Superadiabatic heating in combustion chromium in nitrogen

  • Published:
Combustion, Explosion and Shock Waves Aims and scope

Abstract

Combustion of chromium powder in SHS reactors is examined. It is shown that the maximum temperature in the central part of the powder samples is higher than the adiabatic temperature. The observed phenomenon is due to the non-one-dimensionality of the combustion front. Overheating of the central part leads to melting of the product and a decrease in the degree of conversion, which should be taken into account in nitration of samples of large diameter.
