Abstract
Zadatak ovog diplomskog rada je napraviti analizu utjecaja spusnih cjevovoda na konstrukciju zavješenja parnog kotla. Pod konstrukciju zavješenja parnog kotla spadaju nosivi i potporni profili, ukrute, vješalice i bočni membranski zid. Prvo se obradio teorijski uvod u kojem je objašnjen smještaj i uloga parnog kotla unutar teorijskog procesa termoenergetskog postrojenja, potom je izvršena klasifikacija s obzirom na korišteno gorivo i s obzirom na način cirkulacije radnog medija. Za kraj teorijskog dijela navedeni su glavni dijelovi parnog kotla i sustava koji omogućuje normalno funkcioniranje postrojenja. Nakon aproksimacije membranskog zida parnog kotla korištenjem ekvivalentne ortotropne ploče koja ima jednaka elastična svojstva kao stvarni membranski zid, izvršeno je modeliranje parnog kotla unutar programskog paketa Abaqus/CAE 6.16-1. Na modelu su definirani rubni uvjeti i opterećenja, a zatim je pokrenut proračun u dva slučaja opterećenja. Prvi slučaj je pri djelovanju pretlaka, a drugi pod djelovanjem podtlaka. Analiza se odvija u dva smjera. Prvi je numeričko – analitička analiza koja se koristila pri provjeravanju zavara između vješalica i traka membranskog zida, te pri provjeri kritičnog presjeka vješalice. Isti tip analize izvršen je kod provjere naprezanja cijevi membranskog zida uzrokovana opterećenjem spusnih cjevovoda. Drugi smjer je vizualni prikaz numeričkih rezultata raspodjele naprezanja nosivih i potpornih profila, te ukruta.
Abstract (english)
The task in this paper is to analyze the influence of downcomers on the suspensions structure of steam boiler. Under suspension structure are considered parts as supporting profiles, backstays, hooks and side membrane wall. In first two chapters, theoretical introduction has been done, in which the role of steam boiler in thermal plants theoretical process is explained. Also, considering to fuel that is used and working fluid circulation type, a classification has been made. Main components are described in ending of theoretical part. After aproximation of steam boiler membrane wall by using equivalent orthotropic plate, which has equal elastic properties as membrane wall in real case, steam boiler geometry is made with software package Abaqus/CAE 6.16-1. In same software, boundary conditions and loads on created geometry are defined, whereupon calculation is started. Calculation has been run in two cases, first one is under influence of overpressure and second one, under influence of underpressure. Analysis has been done in two approaches. First, numerical-analytical analysis used for checking of welds between fins and hooks and checking of critical section of hooks. Same type of analysis is used for checking stresses within tubes of membrane wall caused by downcomers influence. Second approach is visual review of stress distribution of supporting profiles and backstays.
