Variable frequency drives (VFDs), also known as variable speed drives (VSDs), are used to modulate the speed of motors in various applications, from hydronic water pumping to VAV fan units to vacuum ...

Over time, condenser coils often become plugged or fouled with dirt, grease, weeds, cottonwood fuzz, or simply layers of dust. These conditions will cause poor airflow through the condenser, which ...

This may not sound like much, but such improvement can be very valuable. In this first part of a two-part series, we will examine basic ideas behind the importance of condenser heat transfer, and in ...

A conventional coal-fired plant in central Arkansas has two 850-MW units. The two units are identical and use identical cooling towers and condensers. The hyperbolic cooling towers are rated at ...

Keeping a power plant’s surface condenser in proper working order requires paying attention to balance-of-plant systems as well. Failure to monitor and maintain cooling towers and vacuum pumps in ...

Condensers are one part of the power plant where the technology is well defined and the benefits of keeping a clean condenser are easily determined. Condenser maintenance is a "pay me now or pay me ...
