Flammability limits of ammonia-air mixtures
WebDec 31, 1995 · Ammonia`s flammability limits in air at standard atmospheric conditions are 14.8% (lower flammability limit, LFL) and 33.5% (upper flammability limit, UFL) … 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. ...
