Abstract
U radu su prikazani čimbenici kvalitete vode brodskih generatora pare te su opisane metode analize i obrade vode brodskih generatora pare koje se koriste kako bi se izbjegli pogonski problemi, poput taloženja kamenca, korozije i odnošenja kapljica vode s parom. Istaknuta je svrha kontroliranja te su navedene granične vrijednosti sljedećih čimbenika kvalitete: tvrdoće, slobodnog kisika, silicija, fosfatnih i kloridnih iona te pH vrijednosti, za napojnu vodu i vodu unutar brodskih generatora pare. Posebna pozornost posvećena je testovima uzimanja uzorka vode koji se koriste kako bi se saznala trenutna koncentracija određene karakteristike u vodi brodskih generatora pare kao i metodama suzbijanja taloženja kamenca i korozije kod brodskih generatora pare. Metode suzbijanja taloženja kamenca u brodskim generatorima pare podrazumijevaju kombinaciju vanjskih i unutarnjih (kemijskih) tretmana, od kojih su posebno istaknute metode kontroliranja karbonata, fosfata i svih polimera. S druge strane, od metoda suzbijanja korozije kod brodskih generatora pare posebno su obrađene sljedeće metode: fizičko otklanjanje kisika, otplinjavanje, kemijsko suzbijanje kisika, kontroliranje pH vrijednosti vode i suzbijanje korozije kondenzata korištenjem neutralizirajućih amina. Zaključno, ukazuje se na mogućnost kombiniranja navedenih metoda s nekim suvremenijim metodama poput metode otkrivanja korozije uporabom svjetlovodne tehnologije te na nužnost kontinuiranog djelovanja svih subjekata pomorskog prometa u pogledu poboljšanja kvalitete vode brodskih generatora pare.
Abstract (english)
This paper shows factors of water quality in steam generators and describes its methods of analysis and treatment of water which is used to avoid operating failure, like a deposit of scale, corrosion and carry-over. The emphasise is on purpose of controlling and limiting values of water quality factors like: hardness, dissolved oxygen, silica, phospate and chloride ions and pH value of boiler and feedwater of steam generators. Special attention is dedicated to testing methods which are used to find out actual concentration of specific features in water of steam generators and its control methods for scale deposition and corrosion. Scale control in steam generators imply combination of external and internal (chemical) treatment of which are specifically stated: carbonate cycle contol, phospate control and all polymer control cycle. On the other hand, corrosion control in steam generators specially focuses on: physical oxygen removal, deaeration, chemical oxygen removal, pH control and control of condensate line corrosion with neutralising amines. In the end, it points to the possibility to combine listed methods with some contemporary methods like finding corrosion using optical fiber tehnology and necessity of continuous actions of all subjects in maritime transport in view to improve quality of water in steam generators.
