Abstract
U ovom radu analiziraju se kvarovi na brodskom generatoru pare, koji predstavlja složeni izmjenjivač topline u kojem se izgaranjem goriva dobiva potrebna toplina za pretvorbu vode u paru koja se potom koristi za različite brodske namjene. U svrhu pravilnog izgaranja goriva potrebno je nadgledati proces. Problemi koji su uzrok nepravilnog izgaranja vezani su uz kvarove na elementima u sustavima zraka i goriva te loše pripremljeno gorivo. Dijagnosticiranje nepravilnog izgaranja provodi se nadgledanjem plamena u ložištu i boje dimnih plinova, te korištenjem raznih instrumenata poput indikatora gustoće dimnih plinova. Nadalje, navedene su indikacije s mogućim uzrocima kvara, te korektivni postupci tijekom neobičnih pojava u parnom bubnju, visoke i niske temperature pregrijane pare, te propuštanja cijevi. Indikacije opasnih pojava poput požara i eksplozije važno je uočiti na vrijeme kako bi se izbjegla ranjavanje ili smrt pogonskog osoblja. Kako bismo smanjili mogućnost pojave kvarova, potrebno je izvršavati održavanje i redovitu inspekciju. Zaštita generatora pare omogućuje zatvaranje ventila za dovod goriva do gorionika u slučajevima pojedinih kvarova i kritičnih vrijednosti parametara.
Abstract (english)
This paper analyzes breakdowns on a ship steam boiler, which represent a complex heat exchanger in which combustion of fuel obtains the necessary heat for converting water into steam, which is then used for different marine purposes. For the purpose of proper fuel combustion, it is necessary to monitor the process. The problems caused by improper combustion are related to air and fuel damages and poorly prepared fuel. Diagnosis of improper combustion is carried out by monitoring the flame in the combustion chamber and smoke flue dyes and by using various instruments such as the smoke flue gas indicator. Further, there are indications of possible causes of failure and corrective actions during unusual occurrences in the steam drum, high and low temperature of overheated steam, and pipe leakage. Indications of dangerous occurrences such as fires and explosions are important to notice in time to avoid injuries or deaths of the personnel. In order to reduce the possibility of malfunction, maintenance and regular monitoring must be performed. The protection of the steam boiler allows the closing of the fuel supply valve to the burner in case of individual faults and critical parameters.
