Paper Title
Review on wind effect and axial fan performance of Air Cooled Condenser for a thermal power plant
Abstract
Economic and environmental restrictions have resulted in an increase in the installation of air-cooled condensers (ACCs) in thermoelectric power plants located in arid regions. [7]Air-cooled condensers overcome one of the main issues facing the construction of Thermal power plants by replacing water with air as the medium for cooling of the steam turbine waste heat. [2]Forced flow air-cooled heat exchangers (ACHEs) as found in the petro-chemical, process and power industries use fans arranged in single or multiple fan rows to force air over finned tube bundles.Any flow disturbances or distortions experienced at the inlets of these fans tend to reduce the effectiveness of the ACHE.Air-cooled heat exchangers (ACHEs) which utilize large arrays of axial fans, commonly suffer from inlet flow losses related to off axisflow into the fans. [1] Forced draught air-cooled heat exchangers (ACHEs) are often arranged into banks consisting of multiple rows of fan-heat exchanger combinations. Fans on the outer edge of the banks are subject to severe cross-flow conditions as the air is swept past route to fans located deeper within the banks. The cross-flow conditions give rise to increased inlet flow losses. [3] The losses which are occurs in Axial fans are Secondary loss. The various losses areidentified and a numerical example is given that clearly illustrates the significance of so-called "secondary losses" in a practical air-cooled condenser unit. It is shown that the sum of the "secondary losses" may be of the same order as that of the heat exchanger bundles under normal flow conditions. [1]
