Even with diligent chemical feed and monitoring, cooling towers, and especially the tower fill, can accumulate scale and microbiological deposits that inhibit heat exchange, and, in worst case scenarios, may induce partial collapse of the tower. This article examines methods to clean tower fill before fouling causes irreversible damage.
The project includes central plant optimization, chiller replacement, demand response, building automation and controllers.
Sulzer’s Chemtech unit will exhibit its mass transfer solutions and show advanced augmented reality and virtual reality experiences which give participants a closer look at the equipment and how it integrates into industrial plants.
DMCCO manufactures multi-point continuous combustion analyzers for use in particulate-laden gas streams including utility & industrial boilers and lime kilns.
Researchers learned from a deadly 1986 accident and others since then that the reducing environment produced by oxygen scavengers is the prime ingredient for single-phase flow-accelerated corrosion (FAC) of carbon steel.
Water flow in a steam generating power plant may range from the small such as process samples to the very large, i.e., condenser cooling water. Monitoring some of these flows is quite challenging.
Environmental concerns with regard to protection of aquatic creatures at both the intake and outfall of once-through systems have essentially eliminated once-through cooling for modern plants. But this development comes at a time when many of the new combined cycle power plants, and other facilities for that matter, are being staffed by people new to the industry. Fundamental understanding is critical.
Equally important is proper treatment of cooling water for those many plants that still have steam surface condensers and other water-cooled heat exchangers. Scaling, corrosion, and microbiological fouling can cause loss of heat transfer and equipment failure, sometimes resulting in staggering costs to the plant.
The ELG’s for FGD wastewater list two primary methods of treatment.
