If outlet and inlet temperature is at 25 degree Celsius then total heat transfer is heat of reaction which is calculated from heat of formation. But if water is condensed then it releases some amount of heat. So on that basis total heat is calculated. Heat released is negative and heat absorb is positive. Adiabatic flame temperature is temperature of product when no amount of heat is transferring from reactor.
