Abstract

It is shown that DSC curves reveal considerably less energy release than the true reaction heats of the oxidation of organic materials. This fact may be due to the low oxidation rate of some primary volatile products, especially carbon monoxide, inevitably forming during the oxidation of organic and carbonaceous materials at the temperatures of DSC experiments. The measured heat is strongly affected by the experimental conditions and can be brought closer to the net heat of combustion by catalytic oxidation of the carbon monoxide formed inside the measuring cell. The goals of DSC and DTA studies of fuels should be the correct characterization of burning properties and a rough estimation of calorific values belonging to the volatiles and the char formed during burning. In this direction, further research is needed.
