Heating furnace nozzle adjustment
Thread Content
What are the principles governing the adjustment of the heating furnace nozzles? What is the role of primary and secondary air? Lastly, what is the optimal color of the flame in a heating furnace – orange-red or blue?
The color of the flame in a short flame burner depends on what type of gas you are using
What principles govern the adjustment of the heating furnace nozzles? 1. Do not exceed the temperature limit. 2. The burners should not stop burning. 3. If there are multiple burners, adjust them symmetrically. 4. In cases with two chambers or more, pay attention to maintaining balance when making adjustments
Primary air provides the combustion air, while secondary air is used to adjust the flame shape and control it!
The color of the flame is mainly determined by the burning medium; it usually features a short flame, steady flames, uniform combustion, and no fouling of the furnace tubes!
The flame is short and even, with the burner lighting up symmetrically; the fire does not go out nor does it affect the furnace tubes. The flame is blue when burning gas and yellow when burning oil
Short flame length, even flame shape, symmetric ignition; the primary air is used to supply oxygen for fuel combustion, thereby ensuring complete combustion of the fuel and reducing the amount of carbon black produced. The secondary air supplied through the secondary air duct serves as a supplement and helps to adjust the angle of the flame. Generally, when the gas contains a high proportion of hydrogen, the flame appears light blue in color.
