THE ROLE OF ADDITIVES IN COMBUSTION MECHANISM OF AMMONIUM NITRATE
SINOPSIS
This paper presents an analysis of the observable combustion behavior of Ammonium Nitrate (AN) mixtures with different additives, fuels, and explosives. On the basis of flame structure investigation by fine tungsten-rhenium thermocouples, it was determined that the surface temperature of AN is controlled by the dissociation reaction of the salt occurring at the surface. Results obtained from experimental analysis have indicated that the leading reaction of combustion of AN doped with additives proceeds in the condensed phase up to pressures of 20−30 MPa. In this paper, a possible reason for the inability of pure AN to burn has been suggested and the role of additives in the combustion mechanism is also discussed.
