Rate of heat release measurements with the Swedish box test

摘要

AbstractThe Swedisn box apparatus was modified to include an oxygen analysis of the exhaust gases to be compared with the conventional exhaust gas temperature measurement. A slow‐burning material shows good correlation between the temperature measurement and the rate of heat release. A fast‐burning material, however, consumes all the available oxygen, and the temperature measurement becomes a measure of only the thermal properties of the mater
