Abstract:

This test program studies the burning characteristics of titanium under air flow conditions. The flat plate titanium samples are ignited by molten titanium from an electrically heated ignitor. Air flow conditions that support sustained combustion of a single sample are determined. The burn rate is measured on all tests with steady state burning. Argon gas is shown to be a feasible extinguishing agent for a titanium fire. Quick injection of a sufficient amount of argon gas to maintain a 60 concentration by volume of argon results in quick suppression by oxygen depletion. Carbon dioxide CO2, a common fire extinguishing agent, is shown to sustain titanium burning at an accelerated rate. The ultraviolet UV radiation emitted by burning titanium is shown to be of a sufficient intensity for existing UV fire detectors to detect at reasonable distances.
