77-08: Fan Performance Consideration in Cooling Towers SoundOf concern to the user of a Mechanical Draft Cooling Tower are the performance, efficiency, and structural integrity of the axial flow fan assembly which moves the air through the tower and is an integral part of the cooling process as well as a significant contributor to initial and operating costs. Continuing research in fan design has significantly improved effectiveness, with the remaining principal research objective being a cost effective

This paper examines the correlation between structure of aromatic triazoles and the ease of their biodegradation

The decreasing availability of high quality water

Some of the monitoring tools used to determine adequate treatment concentrations and to optimize performance with respect to chemical costs and avoided costs are described

Identifying

has become a must to meet restrictions related to chromate usage

NWD can be used as wet/dry cooling tower by using wet/dry lanes as dry sections which are acting similar to finned tube dry sections

A description of the new technology and case histories demonstrating field efficacy will be presented

temperature

Operational cycling and construction defects can accelerate deterioration

Surface blisters were found on 15% to 20% of the columns in two towers after 18 months of service

Information will be presented on the above issues

This would be the first cleaning of the tower in 20 plus years of operation and two major hydrogen mishaps to the tower
