Sažetak
The efficiency of heat generators (boilers) of different types commonly used in today’s heating systems is analyzed in this paper. The dependency of the efficiency on load is shown and an analysis of the total efficiency of the heating system is derived. The referent system consists of four heat generators guided by the stage sequencing control. Three different types of heat generators, i.e. standard, low temperature and condensing heat generators have been taken into consideration. The heat generator thermal load, number of heating days (hours) and total thermal load are the most important influential factors that have to be taken in consideration. A numerical example is presented for a case of 2, 4 MW maximum heating load. Comparison of results has been made accompanied by the commentary and final conclusions.
