Abstrakt

Insight into the behaviour of flame characteristics in wood fires is required for developing rules for dimensioning the combustion spaces in woodburning stoves. This study presents a simple model by which it is possible to obtain the temperatures, velocities and mass flows in fires. These characteristics could serve as a basis for evaluating heat transfer from flames to different surfaces in a stove. They could also be used in problems concerning fire spread. Results are presented showing the variation of flame characteristics with different parameters of interest in wood fires.
Since in literature no experimental results were available on the small wood fires that are of interest in the present work, a series of experiments were performed to determine flame heights. The experimental results agree with the estimates derived from the model, for an excess air factor of just 1.5-2.5.
