Characteristics of fans used in low-power boilers

  • Jaroslaw Bartoszewicz Poznan University of Technolog Faculty of Machines and Transport Chair of Thermal Engineering


This paper presents the results of tests conducted in the Chair of Thermal Engineering of Poznan University of Technologydedicated to determining the efficiency of low-power barrel fans, which are used in low-power boilers. Operation parametersof fans produced for industry were checked with respect to the requirements of Directive 2009/125/EC of the EuropeanParliament. The tests were used to determine the efficiency of fans and to compare them against values determined accordingto the European Directive. The test results are presented on graphs as functions of air volume flow. Those characteristicscomprise distributions of total pressure, electric power absorbed by the motor, and fan efficiency. The results indicate thatthere is a need to develop new guidelines. They should concern those efficiencies of low-power fans which are not coveredby Directive 2009/125/EC of the European Parliament.
