Students who are aware of this, could you please explain roughly? I heard that the nitrogen oxides produced by ammonia torches are not environmentally friendly
It is highly environmentally harmful; the products of ammonia combustion are nitrogen oxides, which cause photochemical smog near the ground level and can also lead to acid rain. The specific reactions are as follows: 1. The photolysis of NO2 in polluted air is the initial reaction in the formation of photochemical smog. ( Chemical formula: NO2 == NO + O (under light exposure) O + O2 == O3 2NO + O2 == 2NO2 Analysis: 2NO2 (emitted) == 2NO + 2O (under light exposure) 2O + 2O2 (in the air) == 2O3 (irritating gas) 2NO + O2 == 2NO2 (NO2 is produced, triggering further reactions) In summary: 3O2 == 2O3 (under light exposure, with NO2 present). This type of smoke causes harm to humans and animals mainly by irritating the eyes and mucous membranes, causing headaches, breathing difficulties, worsening of chronic respiratory diseases, and abnormal lung function in children. Ozone is a strong oxidizing agent that has a distinctive odor at a concentration of 0.1 ppm. It can also reach the deeper layers of the respiratory system, stimulating the mucosa of the lower airways and causing chemical changes; its effect is similar to that of radiation, leading to chromosomal abnormalities and the aging of red blood cells. Products such as PAN, formaldehyde, and acraldehyde are irritating to the eyes, throat, nose, etc., of humans and animals, with an irritation threshold of around 0.1 ppm. Furthermore, photochemical smog can trigger asthma attacks in patients with asthma, and it can cause worsening of chronic respiratory diseases, breathing difficulties, and damage to lung function. Prolonged exposure to oxidants can reduce the metabolism of human cells and accelerate aging. PAN is also a potential agent that can cause skin cancer. The first incident that occurred in Los Angeles, USA, in 1943 resulted in the death of over 400 people. Therefore, in the United States, ammonia must under no circumstances be burned. With the principle of \"Environmental damage is my responsibility,\" we recommend that our company dilute it with water before discharging it into farmlands or similar areas, or recycle it instead. Eliminate burning!

Reply to 3# hbzyycc: Since ammonia cannot be burned, why do so many ammonia synthesis plants still install ammonia-burning flares? Are there any good methods, such as using fuel gas for combustion, to minimize the generation of NOX during ammonia combustion and reduce pollution? Also, is it okay to release ammonia directly into the atmosphere if it isn’t burned?
I am strongly opposed to building ammonia-burning torches, but some property owners insist on doing it; I really can’t believe it
I really designed a ammonia burning torch set – did I make a mistake? :(
Mistakes are mistakes – it’s essential to ensure the safety of torches; otherwise, serious problems can arise. While not being environmentally friendly may not lead to major safety accidents, controlling emissions does contribute to environmental protection
It’s indeed not environmentally friendly; the advantage is that it eliminates meaning. Deceiving the common people
