Suppression of a Baffle-Stabilized Spray Flame by Halogenated Agents
Anthony P. Hamins, Cary Presser, L Melton
A series of experiments was conducted on baffle-stabilized spray flames in an effort to provide an improved understanding of the influence of various parameters on the processes controlling flame suppression. Measurements were made of the agent mass required to suppress the spray flames as a function of the agent injection duration (which was designed to deliver a constant mass flow of agent to the burner for a controlled duration), the air velocity, the oxidizer temperature, the ambient pressure, and the fuel flow. The agent mass fraction required to extinguish the flame was estimated from the agent mass divided by the agent injection duration. Extinction measurements were performed with the gaseous agents CF3Br, CF3I, C2HF5 (HFC-125), and C3HF7 (HFC-227ea).
