Tube Tech Comment
“€8m energy saving is not an uncommon Client benefit after Robotic Cleaning of their Ethylene Fired Heater. Our Robots unlock this hidden and previously inaccessible saving by the removal of 90%+ fouling compared to 1% from conventional methods,” says Christian Chanel, Technical Sales.
“Every fired heater project has its unique challenges whether due to limited access, unknown fouling levels even design changes omitted from client drawings. All credit to our R+D team and site operators who proactively overcame every obstacle”.
Due to the huge financial and Co2 benefits I strongly recommend a yearly “Fouling preventative” clean as 1mm of fouling reduces overall heater performance by 10%!
“The root cause of the decreasing performance of the furnace was reduced heat transfer in the convection section due to external fouling.
After robotic cleaning by Tube Tech, the heat duty of each convection bank increased by 11% and the % stack loss reduced by 16%. The quality of high pressure steam generated was improved. Thorough cleaning avoided damage to the low temperature sections and flue gas fan. The external cleaning was a success and will similar savings over the next few years.
