67-03: Fiberglass Reinforced Plastics and Cooling Towers Iron Rot AttackFiber glass reinforced (FGR) thermoset polyester plastics are characterized by very high strength to weight ratios, high heat distortion temperature and dimensional stability, very low water absorption, and immunity to rot and decay. These properties and a record of many years of satisfactory service in applications such as boat hulls and architectural panels, suggest consideration of this construction material, particularly the fire retardant grades,
This paper will present current laboratory and field fouling evaluation methods
They were designed to function with untreated raw water as make-up
Entering a fan cell or removing a stack section with the fan rotating is an OSHA violation
Unique designs will be discussed including: low noise applications
two field case studies will be presented
All three units are served by cooling towers to cool and clean the inlet air to the gas turbine compressors in order to maintain maximum efficiency and capabilities of the units
Various solutions including the high velocity designs and the Kimre drift eliminator are analyzed for cost effectiveness
and Chlorine Dioxide are very strong oxidants and as such are actively depleted by things like UV from sunlight
The paper concludes with guidelines for fouling and scaling control
Results suggest that differences in retention are related to chemical properties of the drift rather than physical lodging of the particle residue
system make-up
The process loop produces steam under vacuum in conditions typically utilized in power or other process plant applications
