What principles does the burner use during its work

The size of the heating power of the burner depends on the strength of the flame (furnace temperature), the surface area of ​​the furnace tube and the size of the total heat transfer coefficient. The stronger the flame, the higher the furnace temperature, the greater the temperature difference between the furnace and the oil flow, the greater the heat transfer; the larger the area of ​​the furnace tube that the flame and flue gas touch, the greater the heat transfer; the heat transfer function of the furnace tube The better, the more correct the furnace structure, the more heat transfer.　　The strength of the flame can be adjusted by controlling the nozzle. But for a furnace with a certain structure, the furnace temperature will no longer rise after reaching a certain value under the premise of normal operation. The total heat transfer coefficient of the furnace tube surface is affirmative for a furnace, so the heating capacity of each furnace has a certain boundary. In the essential application, flame burning discordance and furnace tube coking will affect the heating capacity of the burner. Therefore, we must pay attention to the control of the incinerator to make it incineration, and to prevent the one-sided furnace tube temperature from being too high and coking.　　The liquid (gas) fuel is burned in the radiant chamber (furnace) of the burner, and high-temperature flue gas is generated and used as a heat carrier to flow to the convection chamber and be discharged from the chimney. The crude oil to be heated first enters the furnace tube of the convection chamber of the burner. The temperature of the crude oil is usually 29. The furnace tube focuses on obtaining heat from the flue gas (9) flowing through the convection chamber by convection. This heat is transferred from the outer surface of the furnace tube to the inner surface of the furnace tube by heat transfer, and at the same time, it is conveyed to the crude oil flowing in the tube by convection. . The crude oil enters the radiant chamber tube from the convection chamber furnace tube. In the radiant chamber, the flame emitted by the incinerator focuses on radiating one part of the heat to the exterior surface of the furnace tube, and the other part radiates to the furnace wall where the furnace tube is laid. On the upper side, the furnace wall radiates heat again to the exterior surface of the furnace tube on the side of the fire back surface. The radiant heat of these two parts work together to raise the external surface of the furnace tube and cause a temperature difference with the inner surface of the tube wall. The heat flows to the inner wall of the tube by conduction, and the crude oil flowing in the tube continuously obtains heat from the inner wall of the tube in a convective manner.
