Numerical Analysis of the Combustion Process in the Wood Stove

Abstract

Today small-scale wood stoves becoming increasingly popular in Poland, and the use of wood logs in small-scale units stoves is expected to increase substantially towards 2020. Many new constructions are created and numerical modelling of combustion processes is an increasingly important stage in the design work of new constructions. The article presents the numerical study of a combustion process in a wood stove. The computational fluid dynamics (CFD) model include fluid flow, chemical combustion reaction, and heat exchange. The simulation was proceeded by experiment with the commercially produced fireplace by company Kratki.pl. The test bench was designed according to PN-EN 13229 codes requirements. The successful verification of results with experiment was a base to perform a series of simulations to achieve the optimal construction with increased efficiency and reduction of the harmful components of combustion.
