Inhibition Effect and Kinetic Study of Novec-1230 on the Ammonia-Doped Methane Flames

Abstract

Mixing ammonia and methane fuel reduces CO2 emissions while ensuring efficient fire suppression. To ensure the safety of CH4-NH3 in practical applications, efficient fire suppression methods for inhibiting CH4-NH3-air flames should be studied. This research examines Novec-1230’s fire suppression efficiency and reaction kinetics. The results show that Novec-1230 has an excellent inhibitory effect on CH4-NH3-air flames; however, this depends on the ammonia content within the flames. Novec-1230 demonstrates an efficient inhibitory effect on ammonia-rich flames. Fluorine-containing substances influence the fire extinguishing effect, as CF and CF2 interact with H/OH radicals, thereby inhibiting flame combustion. This research aims to understand the potential and effectiveness for Novec-1230 in inhibiting CH4-NH3-air flames, which could improve forecasting and optimization of CH4-NH3 applications, aiming to enhance fire extinguishment efficiency and minimize adverse effects.
