5 Essential Expertise for Water, Energy and AirSM
Cycle Control
• Med-High Purity water (RO
or DI)
• High Cycles of Contration
(100 cycles, 1% Blowdown)
• Excessive cycles
– Long Holding Times
– More “looks” at the radiate heat
zone
– Breakdown of treatment
chemistry
– Concentration of conteminants
Figure 1 Boiler scale greatly impedes heat
transfer and reduces efficiency

6 Essential Expertise for Water, Energy and AirSM
Cycle Control
• Condenser Leak
– Total Hardness increased from <30 ppb to 170 ppb
– Favorable Power/Hog pricing precluded shutdown
• Increased Treatment to match contamination
– PID Trasar control set point increased form 2.4 to 8 to 5
ppM
• Old “Boiler Conductivity Limit” didn’t apply
• Boiler Quickly brought back into limits
– Consistent treatment in Feedwater
– 30 second Operator test of boiler water
