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 ...

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 ...

Stacking is the abnormal accumulation of refrigerant in the condenser of a chiller. It is commonly caused by a decrease in the difference in pressure or lift between the condenser and the evaporator.

Part 1 of this series discussed the importance of steam condensation in conventional power units and the heat recovery steam generators (HRSGs) of combined cycle plants. Condenser tube waterside ...

The upper left portion of the diagram shows the exhaust steam entering the air cooled condenser: •Steam In: The total mass flow rate of the exhaust steam. It depends on the plant size and steam cycle ...

In Part 2 of this series, we examined how both water-side microbiological fouling and mineral scaling will seriously degrade condenser heat transfer, and how an accurate monitoring program will detect ...
