The reference answers will be visible after responding; points are awarded by identifying the key points. (Unless otherwise specified, all questions and answers are based on hydrogenation units.) ) 1. Under normal operation, the temperatures in various parts of the furnace remain within the specified range, following the principles of using multiple burners, short flames, and uniform flame distribution. 2. When combustion is normal, the furnace interior should be bright; the flame should be light blue in color, clear and bright, without being skewed or scattered. 3. It is strictly prohibited to adjust the flame so that it points directly at the furnace tubes or furnace walls.

The principles for adjusting the flame in a heating furnace are as follows: 1) Under normal operation, the temperatures in various parts of the furnace should remain within the specified range, following the principle of using multiple burners, 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 distinct, 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, bright furnace interior
Satisfactory answer: 1) When operating normally, 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 distinct, 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.
The flame is light 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 points directly at the furnace tube.
Multiple burners, short flames, even flame distribution, bright flames, no black smoke from the chimney, flames do not drift
1) When operating normally, 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 is bright; the flame is orange-yellow in color, clear and bright, without being distorted or scattered ； 3) It is strictly prohibited to allow the flame to be adjusted to an excessive length and directly hit the furnace tubes.
