Abstract

The design of high pressure oxygen systems requires a better understanding of the combustion properties of structural metals and aIloys to make proper choices for any particular set of operating conditions. Upward combustion of 316 stainless steel (SS) rods is discussed and a combustion model is presented. The effects of varying oxygen pressure and rod diameter on the rate limiting processes for combustion of 316 SS are evaluated. The rate limiting steps for combustion up 316 SS rods are shown to be dependent on incorporation and mass transport of oxygen in the molten mass, and heat transfer between the molten mass and rod. Both these rate limiting steps are shown to be dependent on rod diameter. Small (d^r = 0.051 cm) 316 SS rods are shown to be dependent on convective heat transfer and larger rods (d^r ⩾ 0.32 cm) are shown to be dependent on oxygen incorporation and mass transport in the molten mass.
