Regenerative Thermal Oxidizers (RTO)
from Combustion Controls Solutions &
Environmental Services Inc. provide
efficiency and effective volatile
organic compounds (VOCs), hazardous air
pollutants (HAPs), and odorous emissions
control for a wide range of processes.
Regenerative Thermal Oxidizer units are
best known for their superior heat
processing capabilities versus other
oxidizing units; and are mainly used in
the
• Chemical and pharmaceutical industries
• Paint finishing and coating industries
• Printing presses
As the process gas and VOC contaminants
enter the twin bed RTO through the inlet
manifold, a flow control valve directs
this gas into an energy recovery chamber
all while preheating the process stream.
Moving towards the combustion chamber,
the process gas and contaminants are
progressively heated in the stoneware
bed.
The VOCs undergo a chemical reaction as
they are oxidized, and then converted to
heat energy into the second stoneware
bed. Thus, reducing any need for
auxiliary fuel requirements. The
stoneware bed is heated, and the gas is
cooled so that the outlet gas
temperature is only slightly higher than
the inlet temperature. The flow valve
switches which alternate the stoneware
bed between inlet and outlet phases. If
the process gas contains a sufficient
amount of VOCs, the energy released from
the combustion will self-sustain
operation.
For example: an RTO at 95% thermal
energy recovery may have an outlet
temperature of 77° F, 25° F higher than
the inlet, process gas temperature.
In an effort to minimize the dependency
of an operator Regenerative Thermal
Oxidizers’ use PLCs, which are digital
computers that are automated
electromechanical controls.
