Bacteria and mold adhere to the deposits and so on. This causes the heat transfer coefficient to be reduced, corrosion to form under the deposit and reduces efficient heat distribution throughout the pipe. The rubber ball method of cleaning, which requires periodically shutting down the system, is not ideal. Installing a twisted tape in the pipe reduces the stagnant, flat surface areas by causing the water to spiral so the water currents constantly sweep the surfaces and help to reduce the formation of deposits. This anti-fouling system increases the heat transfer, helps energy conservation, and makes the system dependable, stable, and less maintenance requisite.下载后可任意编辑Key word: condenser; twisted tape; Dirt; Anti- filthy; Strengthened heat transfer. 下载后可任意编辑0 前言: 凝汽器是汽轮机组的一个重要组成部分, 其作用是将汽轮机排汽冷却凝聚成...
