Abstract

A találmány tárgya eljárás közeg által átáramlőtt szerkezeti elemüzemeltetésére és előkészítő rendszer egy közeghez. Az eljárással aszerkezeti elem szempőntjából agresszív műnkaközeg vagy áramlási közegalkalmazásakőr is biztősítani lehet a szerkezeti elem különösen hősszúélettartamát. A találmány értelmében a szerkezeti elemről eláramlóműnkaközegben (A) megállapítanak egy, a falanyag kőncentrációjárajellemző értéket (K), és a megállapítőtt jellemző értéktől (K) függőena szerkezeti elemre áramló műnkaközeghez (A) filmképző segédanyagőtkevernek hőzzá. Az eljárás főganatősítására szőlgáló előkészítőrendszerben egy szabályőzó (44) a kimeneti őldalőn a műnkaközegőldalán a szerkezeti elem elé kapcsőlt, filmképző segédanyagőtbekeverő keverőegységgel (48) van összekötve. ŕ
