Information

The "three doors and one plate" of petrochemical heating furnaces refer to the throttle (including fuel gas), steam valve, air damper and flue baffle. The opening of the flue baffle and air door of the petrochemical heating furnace affects the flue gas flow in the furnace and the suction force in the furnace. The opening is large, the suction is large, the heat is taken away, the loss is large, and the efficiency is low. At the same time, the amount of excess air is large, and the excessive air enters the furnace, causing the phenomenon of oxidation and peeling of the furnace tube, shortening the service life of the furnace tube; the baffle opening is too large Small, incomplete combustion, smoke appears in the furnace, and even positive pressure backfire. If the damper is opened too small, the amount of air entering the furnace is reduced, the flame is soft and evacuated, the combustion is insufficient, the flue gas contains more carbon monoxide, the fuel consumption is large, and the furnace thermal efficiency is low.

Therefore, in actual operation, the damper and flue baffle of the petrochemical heating furnace should be closely coordinated and adjusted to ensure a certain suction force, control a certain excess air coefficient, improve thermal efficiency, and extend the service life of the petrochemical heating furnace tube.
