Efficiency and management of gas boilers in public buildings in Vojvodina
Abstract
This paper presents a case study of gas boilers at 14 locations in Autonomous Province of Vojvodina, Republic of Serbia. AP Vojvodina is mainly gasified, i.e. 38 out of 45 municipalities have possibility to use gas. Therefore, a lot of public buildings, such as schools, kindergartens, municipality objects, are heated using natural gas. The aim of this paper is to get a better insight and manners of management of gas boilers in AP Vojvodina. Here are presented results of measuring boilers efficiencies and other parameters and some conclusions are stated. General conclusion is that the gas boilers are poorly managed. The boilers are mostly conventional type; often are oversized; there is a lack of automatic control of boiler according to the outside air temperature; manual control of boilers prevailes; lack of knowledge and failure of measuring instruments lead to significant energy losses. For the most of the investigated gas boilers NOx and CO concentrations are higher than prescribed by regulation.
