Abstract

V diplomskem delu je predstavljena eksperimentalno — numerična analiza zgorevanja kapljevitega goriva KOEL v mali kurilni napravi. Za izvedbo eksperimentalnih meritev je bil uporabljen oljni gorilnik, kapljevito gorivo KOEL, eksperimentalni kotel laboratorijske izvedbe in analizator dimnih plinov. Na podlagi rezultatov meritev emisij dimnih plinov je bil določen optimalni razmernik zraka. S pomočjo računalniške dinamike tekočin smo izdelali numerično simulacijo zgorevanja KOEL za optimalni razmernik zraka in srednjo moč oljnega gorilnika ter predstavili tokovne razmere, temperaturna in hitrostna polja, polja porabe zraka (kisika) pri zgorevanju in polja nastanka produktov zgorevanja.

Secondary title: Experimental - numerical analysis of oil combustion in a small burning device
Secondary abstract: This study focuses on the experimental and numerical analysis of the combustion of the liquid fuel KOEL in a small burning device. For the performance of experimental measurements were used an oil burner, the liquid fuel KOEL, an experimental laboratory boiler, and a flue gas analyser. On the basis of measurements of flue gas emissions an optimal air-fuel ratio was defined. By means of computational fluid dynamics (CFD) we created a CFD numerical simulation of KOEL for the optimal air-fuel ratio and the middle force of the oil burner, and presented flow conditions, temperature and velocity fields, fields of air (oxygen) consumption during combustion as well as fields of the resulting combustion products.
