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.

Download or read book Review of the vacuum decay test in air-cooled steam condensers written by Hans Georg Schrey and published by GRIN Verlag. This book was released on 2019-03-06 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polemic Paper from the year 2018 in the subject Engineering - System Science, , language: English, abstract: Condensing the capacity of air-cooled condensers is critical for proper functionality of steam cycles in power plants. Condensers operate in the low vacuum regime to promote the efficiency of power generation. Leakages enable ingress of ambient air into the steam cycle and thus impede condensation and power generation capacity. Therefore, vacuum tightness is essential for effective plant operation and must be verified by means of an acceptance test. The latest revision of the VGB acceptance test code for the air-cooled condenser (VGB-S-131) proposes a simple procedure to verify ample vacuum tightness and evacuation capacity. However, the following report will demonstrate that the informational value of test results in connection with the proposed procedure are to some extent questionable. They cannot stand for themselves but need to be accompanied by further information gathered from other tests, as for example thermal performance tests. This puts the usefulness of the test itself into question.

Available in PDF, EPUB and Kindle. Book excerpt: Scientific Essay from the year 2017 in the subject Physics - Thermodynamics, course: Heat transfer engineering, language: English, abstract: Air-cooled condensers ("ACC") operating in vacuum are widely used at the cold end of contemporary thermal power plants. Proper functioning of the condenser is paramount for power plant efficiency. To adapt to changing process conditions because of changed ambient air temperature or power station load ACC streets are either taken out of or into service or, module fan speed settings are selected appropriately. Even if all fans are running at same speed local variations of cooling air flow may arise as a consequence of e.g. fan location or local wind impact. The designer must ensure that no negative effect (i.e. no cold spot) may evolve at the steam side of the ACC caused by uneven air side cooling or fan control. The following note describes a theoretical method to assess the effect of air flow variations on ACC performance and provides simple rules to avoid potentially risky situations. An important role for safe operation plays the size of the secondary condenser. The procedure may be used as a guideline for proper sizing of the secondary condenser with respect to airflow maldistribution.

This book was released on 2023-01-05 with total page 73 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bachelor Thesis from the year 2018 in the subject Engineering - Mechanical Engineering, grade: 1, Savitribai Phule Pune University, formerly University of Pune, course: Bachelors in Mechanical Engineering, language: English, abstract: Evaporative cooling takes advantage of the potential of the outside air in dry climates to absorb moisture, which results in a temperature reduction of the air stream. But one of the major drawbacks is the continuous scale built up on condenser tubes which makes a barrier between tubes and water sprayed on them, which in turn drastically reduces the heat transfer. This results in a loss of plant efficiency and increases annual refrigeration costs as the compressor work increases for compensating the pressure drop due to scaling. In HVAC around 27% of worldwide energy is consumed only for different HVAC applications. This project mainly focuses on this problem statement, if the scale is 0.06mm then condenser performance decreases by 16%. A mainly evaporative condenser is used in different HVAC applications. In order to overcome this problem, regular maintenance of the condenser should be done by descaling the coils. Various descaling methods are being used in industries descaling like mechanical descaling, chemical descaling, etc. But manual descaling is preferred over other methods due to its simplicity, less cost, and reliability. Yet there are some problems in manual descaling like the number of rows of condensing tubes is very large in numbers and also the pitch between them is less so it becomes very difficult to reach the deep portion of the evaporative condenser in order to clean them thoroughly and effectively scale removal.

Download or read book Air-Cooled Condenser Operation under Varying Ambient Conditions written by Hans Georg Schrey and published by GRIN Verlag. This book was released on 2024-02-29 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientific Study from the year 2024 in the subject Physics - Thermodynamics, , language: English, abstract: The objective of this report is to make up for the following deficiencies at least on a general level – while still using first principles. Air-cooled condensers are widely used at the cold end of thermal power cycles. With this equipment cooling water required in wet cooled power plants may be saved on a large scale. To operate fans which convey dry cooling air to the condenser modules electric power is required which reduces overall power plant effectiveness. Consequently, pumping power consumption should be as small as possible. During operation it is therefore common to reduce fan power consumption by switching down or off fans of individual modules or, in some case complete ACC streets if ambient conditions and operation parameters are promising. Performance guarantees are normally specified with all equipment in full action. Only primary variable variations such as ambient temperature, ambient air pressure or total steam flow rate for a reduced range at fan full speed are part of the performance guarantee. Therefore, effects of fan switch or high cross-wind levels remain open issues.
