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 ...

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 steam condenser of a power plant boiler is a critical heat exchanger in the process. Poor performance due to restricted heat transfer can have a dramatic influence on unit efficiency. And, ...

There’s a relatively easy way to make a steam plant more efficient and reliable: keep the tubes of its condenser(s) clean. According to George Saxon, Jr., VP of international sales and marketing for ...
