Fill-in-the-blank: Acetylene is a flammable and explosive gas; when mixed with air in a certain range, it will undergo ( ). Therefore, before adding material, it is necessary to use nitrogen to remove the air and acetylene gas from the storage tank, reducing the oxygen content to below ( ), before feeding can begin. Answer: Blast zha 3%
Acetylene is a flammable and explosive gas; when mixed with air in certain proportions, it can cause explosion and combustion. Therefore, before feeding, the air and acetylene gas in the hopper must be removed using nitrogen, so that the oxygen content is reduced to below 3%, before feeding can begin.

Therefore, before feeding, the air and acetylene gas in the hopper must be removed using nitrogen, so that the oxygen content is reduced to below 3%, before feeding can begin.
Explosion——1%————–——–——–
Acetylene is a flammable and explosive gas; when mixed with air in certain proportions, it can cause an explosion. Therefore, before feeding, the air and acetylene gas in the hopper must be removed using nitrogen, so that the oxygen content is reduced to below 8%, before feeding can begin.
