Abstract
A chemical plant may include one or more fired heaters for heating of process streams. A fired heater may include a direct-fired heat exchanger that uses the hot gases of combustion to raise the temperature of a process fluid feed flowing through tubes positioned within the heater. Fired heaters may deliver feed at a predetermined temperature to the next stage of the reaction process or perform reactions such as thermal cracking. Systems and methods are disclosed to optimize the performance of fired heaters or reduce energy consumption of fired heaters.
