Flammability limits of ammonia-air mixtures
WebThe addition of 4% ammonia resulted in a 10% to 20% decrease in burning velocities. Both simulations and experiments showed that adding ammonia to methane-air mixtures results in an increase in NO concentrations, especially at stoichiometric composition, and a minimal effect on CO formation. Near the flammability limits, ammonia of less than 0. ... WebFor this substance/mixture no limitations of extinguishing agents are given. 5.2 Special hazards arising from the substance or mixture Nitrogen oxides (NOx) Not combustible. Ammonia solution itself is not flammable, but can form an ignitable ammonia/air-mixture by outgassing. Ambient fire may liberate hazardous vapours. Fire may cause evolution of:
