Oxidizer

The oxidizer contains two or three chambers operating
in a regenerative mode. In the three bed technology,
the contaminated air passes through the first two
chambers, heated up from previous operation. The air
temperature is raised to minimum 300/350°C allowing
the oxidation of the VOC within the catalyst.

After the first oxidation process the hot air stream
passes through the third bed of catalyst and heat
exchanger mass, being cooled and heating the mass in
the process.

If the VOC concentration of incoming air is not enough
to keep the temperature above 300/350°C, then the
heating system located inside the reactor will heat the
air stream further for the needed time.

During the whole process the air stream is sucked
by the main fan and goes through the chimney. The
outgoing air is completely treated and can be used for
other heating purposes due to its temperature.

Additional heating energy

During the start-up of the VOC oxidizer, and also in
some situations where we don’t reach the ATP-Auto
Thermal Point, an additional heating energy is required.
The heating system is operated by electricity due to its
easy maintenance, and relatively small size, but can be
also used by gas heating.

Control unit

The system includes a control unit, by which all
necessary funcrions, as well as emergency functions
of the catalytic VOC oxidizer can be controlled. The
control unit is provided with all necessary inputs and
outputs needed for remoting.

Valves & instrumentation

The system includes all instrumentation and electrical
equipment needed in normal operations as well as in
emergency situations.
