Heating Saturated Air in an Incinerator

  1. Aug 10, 2007 #1
    I need help to understand heating requirement in an incinerator meant for aqueous wastewater;

    The wastewater is evaporated in a primary chamber and then the gases are required to be heated to 1200 deg.C in a secondary chamber with 2 seconds residence time. The operating pressure is just about atmospheric. In calculating the heat input, do I need to consider specific heat of water vapors being raised to a temp. of 1200 deg.C? Is it possible that water vapors in the air will rise to this temperature without being pressurized? Given the 2 seconds residence time, will both air and water vapors reach that temperature together?
