3. (20) Fire Heater Specification After the reactor feed leaves the heat exchanger, it enters a fire heater. In this unit the stream is further heated from 215°C to 350°C, which requires 4649 kJ/h of heat to be added. To accomplish this, the heat from the combustion of methane gas is used: CH4(2) +2 02(g) → CO2() + 2 H20(2) $ = 10.0 molh The design of this fire heater indicates that the temperature of the flue gas will not...
