Abstract

Abstract - The conditioning tower is a vertical evaporative cooling tower. Designed to reducing the temperature of the gas for lower temperature thermal processing. The gas of suspension preheater (SP) use for drying and transportationing in the Raw mill and Coal Mill, before be discharged into the environment through out the stack. The installation of the clean water piping system will be channeled to the conditioning tower, it use a spray that functions to reducing the temperature, pressure, and volume of gas that still contains the required dust. It’s removed before being channeled to the back filter, which final product is gas through the stack. Then perform calculations starting from headloss, pump head, pump power, and a amount of water needed. Modeling analysis with the help of pipe flow expert software in order to make comparisons with the calculations carried out and estimate the cost of the material needed. The total head pump obtained is 63.763 m and the pump power is 30.536 kW. The efficiency of manual head pump calculation with software is 3.13 % and pump power is 4.39% which is not more than the tolerance value 6.67% .The minimum amount of water needs is 55,944.3 liters with a usage period of 60 minutes. The estimated value of material costs is Rp. 458,567,125.
