Chemical Effects of CF3H in Extinguishing Counterflow CO/Air/H2 Diffusion Flames.

July 28, 1996
Author(s)
Gregory T. Linteris, G S. Fallon, H K. Chelliah
The relative importance of introducing CF3H as a fire suppressant with the oxidizer or the fuel stream, and its chemical and thermal effects on the extinction condition of counterflow CO/air/H2 diffusion flames, are investigated both experimentally and

Inhibition of Premixed Methane-Air Flames by Fluoromethanes

April 1, 1996
Author(s)
Gregory T. Linteris, L Truett
This paper presents the first calculations and measurements of the burning velocity of premixed hydrocarbon flames inhibited by the three one-carbon fluorinated species CH2F2, CF3H, and CF4. The chemistry of these agents is expected to be similar to that

Inhibition of Flames by Condensed-Phase Agents

March 26, 1996
Author(s)
Gregory T. Linteris, D Reinelt
The ban on the production of the fire suppressant CF3Br has created a need for replacement agents. Obvious alternatives are other halogenated hydrocarbons, and much research has recently been devoted to understanding their relative performance and

Prediction of HF Formation During Suppression (NIST SP 890)

November 1, 1995
Author(s)
Gregory T. Linteris, G. Gmurczyk
The acid gases hydrogen fluoride, hydrogen chloride, and hydrogen bromide (HX, where X denotes a halogen), are thought to be the most damaging and dangerous of the potential decomposition products, and much study has been devoted to determining the amounts

Effect of CF3H and CF3Br on Laminar Diffusion Flames in Normal and Microgravity

October 16, 1995
Author(s)
B. A. VanDerWege, M T. Bush, S Hochgreb, Gregory T. Linteris
Due to the ban on production of bromotrifluoromethane (CF3Br) because of its high ozone destruction potential, there has been recent interest in finding a replacement for it for fire extinguishing applications. While a variety of potential replacements are

Inhibition of Premixed Methane-Air Flames by Halon Alternatives

September 10, 1995
Author(s)
Gregory T. Linteris, L Truett
Halogenated hydrocarbons are effective and widely used as fire suppressants. Because of their suspected destruction of stratospheric ozone, however, the production of these agents, the most popular being halon 1301 (CF3Br), has been discontinued. There

Inhibition of Premixed Methane-Air Flames by Iron Pentacarbonyl

July 31, 1995
Author(s)
Gregory T. Linteris, G. Gmurczyk
Brominated fire suppressants are effective and widely used. Due to their destruction of stratospheric ozone, however, the production of these chemical was halted in January 1994. Although testing and development of possible substitutes is occurring, a

Parametric Study of Hydrogen Fluoride Formation in Suppressed Fires

May 9, 1995
Author(s)
Gregory T. Linteris, G. Gmurczyk
Some of the proposed replacements for CF3Br, the fluorinated hydrocarbons, are required in higher concentrations to extinguish fires and contain more halogen atoms per molecule. Since they decompose in the flame, they produce correspondingly more hydrogen

MODELING OF HYDROGEN FLUORIDE FORMATION FROM FLAME SUPPRESSANTS DURING COMBUSTION

January 1, 1995
Author(s)
Valeri I. Babushok, Donald R. Burgess Jr., Gregory T. Linteris, Wing Tsang, A W. Miziolek
We have completed an initial computational study related to acid gas formation for two of the leading near-term Halon substitutes, FE-13 (CF,H) and HFC-125 (C,F,H), and compared these results with Halon 1301 (CF,Br). Our goal is to determine whether we can

Acid Gas Production in Inhibited Premixed Flames (NISTIR 5499)

September 1, 1994
Author(s)
Gregory T. Linteris, M D. King, A Liu
Halogenated fire extinguishing agents such as CF3Br decompose in flames to form hydrogen halides such as HF and HBr and other toxic and corrosive products. Possible replacements for halon 1301 are required in significantly higher concentrations to

Acid Gas Production in Inhibited Propane-Air Diffusion Flames

August 21, 1994
Author(s)
Gregory T. Linteris
The proposed replacements to halon 1301, mainly fluorinated and chlorinated hydrocarbons, are expected to be required in significantly higher concentrations than CF3Br to extinguish fires. At these higher concentrations the by-products of the inhibited

Acid Gas Production in Inhibited Diffusion Flames

May 3, 1994
Author(s)
Gregory T. Linteris, M D. King, A Liu, C A. Womeldorf, Y. E. Hsin
The proposed replacements to halon 1301, mainly fluorinated and chlorinated hydrocarbons, are expected to be required in significantly higher concentrations than CF3Br to extinguish fires. At these higher concentrations the by-products of the inhibited

Flame Inhibition Chemistry and the Search for Additional Fire Fighting Chemicals (NIST SP 861)

April 1, 1994
Author(s)
Marc R. Nyden, Gregory T. Linteris, Donald R. Burgess Jr., P R. Westemoreland, Wing Tsang, Michael R. Zachariah
Replacements for the current commercial halons should posses a diverse set of properties which are rarely found together in the same molecule. Thus, the ideal candidate for the replacement of halon 1301 would be a nontoxic gas which is reactive in flames

Agent/System Compatibility for Halon 1301 Aviation Replacement

October 20, 1993

Richard G. Gann, E Braun, Thomas G. Cleary, Richard H. Harris Jr., F Horkay, Gregory T. Linteris, G B. McKenna, Marc R. Nyden, Richard D. Peacock, Richard E. Ricker, Mark R. Stoudt, W. K. Waldron
This project has developed measurement methods and provided data for the appraisal of 12 USAF-specified candidate halon 1301 replacements for compatibility with flight systems, people, and the environment. The exposures of metals, elastomers and lubricants
