An Investigation of Air-Cooled Steam Condenser Performance Under Windy Conditions Using Computational Fluid Dynamics J. Eng. Gas Turbines Power (June, ) Simulating the Effect of Wind on the Performance of Axial Flow Fans in Air-Cooled Steam Condenser SystemsCited by: Performance trends of an air-cooled steam condenser under windy conditions Spray cooling of the inlet air or the addition of an evaporative cooling system can also be considered for improving performance under extreme conditions. The present numerical study models the air flow field about and through an air-cooled steam condenser under Author: J. A. Van Rooyen. Ambient wind has adverse impacts on the thermal-flow performances of air-cooled steam condensers (ACSCs). It is useful to understand the mechanisms of such influences so as to improve and optimize the performance of condensers. The flow fields around an ACSC at different wind speeds and directions are numerically investigated in this by: 4.   The effect of porous wind screens, installed in a cross-type arrangement below the fan platform, on the performance of El Dorado Power Plant’s 6 × 5 fan air-cooled steam condenser (ACC) under windy conditions is investigated using computational fluid dynamics.

Performance Trends of a Large Air-Cooled Steam Condenser during Windy Conditions F.G. Louw Department of Mechanical and Mechatronic Engineering, University of Stellenbosch, Private Bag X1, Matieland , South Africa. Thesis: MScEng (Mech) March Large air-cooled steam condensers (ACSC's) nd application in power stations. Direct air-cooled power plant is popularized in north China because of the water conservation. Different from the water-cooled condenser, the ambient air absorbs the latent heat that turbine exhaust in the heat exchangers releases. In this paper, the numerical model of a 2×MW power plant is prepared to simulate the performance of the air–cooled steam condenser under different wind speeds.   1. Introduction. The application and popularity of air-cooled condensers (ACCs) is increasing in the power plants throughout the countries that are short of water resources during the last decade,.Due to the direct utilization of ambient winds as the cooling medium of the exhaust steam from turbine, the environment conditions such as the ambient temperature, wind speeds and directions . Air-cooled steam condensers (ACSCs) are so sensitive to the unpredictable ambient conditions that it is quite necessary to find the mechanism how the ambient conditions get into reaction and reasonable measurements can be employed to improve the performance. The numerical model of an ACSC cell is established in the paper.

Corpus ID: Steam flow distribution in air-cooled condenser for power plant application @inproceedings{HoningSteamFD, title={Steam flow distribution in air-cooled condenser for power plant application}, author={Werner Honing}, year={} }. Air Cooled Steam Condensers • Air Cooled Condensers Types • Natural Convection: Occurs when a heater with a reduction of dense fluid is pressed left by a cooler denser fluid. • Forced Convection: Occurs when an outer force pushes a fluid, such the same as water of air, to create it move about and transfer heat. • Geometrical Designs. Inlet air flow distortions in a large air-cooled steam condenser (ACSC), caused by structures, wind and other fans may result in a significant reduction in fan performance, or volumetric effectiveness, as well as fan blade vibration. This phenomenon has an adverse effect on the heat rejection capacity of an ACSC due to a decrease in air mass flow rate.
