METHOD OF CLEANING AN EVAPORATOR

摘要

A method of cleaning an evaporator that includes at least one heat transfer element for the evaporation of water, comprising forming a sacrificial layer of a first material on a surface of the heat transfer element (1 ); evaporating water that includes a second material to deposit the second material on top of the sacrificial layer (2, 3); and cleaning the evaporator by removing both the sacrificial layer formed on the heat transfer element and the second layer formed on top of the sacrificial layer; wherein the first material is more easily removed from the heat transfer element than the second material (4).
