RTO Inspection
Hydraulics
and Related Components
The
hydraulic components are one of the most
important safety requirements for your
total system operation. If your facility
experiences any power outage and/or
shutdowns, the accumulators extra
pressure volume will force all flow
control valves to the open position.
Correct flow control valve positioning
controls static ventilation during
shutdown and does not permit cold face
area over temperature exposures.
Flow Control Valves and Related
Components
Flow control valves are considered high
maintenance due to the effect of the
system operating limits, system airflow
reduction and decreasing total system
destruction efficiency.
Central Chamber and Related
Components
Central chamber internal insulation has
a very low thermal conductivity which
protects the exterior shell from the
high central chamber temperature.
Material flaking, large cracks,
excessive damage and excessive breakage
cause deterioration to the steel shell
(hotspots).
Cold Faces and Related
Components
The cold face retainer grid supports the
heat exchanger media (stoneware) is
inspected for damage to the grid
supports and damages caused by a faulty
flow control valve not seating properly.
Heat Exchanger Media (Stoneware) and
Related Components
Damaged heat exchanger media could cause
reduction of system airflow, increase
fuel usage due to poor preheat of air
and/or decrease total system destruction
efficiency.

Burner and Related Components
Burner safety and operation should not
be compromised. Burner nozzle and body
cracking, dirt build up, deterioration
and/or plugging of the orifices can
cause improper burner firing. Burner
sequencing of the purge and ignition
system should be tested every six
months. Burner permissive and safeties
are required to light and maintain the
burner safe operation. Accidents usually
can be traced to indifferent maintenance
of protective devices or failure to
immediately and properly remedy defects.
System Controls and Related
Components
The PLC programmable logic controller is
the thermal oxidizer system
intelligence. The PLC is dependant on
the sensing equipment and the signal
received to make the correct
determination. Therefore, it is
imperative the controller,
instrumentation and sensing devices are
all operating correctly and properly
calibrated.
