93-07: Simultaneous Comparison of the CTI HBIK and the EPA Method 13A Vibration

93-07: Simultaneous Comparison of the CTI HBIK and the EPA Method 13A VibrationCooling tower drift is defined as the percent of circulating water flow that exits from the cooling tower fan stack in the form of fine water droplets and aerosols entrained in the exhaust air. For cooling tower drift tests, the CTI recommended heated Bead Isokinetic (HBIK) procedure is the most commonly used procedure and is close to being accepted as a code by CTI, whereas regulators prefer the EPA Method 13A procedure. In theory both procedures (if

A new method of comparison for existing cooling tower fills has been developed and the performance of the best packing has been expressed in relation to the ideal packing

means of controlling fan power can offer large energy savings for cooling tower owners/operators

Non-Phosphorous programs for mild steel corrosion control in cooling system are often challenged by deteriorated performance

This may result in the failure of heat exchangers and consequently loss of production and costly replacement

This presents opportunities for scale prevention in heat exchangers by using ultrasound

While the number of cases remains marginal (~2 per year)

it has turned out that it is possible to reduce the sound power level of cooling fans with 3 to 8 dBA by the extreme application of more or less known effective principles like wider blade cord and swept leading edge line

nearly seven years later

such as nearby buildings and it is difficult to predict plume condensation behavior either experimentally or analytically

the LSI is zero

and safety of liquid cooling towers

CTI has adopted the elliptical pitot for all pitot-based water flow measurements
