Like all hazardous waste incinerators in the U.S., our permitted hazardous waste incinerators are highly controlled and regulated such that the emissions from disposal of explosive wastes are cleaned of any harmful chemicals, particulates, and heavy metals. This is accomplished by a state-of-the-industry air pollution control system (APCS) which cleans all of the emissions from our incinerators such that they meet the MACT standards for hazardous waste incinerators.
Our APCS consists of a secondary combustor which raises the exhaust gas temperature coming from the two incinerators to a minimum of 1800 degrees F, with a residence time of at least 4 seconds at that temperature. Following the secondary combustor, the exhaust gases enter a spray dryer where the gases are rapidly quenched to 375 degrees F. Soda ash (sodium carbonate) can be added to the quench water as necessary to neutralize acid gases. From the spray dryer, the exhaust gases, enter baghouses which filter the particulate from the gas stream. Cleaned exhaust gases then exit the system through our 215 ft high stack. As the gases exit the stack, they are continually monitored by our continuous emissions monitoring system to ensure that all of the APCS equipment upstream are functioning properly.
