The incinerator must also have a system that continuously measures and records the gas temperature at the combustion chamber outlet or, in the case of an incinerator that has more than one combustion chamber, at the outlet of the final chamber.
In addition, an incinerator with a design feed rate equal to or greater than 1 ton per hour must have a system that continuously measures and records the opacity of the combustion gases or the concentration of the particles emitted into the atmosphere.
An incinerator with a design feed rate equal to or greater than 2 tons per hour that burns halogenated materials must have a system that continuously measures and records the concentration of hydrogen chloride in the combustion gases emitted into the atmosphere.
