The Characteristics of Self-Sustained Particulate Boron Combustion in Air at Ambient Pressure
Abstract
A one-dimensional analytical model for the steady state combustion of a multiparticle cloud of boron in air was established. This model stressed the importance of radiant heat transfer from the luminous flame and heat of combustion from burning particles adhering to the combustor walls to heat the suspended particles to ignition temperature. A steady state, self-sustained flame of elemental boron in air was investigated to verify the model. Trona amorphous boron powder, with nominal particle size of one micrometer, was used as the fuel. Experimental combustion characteristics calculated from the analysis yielded an Arrhenius activation energy near 40 Kcal/mole.
