THERMAL DIAGNOSIS OF FIRED HEATERS
Your partners for performance and safety in refinery and petrochemical processing
THERMAL
DIAGNOSIS
In every
refinery or petrochemical plant, the fired heaters are the heart of the
process. Without your furnaces running properly, your operation will be severely
affected, or completely shut down. Your plant will not be generating profit
anymore.
Failures can be violent and cause hazards to
people and damage to important assets. Opportunity costs for lost production
can be huge. Cronholm will diagnose the condition of your fired heaters and
give you advice. Our long experience will work in your favor, ensuring trouble
free operation.
THERMAL
IMAGING
We use
Infrared Thermography in order to obtain an image of our target and temperature
measurements. Diagnosis using Infrared Thermography is the only way to get
full information about your furnaces during operation. Many things we can see
during operation are difficult or impossible to diagnose during a
shutdown. It is all done during full operation, through the viewports of
the firebox.
Of course,
the thermal images are not the only data we rely on! We collect a lot of
information in addition to that, in the field and from process data.
Conditions
and issues we will detect:
- Coke buildup and other internal
fouling
- Excessive scale and external fouling
- Burner problems
- Flame impingement
- Imbalanced heating
- Dry zones in tubes
- Thermocouple malfunction
- Tramp air inleakage in the firebox
- Inleakage of snuffing
steam/condensate
- Afterburn issues
- Broken tube guides
- Defective hangers and supports
