Experimental Study of The Performance Characteristic an Induced Draft Cooling Tower with Variates Fillings

Abstract

The aim of this research is designing and testing an Induced Draft Cooling Tower (IDCT). The Cooling tower is the main instrument which used to cool the hot water from the condenser and release heat into the atmosphere at a power plant. Temperature is maintaining as cool as original condition. One of the components of the cooling tower is filler. It is very influential on IDCT performance, where the contact surface between water and air is expanded and the contact time is extended. An experimental study to evaluated the heat and mass transfer coefficient is conducted. A heat transfer correlation is developed; a new variable is defined. The effect of controlling parameters such as range of temperature, heat rejected rates, effectiveness has been analysed. IDCT was filled with a straight, zigzag and wave filler. The results indicate that the tower characteristics increase with increase cold air velocity, with the variation of filler, the highest tower characteristics get from wave filler arrangement.
