effect by a larger mass fraction of non-condensable gas, so that design of the PCCS should take into account degradation of the condensation heat removal in the Bundle geometry.

Application of Thermocouple Thermometry and Bundle Tube Monitoring in Fire Prevention and Extinguishing in Coal Mine2009 2nd International Congress on Image and Signal Processing, 2009Co-Authors: Xiyu Pi, Yinghua Zhang, Yuhuai Wang, Zhian Huang, Xiaobo ZhangAbstract:
Spontaneous combustion occurred many times in the goaf of E12606 Fully Mechanized Working Face of Cuijiazai Coal Mine. For reinforcing fire prevention and extinguishing management, thermocouple thermometry and Bundle Tube monitoring system had been laid in the goaf of E12606 working face. Through analyzing the measurement result (temperature and oxygen change rule), distribution regularities of three zones of spontaneous combustion and working-face propulsion speed had been determined for the goaf. This research provides technical support for Cuijiazai Coal Mine to prevent spontaneous combustion and arrange production rationally.

Inquiry specs can improve air-cooled condenser designPower Engineering, 1990Co-Authors: M. W. LarinoffAbstract:
Air-cooled steam condensers, commonly used in the process industry, have found acceptance in power plants. Reasons that they may be installed include a plant’s lack of makeup water, high water costs, or a need to eliminate water vapor plumes or chemical blowdown. Although they once were thought to have size limitations, such condensers are in use at several 650-MW power plant units. Now used in large power plants, air-cooled steam condensers can minimize Bundle Tube freezing problems through good design specification and operating practice
