Corrosion products subsequently deposit in the HP evaporator tubing and form the basis of the under-deposit corrosion damage mechanisms. This link forms the main focus of the cycle chemistry assessments in the plants, which identify the precursors or active processes if left unaddressed, will eventually lead to failure/damage by one or both mechanisms.

Heat pump vacuum evaporators | Condorchem Envitech

The operation of a heat pump vacuum evaporator is based on bringing the effluent to its boiling point, which is around 40 C when working under vacuum conditions. When the effluent begins to boil in the evaporator boiler tank, the steam condenses and is withdrawn from the system as more effluent is fed into the boiler tank.

Boiler Feedwater - an overview | ScienceDirect Topics

Boiler feed water quality is limited owing to problems of (1) scaling, (2) corrosion, and (3) foaming. In order to avoid these problems, the quality guidelines shown in Table IV have been adopted. Data in Table IV show a major difference between cooling water and boiler feed water quality constraints, in that boiler feed water has a strong relationship between water quality and the pressure of

How To Clean Out Scale From A Heat Exchanger | Remove

Heat exchangers allow heat to flow through a material, generally a copper tube or stainless steel plate, from the hot side to the cool side. Scale or any other material that accumulates on the heat exchange surface acts as an insulator and reduces the efficiency of the heat exchanger.
