MANUFACTURING PROCESS OF MEMBRANE WALL FOR WATERTUBE BOILER

U diplomskom radu ukratko je opisano područje kotlogradnje, osnove o kotlovskim postrojenjima i proizvodni proces membranskog zida vodocijevnog kotlovskog postrojenja. U prvom dijelu opisan je princip rada parnog kotla, uvjeti eksploatacije i podjele kotlovskih postrojenja. Drugo poglavlje diplomskog rada opisuje komponente kotlovskog postrojenja, materijale koji se primjenjuju i tehnologije koje se primjenjuju u izradi. Navedeni su propisi prema kojima je potrebno provesti izradu kotlovskog postrojenja. U trećem poglavlju na osnovu promatranja unutar proizvodnih pogona tvrtke „Đuro Đaković Termoenergetska postrojenja d.o.o.“ ukratko je opisan tijek izrade membranskog zida. Četvrto poglavlje opisuje primjenu EPP zavarivanja u području kotlogradnje. Opisan je tehnološki proces izrade membranskog panela pomoću EPP zavarivanja kojim se ostvaruje zavareni spoj između cijevi i trake.This paper describes field of steam boiler production, basics about boiler power plants and manufacturing processes for watertube boiler's membrane wall. First chapter describes work principles of steam boiler power plant, conditions of service and examples of boiler types. Second chapter of paper describes main components of boiler power plant, materials that are used for manufacturing, and manufacturing technologies in boiler production. Also there are few words about norms and regulations in boiler production. Third chapter is based on observation of production lines inside of factory „Đuro Đaković Termoenergetska postrojenja d.o.o.“ and it describes production process for a membrane wall. Fourth chapter describes application of FCAW process in boiler production and manufacturing process of membrane panel by using FCAW which is used for welding of tubes and fins. In the last part of this thesis, we have welding technologies explained: both nozzle - header as well as nozzle with header - tubular membrane wall. Procedures are shown in the practical part of this thesis; as well as in all of the mentioned chapters. With every explaination of the theoretical or practical part, sketches and photos that were taken in Đuro Đaković Termoenergetska postrojenja (ĐĐ TEP) workshop are attached. Their purpose is to display some of the terms and activities
