Ignition of NF3 with Hydrocarbons and Fluorocarbons.
Abstract
The ignition characteristics of NF3 were studied with several hydrocarbons and fluorocarbons at various initial pressures and reactant concentrations. All tests were conducted statically in an instrumented high-pressure reaction vessel with the use of either spark or hot-wire ignition sources. Product gases were analyzed in order to determine combustion efficiency. Ignition delay, over-pressures, and temperature rise were determined for each test. The optimum oxidizer/fuel ratio for the most complete reaction of NF3 was determined for mixtures of NF3 and C2H4; NF3 and 1, 3 -C4H6; NF3 and C5H6; and NF3 and C2H2F2. The feasibility of using N2F4 as an injected additive for firing spontaneously spark-ignitable mixtures of NF3 and C2H4 at concentrations of up to 10% N2F4 in helium was investigated with negative results.
