Distribucija pare v proizvodnem obratu

Orehek, Uroš (author), Senegačnik, Andrej (mentor)

V diplomskem delu je predstavljena splošna metoda izračunavanja hidravličnih mrež. Matematični model je uporabljen na primeru distribucijske mreže nasičene vodne pare. Obravnavana je realna distribucijska mreža industrijskega obrata s skupnim pretokom nasičene pare 11500 kg h-1 pri tlaku 9,5 bar. Z meritvami temperatur in tlakov po mreži smo ugotavljali dejansko stanje mreže. Dejansko stanje smo primerjali z računskim stanjem. Ugotavljali smo ustreznost posameznih vej in odsekov ter predlagali izboljšave.

• Title: Distribution of steam in the production facility

Abstract

This thesis deals with the basic method of calculating hydraulic grids. The mathematical model is demonstrated on a real world distribution grid of saturated steam in a production plant with a total flow of 11500 kg h-1 of steam, at the head of 9.5 bar. Temperature and head measurements were taken in order to determine the actual state of the grid. We then compared the results of measurements with our calculations, to determine the suitability of singular branches and sections; and to recommend possible improvements.
