Abstract: According to the characteristics of petrochemical flame heating furnace, this paper, taking the new 112 MW single

gas-fired square box furnace as the research object, quantitatively and qualitatively analyzedthe main factors affecting the efficiency

of the furnace, respectivelyanalyzed and discussed the influence of latent heat of flue gas, sensible heat ratio of flue gas, formation

mechanism of cold condensation in the interwall heat exchanger and its influence on the waste heat recovery system, heat dissipation

rate of the hot surface of the furnace body, and the influence of incomplete combustion/nitrogen oxides,summarized the economic

exhaust temperature and efficiency, provided several reference index scope and finally introduced several typical inter-wall air

preheaters.
