Download or read book Vacuum Drop Test of Air Cooled Condensers in Operation written by Hans Georg Schrey and published by GRIN Verlag. This book was released on 2018-04-23 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientific Essay from the year 2018 in the subject Physics - Thermodynamics, , language: English, abstract: Vacuum tightness is critical for air-cooled condensers operating at low absolute pressure. Low vacuum is aimed for because vacuum dominates the power plant efficiency. To verify vacuum tightness usually a vacuum drop test is made with the system empty at normal atmospheric temperature and free of any liquids. This test is done before commissioning of the power unit and generally follows the recommendations of the Heat Exchanger Institute (HEI) as outlined in §6.1.1 of “Standards for Steam Jet Vacuum Systems”. However, over time of operation the power plant may develop leakages, which were not present at the time of the original drop test. This calls for a tightness test at operating conditions where pre-conditions for the standard vacuum drop test are not fulfilled. The report describes a vacuum drop test without interfering too much into normal power plant operation. The test is suitable for stationary operating conditions using standard operation readings. The assessment of leakage flow is based on the measured vacuum decay rate. It is shown that vacuum decay rates taken from tests before and after commissioning are different. Contractual fixing of acceptable vacuum decay rates should therefore be treated with care. Example graphs for easy evaluation are given.

Available in PDF, EPUB and Kindle. Book excerpt: Vacuum systems are in wide spread use in the petrochemical plants, petroleum refineries and power generation plants. The existing texts on this subject are theoretical in nature and only deal with how the equipment functions when in good mechanical conditions, from the viewpoint of the equipment vendor. Also, the existing texts fail to consider the interaction of the vacuum system with the process equipment it serves and the variability of the motive steam conditions, change in cooling water temperature condenser fouling and erosion of the ejectors. Here are some of the many questions answered in this groundbreaking volume: Why does my first stage jet make a surging sound during hot weather? Why does the vacuum suddenly break? I've seen moisture condensing on the jet's body! What’s causing that? Why do I have to steam-out the drain legs from our condensers? Superheated steam is making our vacuum worse. Is this normal? How can I locate and measure air leaks? Reducing the steam pressure to my jets improves vacuum. But why? I can't pull the pre-condenser bundle. The shell side is fouling. What should I do? We're not getting our normal horsepower from our steam turbine. Could this be a jet problem? Raising the seal drum level improves vacuum! Is there an explanation for this? Our turbine exhaust steam pressure to our surface condenser has doubled in the last two years. What should we do? Restricting cooling water flow from our elevated condensers improves vacuum! Is this possible? What's a converging-diverging ejector all about? What's the difference between a barometric condenser and a surface condenser? Which is better?

Download or read book Annular Two Phase Flow written by Geoffrey Hewitt and published by Elsevier. This book was released on 2013-10-22 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: Annular Two-Phase Flow presents the wide range of industrial applications of annular two-phase flow regimes. This book discusses the fluid dynamics and heat transfer aspects of the flow pattern. Organized into 12 chapters, this book begins with an overview of the classification of the various types of interface distribution observed in practice. This text then examines the various regimes of two-phase flow with emphasis on the regions of occurrence of the annular flow regime. Other chapters consider the single momentum and energy balances, which illustrate the differences and analogies between single- and two-phase flows. This book discusses as well the simple modes for annular flow with consideration to the calculation of the profile of shear stress in the liquid film. The final chapter deals with the techniques that are developed for the measurement of flow pattern, entrainment, and film thickness. This book is a valuable resource for chemical engineers.
Download or read book Two Phase Flow Heat Exchangers written by Sadik Kakaç and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 1090 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two-phase flow heat exchangers are vital components of systems for power generation, chemical processing, and thermal environment control. The art and science of the design of such heat exchangers have advanced considerably in recent years. This is due to better understanding of the fundamentals of two-phase flow and heat transfer in simple geometries, greater appreciation of these processes in complex goemetries, and enhanced predictive capability through use of complex computer codes. The subject is clearly of great fundamental and practical importance. The NATO ASIan Thermal-Hydraulic Fundamentals and Design of Two-Phase Flow Heat Exchangers was held in Povoa de Varzim (near Porto), Portugal, July 6-17, 1987. participating in the organization of" the ASI were the Department of Mechanical Engineering and the Clean Energy Research Institute, University of Miami; Universidade do Porto; and the Department of Mechanical Engineering, Aeronautical Eng ineer ing, and Mechanics, Rensselaer Polytechnic Institute. The ASI was arranged primarily as a high-level teaching activity by experts representing both academic and industrial viewpoints. The program included the presentation of invited lectures, a limited number of related technical papers and discussion sessions.

Available in PDF, EPUB and Kindle. Book excerpt: to increase the use of direct contact processes, the National Science Foundation sup ported a workshop on direct contact heat transfer at the Solar Energy Research Insti tute in the summer of 1985. We served as organizers for this workshop, which em phasized an area of thermal engineering that, in our opinion, has great promise for the future, but has not yet reached the point of wide-spread commercial application. Hence, a summary of the state of knowledge at this point is timely. The workshop had a dual objective: 1. To summarize the current state of knowledge in such a form that industrial practi tioners can make use of the available information. 2. To indicate the research and development needed to advance the state-of-the-art, indicating not only what kind of research is needed, but also the industrial poten tial that could be realized if the information to be obtained through the proposed research activities were available.
