【Q&A Question 142】September 09, 2016: What are the principles for adjusting the flame in a heating furnace? The answer key will be available after responding; scoring is based on answering the key points. The flame is pale blue-white in color, clear and bright, well-defined and strong; it does not drift around, does not touch the furnace tubes, and features multiple burners, short flames, and even flame heights. It is strictly prohibited to adjust the flame too long so that it directly hits the furnace tube.
Multiple burners, short flames; the flame is light blue. Fine adjustments should be made to prevent fluctuations in gas pressure. Pay attention to oxygen levels and negative pressure in the furnace chamber
1) Under normal operation, the temperatures in various parts of the furnace remain within the specified range, following the principle of using multiple burners with short flames and uniform combustion； 2) When combustion is normal, the furnace chamber should be bright; the flame should be orange-yellow in color, clear and bright, without being distorted or scattered ； 3) It is strictly prohibited to adjust the flame to be too long and direct it at the furnace tubes.

Short flame, even flame height, no burning of the furnace tubes
No fire loss, strong and powerful, does not damage the furnace tubes
Furnace negative pressure, fuel gas pressure,
