17-20: A Fresh Perspective on Controlling Yellow Metal Corrosion Cooling Tower Water ChemistryCurrent methodologies for using azoles to control yellow metal corrosion have existed for years with little advancement. Although these strategies have met corrosion rate requirements for a majority of industrial systems, there are still many failures due to corrosion of yellow metals. This paper will highlight some mechanisms of yellow metal corrosion, new data on the effects of halogens on azoles and a new control strategy.
Additional practical benefits observed in commercial applications include reduction/elimination of proprietary biocides and biodispersants
longer periods of run time and reduce under-deposit corrosion
the frequency of fan air flow testing to verify new or existing fan performances in cooling towers and air-cooled heat exchangers has increased
Samples of fasteners and weldments of corrosion resistant metals and sheets for plastics have been placed in different zones of cooling tower and tested in the laboratory after several years of exposure
and "vibration" will apply to induced motion in mechanical components
resonant frequency concerns and other important parameters
and service standards based on key performance indicators
This paper reviews five problem solving techniques in order to solve the following problem: "Why are copper corrosion rates as measured by coupon so high in recirculating cooling waters
Oil contamination represents a major problem to many large industrial cooling water systems
Many cooling towers in place today operate below their maximum capability due to a number of factors
the price of carbon fiber permits competitive pricing for driveshafts of composite materials
there is a great need to specify a cooling tower to optimize the system
