Is the H2 content dangerous?
Thread Content
The boiler is a gas boiler; the composition of the gas is as follows: CO2: 1.87%, CO: 9.164%, C2H2: 0.596%, CH4: 0.357%, H2: 10.63%, H2O: 43.21%, N2: 33.672%, AR: 0.418%
From h2 to 5, it explodes zha
It’s not dangerous, but its calorific value is low, so more gas will be used.
Lacks the conditions for explosion
It is normal for factory exhaust gas to contain hydrogen as a fuel gas; there is no problem with that
The explosion limit of hydrogen in air is 4%-74.2%. If hydrogen is ignited in oxygen at the outlet of the gas duct, the local concentration becomes very high. The explosion limit refers to the condition where hydrogen and air (or oxygen) are thoroughly mixed and their molecules intermingle, which is necessary for an explosion to occur. However, the hydrogen emerging from the gas duct is ignited before it has had time to disperse into the oxygen, so no explosion takes place.
