Replacement Of The Concrete Cooling Tower By Steel Structure Cooling Tower During The Operation

摘要

Just like any other item, structure or system, even cooling tower materials, cooling technologies and cooling tower structures are developed. Cooling tower structures range from wooden structure across concrete structure to steel structure or fiber reinforced plastic (FRP) structure. Even fan unit has history of its own. Fan blade shape, impeller's hub size and different materials are developed to increase fan impeller efficiency. Integral part of the whole fan unit is a motor. Standard solution includes gear box, driving shaft and motor. But what is standard solution? Today's trend is to eliminate critical maintenance parts, to be environment friendly and extend total service time. Based on this description standard solution can be slow-running motor, which is directly coupled with fan impeller, where all mentioned advantages are included. Last but not least is the heart of cooling tower - cooling fill. We can discuss both main types - splash or film, several cooling fill materials, cooling fill geometry, flute size and type of sheets connection can be discussed as well.
