Experimental Data Collection for Numerical Model Verification for Wood Stove

Abstract

Ability to perform a simulation with reliable results require experimental verification of the numerical model and simulation methodology. To be able to make verification the test bench was designed and build according to PN-EN 13240 codes requirements with the additional data acquisition system. The bench data collected system consist of exhaust gas analyzer with a probe placed in the chimney which measures CO+, CO₂, O₂, NO, thermal imaging camera which monitors the temperature distribution outside the stove. To be able to monitor the heat distribution inside the combustion chamber the array of 36 thermocouples were placed inside. The data were recorded during entire wood burning cycle according to codes. Tested fireplace insert was the commercial product by company Kratki.pl. 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.
