Optimization of the heating system at Sogn school

Abstract

The heating system of the Sogn school consists of three oil boilers, one electrical boiler and one bio boiler which provide the building with heat. However, the bio boiler is too inefficient. The purpose of this report is to document the different alternatives to increase the efficiency of the bio boiler. The report does not document any results of trials with wood briquettes, because the school had a problem in supplying the necessary wood fuel to operate the bio boiler. In a final recommendation the optimum of the five different improvements will be presented, which basically increase the coefficient of performance and reduce the harmful emissions.
