Fired Heaters with Steam Generation and Air Preheat

Figure 3300-3 shows the stack temperature, after a steam generating economizer, being reduced from 700°F to 300°F while heating the combustion air from 60°F to 600°F. Fired Heater efficiency is improved from 79.7% to 89.3%. This is an example of utilizing both an economizer and an air preheater on a fired heater to optimize the amount of energy recovered by making steam and preheating combustion air.
