ABSTRACT:
A process for minimizing the formation of nitrogen oxides in the disposal of industrial waste streams containing chemically bound nitrogen, the process comprising the steps of passing a combustion gas stream at about 1200.degree. F. to about 2000.degree. F. to a combustion chamber; mixing an industrial waste stream with a selected mixing ingredient to provide a waste stream mixture having a composition such that adiabatic combustion of the waste stream mixture would yield combustion products having a combustion temperature of about 1500.degree. F. to about 2000.degree. F.; injecting the waste stream mixture into the combustion chamber and contacting same with the combustion gas stream to combust the nitrogen containing compounds to form a composite combustion gas stream having a temperature of from about 1500.degree. F. to about 2000.degree. F. The composite combustion gas stream can be vented to the atmosphere after, preferably, passing same through heat recovery equipment. The selected mixing ingredient which is mixed with the industrial waste stream can be air, fuel or mixtures thereof.
