PLANT DESIGN: Powre Plant Cycles with Multiple Direct Contact Heaters

摘要

The regenerative feedwater cycle of modern fossil and nuclear power plants normally includes four or five low-pressure, closed (tube surface-type) feedwater heaters (CFWHs). However, maximum efficiency can be obtained when CFWHs in the power plant cycle are replaced by direct contact heaters (DCHs). Advancements in steam injector technology, such as Fisonic devices, have helped make DCHs an attractive option.
