Abstract

Tema završnog rada je ˝Energijsko-eksergijski proračun peći na pelete˝, što znači da je u završnom radu prikazan kompletan energijsko-eksergijski proračun peći izvedene kao protusmjerni i istosmjernirekuperator. Na početku rada je prikazan proračun izgaranja peleta i određen sastav dimnih plinova. Glavni cilj rada je izračunavanje visine peći toplinskog učinka 40kW u protusmjernoj izvedbi te za istu geometriju peći provedena je energijsko i eksergijska analiza istosmjerne izvedbe. Za peć u istosmjernoj izvedbi prikazan je izračun masenog protoka dimnih plinova i izlazne temperature istih za isti toplinski učinak peći. U oba slučaja provedena je eksergijska analiza i određena eksrgijska destrukcija. Dobiveni rezultatisu uspoređeni i izvedeni određeni zaključci.

Abstract (english)

The subject of the final paper is the " Energy-exergy calculation of the pellet stove", which means that a complete energy-exergy analysis of the pellet stove is presented for both cases of the stove as counter and parallel-flowheat exchanger. At the beginning of the paper the analysis of the combustion of pellets is given together with the flue gas composition. The aim of the paper is to calculate the height of the stove with the heat flow rate of 40 kW for the counter-flow heat exchanger and to perform the same calculation for theenergy-exergy analysisof parallel-flow design with the samestove geometry. Calculation of mass flow and exit temperature of flue gas is given for the parallel flow designed stove with the same heat flow rate as in first case. In the both cases theexergy analysis is conducted and the exergy destruction is determined. Conclusions are given on the basis of obtained results.
