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.

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 ...

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, ...

An integral process for utility steam generating systems, including the heat recovery steam generators (HRSGs) of combined cycle power plants, is condensation of the turbine exhaust steam for return ...

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 ...

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 ...
