The adiabatic flame temperature is therefore 2310°C. If an estimate can be made of the heat lost from the combustion zone during combustion a non-adiabatic temperature can be calculated which will of course be no better than the estimate made.

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.

A way to characterize the conditions in the raceway is by means of the raceway adiabatic flame temperature or RAFT (Peacey and Davenport, 1979). This adiabatic temperature is a theoretical concept and commonly considered in practice as an empiric parameter for stable blast furnace operation (Geerdes et al, 2009).
