A Microscale Combustion Calorimeter

Abstract

A method for measuring the heat release rate of milligram-sized samples is described in this report. Pyrolysis-combustion flow calorimetry (PCFC) separately reproduces the solid-state and gas phase processes of flaming combustion in a nonflaming test by rapid controlled pyrolysis of the sample in an inert gas stream followed by high-temperature oxidation (combustion) of the pyrolyzate in excess oxygen. The rate at which the sample releases its heat of combustion is calculated from the oxygen consumption history. The heat of combustion is obtained from the time integral of the heat release rate.
