Improving cooling efficiency and fouling removal of fill pack cooling tower by using chemical

Abstract

The major consideration for all power generation plants is sustainable the profitable by operating for cooling towers effectively. If the cooling tower efficiency is less than design, this can increase heat rate penalty. Normally, filled pack material of cooling towers in power generation plant has experienced of gradual loss in thermal performance. The loss in efficiency is usually involved with fouling in fill packing. The objective of the research is to increase the cooling efficiency to specify design by removing fouling matter from filled pack by chemical detergent. And determine the suitable chemical dosage. Detergent can removes surface deposits through a combination of chemical solubilization and physical scrubbing by entrained air bubbles. The study was performed at load megawatt 40 and 50 MW and dosage of detergent was varied between 0, 3, 5 and 10 mg/l. The result show 0.45% increasing of cooling efficiency compare with design when detergent was dosed at 3 mg/l at load megawatt 40 MW. And 10.12% increasing of cooling efficiency compare with design when detergent was dosed at 5 mg/l at load megawatt 50 MW.
