95-02: Partial Collapse and Rebuild of the Conesville Unit 4 Mechanical Draft Cooling Tower Water Blowdown TreatmentOn January 31, 1993, the north side of the No. 4A mechanical draft cooling tower serving Columbus Southern Power's Conesville Unit 4 collapsed; forcing the 800 MW coal fired generating unit out of service. The cause of catastrophic structural failure, tower reconstruction program, and considerations for preventing similar failures in the future will be reviewed.
Higher capital first costs were offset by innovative structural designs that reduced overall installed costs
and characteristics necessitate that in situ generation
The paper presents laboratory data and history in which the effectiveness of a new cost effective treatment for control of calcium carbonate at 200 times calcite saturation at alkaline conditions
This paper will present both field and laboratory test data independently obtained from operating cooling tower water systems that rely solely on PEFDs for microbiological control
The drift from the test cell was determined by isokinetically sampling a representative fraction of the test cell airflow above the drift eliminators
electricity consumption
The amounts of water required for cooling depend on the temperature of the cooling water and the particular use
This paper discusses the origin and the effect of the aerodynamic interference
Proper attention to cooling water systems operating and control parameters
It is practically as simple to use as the present Merkel Theory
The result: scaling and loss of heat exchange capacity in critical processes
This presentation details some of the development problems encountered in obtaining almost 100% conversion of bromide ion to Hypobromite
