The present investigation includes a detailed study of the proposed equation for counter flow wet cooling tower using Merkel and Poppe models to show the difference and solutions techniques of the proposed models. A mathematical model has been suggested to construct computer software MATLB R2013 program for simulation of natural draft wet cooling tower for summer (hot and dry) and winter (cold and wet) weather according to Iraqi weather. The fill height changed from (0.2-1.4)m at different water inlet temperature (37 ، 40 ، 45) o C and constant mass flow rate of air .It was found that the range of cooling increases when the fill is high and the cooling range ,relative humidity ,cooling approach ,air temperature change are higher at winter than at summer while the effectiveness and enthalpy change show higher value at summer than winter. Also the mass flow rate of water changed from(1-7.5) kg/s with water inlet temperature 45 o C with constant fill height 1.2 m the result obtained show that tower range ، air temperature change ,are higher in winter than at summer where the enthalpy change and effectiveness show higher values at summer than at winter which matches with the other experimental researches.

Experimental and Analytical Investigation to Improve the Efficiency of Industrial Cooling Tower

Cooling towers make use of evaporation whereby some of the water is evaporated into a moving air stream and subsequently discharged into the atmosphere. As a result, the remainder of the water is cooled down significantly.The process parameters such as inlet air rate, water flow rate and fills porosity have more influence on Thermal performance of cooling tower. The Temperature of outlet water is maintained nearest to inlet air wet bulb temperature to obtain the best Thermal Performance of cooling tower. So current work is to obtain and maintaining outlet water Temperature nearest to inlet air wet bulb temperature. The cooling tower fill is the most critical component in the operation of the cooling tower. The function of the tower fill is to provide a maximum contact surface between the water and the air to promote evaporation and heat transfer. Cooling tower fill accelerates the transfer of heat from circulating water by maximizing the contact area between water and air. So inlet water flow rate, inlet air rate and fill porosity are important factor to maintain the outlet temperature of water nearest to inlet air wet bulb temperature.

A Feasibility Study on the Use of Cooling Towers in Thermal Power Plants Located in Tropical Region

International Journal of Scientific & Engineering Research, 2019

In this work, the feasibility of using cooling towers has been studied theoretically for thermal power plants located in tropical region. Since cooling tower is directly coupled with the condenser of a power plant, the impact of selection of cooling tower on the design of condenser has been assessed. Electrical output of the plant is taken 1200í µí±€í µí±€í µí±€í µí±€ í µí±’í µí±’ and thermal efficiency is taken nearly 60% after superheating, thus around 800í µí±€í µí±€í µí±€í µí±€ í µí±¡í µí±¡ thermal load has been assumed on the condenser. The tertiary coolant water inlet temperature is assumed 28 0 C which is the normal reservoir temperature in tropical regions. Condensers with both single and multiple shell tanks have been studied. Design feasibility was evaluated based on two parameters; tube-side flow velocity and length to shell diameter ratio. From the results, it may be observed that there is no preferable design option for condensers with single shell tank and 2 shell tank, both for with and without cooling tower. For condensers with 3 and 4 shell tanks, multiple preferable design options were obtained. The number of design options is lower for condenser with cooling tower compared to the ones without cooling tower. Also, condenser size is found to be much larger for condensers with cooling towers than without cooling towers. As a result, use of cooling tower is not recommended.

Studies and Experimentation on Cooling Towers: A Review

2015

Cooling tower is one of the important utility in chemical industries. Normally they are used to dissipate heat from heat sources to heat sink. The cooling of hot effluent and process water is required from reuse and environmental point of view. Induced, forced and natural draft cooling towers are used according to the requirements in industries. Natural draft cooling towers use atmospheric air. In forced draft cooling air is forced into the tower using blower. In induced draft cooling towers, air is sucked from other end. The water cooling happens because of humidification of air. The heat lost by water is heat gained by air. Water recirculation is also important aspect in the cooling towers. The effectiveness of cooling tower depends on flow rates of air and water and water temperature. Minimization of heat loss is one of the important aspect of studies carried out by various investigators. The interfacial area between air and water is also crucial factor in cooling towers. Three types of packings used in cooling towers are film, splash and film-grid packings. Also it was observed that drift is one of the important losses in cooling towers. Various shapes of cooling towers are tried by various investigators to study effectiveness. Hyperbolic shape was advantageous due to higher area at bottom. It provides aerodynamics, strength, and stability. The present review is aimed at summarizing studies and research on cooling tower for increasing efficiency and power savings to make it more economical and efficient.
