This graphic shows how airflow travels and heat is transferred inside
an Anguil two bed Regenerative Thermal Oxidizer.
Here process gases are pushed into the inlet manifold of the RTO
via a system fan.
These Volatile Organic Compounds and Hazardous air pollutants are
routed into the first bed of ceramic energy recovery media.
They are progressively heated prior to entering the combustion chamber where
temperatures break apart the contaminated compounds.
Once this exothermic reaction takes place
cleaned compounds exit via the second RTO media bed,
releasing upwards of 97% of the thermal value.
When the second bed is completely heated,
airflow is reversed within the RTO so that the outlet bed
becomes the inlet and vice versa.
Electronic control systems dictate when and how often this cycle repeats to
maximize energy recovery within the RTO.
Often the oxidizer will self-sustain without any need for
supplemental fuel for operation.
Here you see a more detailed view of the Anguil flow control system
also known as poppet valves. The dual-disc set up alternates airflow into the media
beds to maximize energy recovery with an oxidizer,
switching every two to four minutes depending on the process conditions.
Dual ceiling disks minimize the valves overall stroke lenght
and hinged access doors make periodic maintenance very easy.
