Abstract
The present invention relates to a method for preventing the deposition of contaminants in steam systems. In a method of this type, deposits are prevented in a simple and economic manner by metering an additive into the steam, which additive adheres to the steam-side surface of the steam system and has the effect of repelling moisture and contaminants.
