17-15: Novel Methods to Characterize Cooling Tower Fill Fire Resistance Materials

17-15: Novel Methods to Characterize Cooling Tower Fill Fire Resistance MaterialsASTM #84, Standard Test Method for Surface Burning Characteristics of Building Materials, was adopted as a product test by CTI and has presented inaccuracy in characterizing the risk level of a cooling tower fill in sustaining a fire. The gas burner does not represent a common fire source in a cooling tower and the ceiling horizontal burning does not represent typical cooling tower fill burning behavior. In this paper, we present a series of novel

blowdown rate

During the past several decades

issues are being raised in matters that were previously beyond reproach

It identifies those components that are impacted

Such cooling towers are thin shell structures compared to their geometric proportions

Today's trends are towards developing larger generating stations at each site

definition of "tough" and "easy duties"

energy absorption and energy dissipation is the key characteristic of any structure in dynamic loading

The paper gives the guides lines of the fill design in relation with the fouling and the scaling resistance

That means that a level playing field for axial impeller performance comparisons is absent

The paper will show how significant uncertainty is calculated versus predicted capability in natural draft cooling towers can occur

Can a worker be exposed to with no resultant injury
