Clayton Feedwater Treatment Manual

SECTION I

Introduction

This manual outlines the proper water treatment for Clayton steam generators and fluid heaters, as well as the proper operating procedures that would ensure many years of a problem-free machine operation. Proper and adequate feedwater treatment must be used from the time your Clayton steam generator / fluid heater is commissioned. Daily treatment and care of the feedwater supply is the sole responsibility of the user. Since maintaining a properly treated feedwater supply is beyond the control of Clayton Industries, Clayton Industries will NOT be responsible for any equipment damage resulting from improper and inadequate water treatment. Continuous feedwater treatment is required at all times, even during the periods of wet lay-up shutdowns. Water testing must be conducted daily, even during the periods of wet lay-up shutdowns. Instituting a feedwater treatment program and maintaining proper and adequate care of Clayton equipment is the owner’s responsibility. Arrangements for providing continuous feedwater treatment should be made when purchasing a steam generator / fluid heater. Suitable water treatment equipment should be installed before placing the steam generator / fluid heater into service. Furthermore, pay particular attention to offline (lay-up) conditions, since these conditions may be more detrimental than online conditions. If a unit is laid up dry, it must be completely dry with no traces of water. If a unit is laid up wet, it must be completely wet with proper chemical treatment and the heating coil must be absent of all air /air pockets. Also, pay particular attention to the water conditions during start-up and make sure that the proper water conditions are being maintained. During start-up, a substantial amount of cold water is nor- mally added and it may take extra time for the hotwell to stabilize and reach its normal efficiency level.

NOTE It may be necessary to temporarily increase the feed of water treatment chemicals to help recover from start-up conditions. This temporary increase will help bring feedwater parameters (i.e. sulfite level) back into specification quickly.

To ensure proper and adequate water treatment, you are encouraged to take advantage of Clayton's AWARE water treatement program, as well as its Coil Guard Technology. For customers who choose to forgo the AWARE water treatment program, Clayton strongly recommends recording feedwater conditions daily and maintaining long-term records using AWARE data log reports. Finally, a complete understanding of the operation of a Clayton steam generator / fluid heater is very important in its successful operation. Therefore, you are encouraged to thoroughly review the con- tents of the manual.
