Maximum increase in temperature that can be achieved. This increase only occurs when the substance or reaction mixture decomposes completely and at adiabatic conditions. The adiabatic temperature rise follows from:
DTad = co o -DHr / r o Cp
In case of pure organic substances (Cp Å 2 kJ/kg K) the adiabatic temperature rise is often approximated by DTad = DHr / 2 with -DHr in kJ/kg.
