Impact of Pellet Raw Material on the Energy and Environmental Characteristic of Low Power Domestic Stoves

  • The results of experimental tests for determine thermal and environmental characteristics of low power pellet stove (8.5 kW) for combustion of wood pellets used for household heating are presented in this paper. Test procedure as well as design and manufacturing of test installation were carried out in accordance with the requirements of the applicable European regulation EN 14785 for ovens of this type. Test installation was designed and assembled in the Laboratory for Fuel and Combustion at the University of Belgrade, Faculty of Mechanical Engineering. Tests were conducted for three thermal loads of the stove (minimum, medium and maximum) and three types of test fuel. Used test fuels were produced from beech wood, fir wood and their mixture, which allowed determining impact of pellet raw material on combustion process. Recalculation of test results in accordance with the requirements of a standard provided determination of energy and environmental characteristics of the tested stove and its classification according to the criteria defined by standard EN 14785.
