Why do the furnace tubes on the outer surface of the fractional distillation heater turn white after being in use for a long time?
In most cases, it is caused by dirt on the surface of the furnace tubes, with a thickness of about 1 to 2 millimeters. This phenomenon becomes more apparent when fuel oil is used as fuel. Cleaning the furnace tubes during downtime helps save fuel and improve thermal efficiency
The inorganic substances formed upon the combustion of impurities in the fuel adhere to the surface of the furnace tubes, causing the surface to turn white
Excess oxygen content in the furnace causes oxidative peeling
