PRIMARY ENERGY SAVINGS USING HEAT STORAGE FOR BIOMASS HEATING SYSTEMS

Abstract

District heating is an efficient way to provide heat to residential, tertiary and ndustrial users. The heat storage unit is an insulated water tank that absorbs urplus heat from the boiler. The stored heat in the heat storage unit makes it ossible to heat even when the boiler is not working, thus increasing the heating fficiency. In order to save primary energy (fuel), the boiler operates on nominal oad every time it is in operation (for the purpose of this research). The aim of his paper is to analyze the water temperature variation in the heat storage, epending on the heat load and the heat storage volume. Heat load is calculated or three reference days, with average daily temperatures from -5 to 5 °C. The rimary energy savings are also calculated for those days in the case of using eat storage in district heating.
