The combustion reaction of NH3 in the reactor? Answer: In the reaction furnace, the gaseous substances containing ammonia, aside from H2S, mainly consist of NH3. The combustion reactions of ammonia are as follows: ① NH3 + 0.75 O2 == 0.5N2 + 1.5 H2O – 89 Kcal; ② 2NH3 + 5/2 O2 == 2NO + 3H2O – Q; ③ 2NH3 == 2N2 + 3H2 + Q. The main purpose of feeding NH3 into the reaction furnace is to convert it into N2, which can then be released into the atmosphere
Catalytic oxidation of ammonia: 4NH3 + 5O2 = 4NO + 6H2O. Combustion of ammonia in pure oxygen: 4NH3 + 3O2 = 2N2 + 6H2O
As long as the furnace temperature exceeds 1250 degrees, the decomposition of ammonia occurs primarily into H2O and N2; if the temperature is lower, NO may be produced, and ammonia can also yield H2 and N2
Inside the reaction furnace, the gaseous mixture containing amino acids consists, in addition to H2S, mainly of NH3. The combustion reactions of ammonia are as follows: ① NH3 + 0.75 O2 = 0.5N2 + 1.5 H2O – 89 Kcal; ② 2NH3 + 5/2 O...

The reactions of NH3 in the reaction furnace mainly include three: (1) Reaction with O2: 2NH3 + 3/2O2 = N2 + H2O; (2) Decomposition reaction: 2NH3 = N2 + 3H2; (3) Reaction with SO2: 2NH3 + SO2 = 2H2O + H2S + N2. The third reaction is the main one.
