Abstract
An apparatus for pyrolysis of a sample of a composite material containing a combustible binder includes a combustion chamber configured to receive a sample of the composite material and having an outlet. A heater is associated with the combustion chamber for heating the chamber to a temperature sufficient for pyrolysis of the binder. A blower is in fluid communication with the combustion chamber for creating an airflow through the outlet to remove airborne pyrolysis products from the combustion chamber. An adjustable airflow regulator is operable to adjustably control the airflow to provide a desired minimum residence time within the combustion chamber sufficient for complete pyrolysis of the airborne pyrolysis byproducts.
