- Abstract
- Several NGP projects studied the mechanisms of chemical suppressants, including those containing halogens, phosphorus, and metals. From the work, several general principles of chemical flame inhibition are outlined. The present paper describes the conditions for which a chemically active agent can be effective, and when it is most effective, and when it may not be effective. These general principles are demonstrated with numerical and experimental data and analyses for flame inhibition by various metals, halogens, phosphorus, and inert compounds, in premixed, counterflow diffusion, and cup-burner flames.
