In a steam generator, a dry steam of (14 bar) enters the superheater which increase the steam temperature by (65 °C) and reduce the flue gases temperature by (100 °C). Calculate the flue gases mass flow rate per (1 kg/s) of steam flow rate, if the specific heat capacity of the flue gases is (1.005 kj/kg.K).
