7. COOLING TOWER

7. COOLING TOWER . Syllabus COOLING TOWER : Types and performance evaluation, Efficient system operation, Flow control strategies and energy saving opportunities, Assessment of COOLING towers Introduction COOLING towers are a very important part of many chemical plants. The primary task of a cool- ing TOWER is to reject heat into the atmosphere. They represent a relatively inexpensive and dependable means of removing low-grade heat from COOLING water. The make-up water source is used to replenish water lost to evaporation. Hot water from heat exchangers is sent to the COOLING TOWER . The water exits the COOLING TOWER and is sent back to the exchangers or to other units for further COOLING . Typical closed loop COOLING TOWER system is shown in Figure Figure COOLING Water System COOLING TOWER Types COOLING towers fall into two main categories: Natural draft and Mechanical draft.

Aluminum, glass fiber, and hot-dipped galvanized steel are commonly used fan materials. Centrifugal fans are often fabricated from galvanized steel. Propeller fans are fabricated from galvanized, aluminum, or moulded glass fiber reinforced plas-tic. 7.2 Cooling Tower Performance 7. Cooling Tower Bureau of Energy Efficiency 139

In some more recent boiler houses, the problem has been alleviated by mounting the hoppers over the boilers on calibrated load cells, but these are yet uncommon.
