Abstract : The mechanism of the inhibition of hydrocarbonair flames by alkali-metal salts was investigated. The approach to this problem involves study of the combustion of simple hydrocarbons such as methane to which known concentrations of alkali-metal salts or the metals themselves in the vapor state have been added. An apparatus was constructed permitting the preheating of methane plus various additives to 500 C, with subsequent combustion as either a laminar premixed flame or laminar diffusion flame. Preliminary experiments were perfor ed with flames involving CH $, H, air, O, NaNH2, elemental Na, and elemental K. Definitive experiments have not yet been carried out. (Author)
