Velocity measurements and sampling inside a wood open fire-place to optimize the combustion performances

Wood combustion is one of the main objectives in burning renewable sources. The interest in reducing the environmental impact lead the manufacturers of different wood stoves to optimise the combustion chamber reducing pollutant emission and increasing global efficiency. The aim of this paper is to present how it was possible to optimise the heat exchange inside a wood open fire place using recent Laser Doppler Anemometry equipment. Moreover, samplings of the flue gas was performed in different operation condition and at different delay from the wood charge in order to measure the pollutants emitted and the soot.
