Abstract
Combustion of methanol is being used widely and the chemistry in the process is therefore important to know. When being mixed with formaldehyde and combusted previous measurements with the heat flux method have shown results not consistent with the theoretical models present today. These experiments are in this paper being repeated. A statistical examination of the burners used for the measurements is also conducted. The results are a calibration of the burners and values of the laminar burning velocity that are consistent with the previous values. This calibration is used on the methanol formaldehyde mixtures and gives a result that, as previous results also do, differs from the model. Large scatter is observed in the temperature... (More)

Large scatter is observed in the temperature distribution as measured by the thermocouples. The experimental values consist of some outliers and this can be the result by water contamination. This conclusion is verified by a density determination of the methanol formaldehyde mixtures. (Less)
