Adiabatic Flame Temperature - an overview
https://www.sciencedirect.com/topics/engineering/adiabatic-flame-temperature
The adiabatic flame temperature is one that occurs when the combustion chamber is well insulated with no heat losses (adiabatic conditions). The peak adiabatic flame temperature occurs at around Φ = 1 in an ideally insulated combustion chamber. Figure 6.1 is a typical graph of flame temperature for a natural gas–air mixture. As percent combustion air increases, that …
Adiabatic Flame Temperature - an overview
https://www.sciencedirect.com/topics/chemistry/adiabatic-flame-temperature
The adiabatic flame temperature defines the temperature of the products of combustion after all chemical reactions have reached equilibrium and when no heat is allowed to escape (or enter) the combustor. Each fuel has a unique adiabatic flame temperature for a given amount of air.

On the other hand, oxygen enrichment of the air blast increases RAFT, since the volume of gas is the flame is less because of less nitrogen. RAFT should be maintained in between 1900-2100 C.

The adiabatic flame temperature sub model is used for the calculation of the RAFT. It can be derived by means of empiric formulas or very accurately from adiabatic mass and heat balance calculations (Geerdes et al, 2009). The model presented in this work is based on the latter approach. Complete gasification under

Silicon content can also be controlled through blaster furnace operation, a reduction in the raceway adiabatic flame temperature (RAFT) can decrease the reduction rate of SiO 2 to SiO. This same effect can also be achieved through a lower cohesive zone height which decreases the temperature at the tuyere level.
