Does anyone with experience know the startup procedure for ammonia oxidation furnaces?

:) Could any experienced colleague tell me about the startup procedure for the ammonia oxidation furnace?
Hydrogen is generally used for ignition. The hydrogen ignition system in ammonia oxidation furnaces consists of two pipelines: one for ignition and the other for burning, which can also be referred to as the small hydrogen pipe and the large hydrogen pipe. First, turn on the small hydrogen tube and ignite it using a lighter; then rotate the large hydrogen tube while supplying hydrogen to it. When the large hydrogen tube is near the small hydrogen tube, ignition will occur. After that, cut off the hydrogen supply to the small hydrogen tube, and adjust the hydrogen supply to the large hydrogen tube according to the actual situation.
What was said upstairs refers to the ignition method using pressure; for normal-pressure ignition, an alcohol wick is generally used to ignite the mixture of ammonia and air, which is then introduced into the oxidation furnace
