Furnace cleaned using remote mechanical operation
A German refinery requested that Tube Tech develop a robotic cleaning technology to clean deep in between both square and triangular pitch rows of convection tubes within its fired heater to improve poor cleanliness achieved using traditional water jetting and chemical service contractors.
The “Remote Controlled Furnace Robot” was born, delivering an unprecedented level of cleanliness within record time.
This included the removal of fused refractory that had cemented itself between the tubes over many years.
The client had previously trialled many systems including chemicals, water jetting, abrasive shot blasting and dry ice, which were limited in success as blast methods only clean what the operator can see.
Access deep inside and between the furnace rows was never achieved.
Refractory damage has always been an issue when using conventional cleaning methods.
