Analysis of the energy and exergy in Munzur University heating system

Two of the main reasons of the increasing consumption of energy are population and income growth. It is predicted that increasing population is going to effect seriously the increase in demand of energy all around the world. According to committed scenarioes, fossil fuels keep continue to remain as a first fuel but ıt is going to lose power until 2040. Crucial environmental problems come to exist because much-used essential energy sources are fossil fuels. This problems bring debates with itself, such as productivity and economy in usage of energy, and usage of energy sources. In light of this informations, usage of energy productively come into prominence. Consumption of energy must be minimise in the houses without losing of life standarts and service quality. Scientific studies of productivity analysis about thermal systems take an important place. First and second rule of thermodynamic is used in the analysis of the thermal systems. The method of analysis based on that rules is called exergy. Analysis of energy and exergy in heating systems take an important place because nearly %25 percent of energy consumption is used for heating houses. In this study, Heating system of Munzur University which spend 500 ton special oil fuel and has 3 heating boilers, 11 heat exchangers, is analysed from the point of energy and exegy. Firstly, combustion in the heating boilers are examined in this study. Effects of the excess air coefficient and flue temperature in combustion on energy and exergy effiency are searched. According to analyse results, heating boilers' energy efficiency is %90 and heating boilers' exergy efficiency is %19.3. As a result, system ecominize nearly %1.5-2 percent fuel in a year if access air coefficient and flue temperatures are enhanced. This rate will be increase if all improvements (such as roof insulation, buildings' thermal insulation for Tunceli should be 7 cm) are done.
