This project consisted of retubing the convection section, modifying the radiant section and installing low NOx burners. We developed the detailed engineering and fabrication drawings for this revamp. We also developed the detailed specifications for tubes, finning, tube supports, burners, burner supports, fabrication and erection. We floated enquires, evaluated vendor proposals, and made recommendations to our clients for placing a direct purchase order to the vendors. We carried out testings on the burners and checked the parameters while the heater was running with full capacity.
The heater was commissioned in April 2004 and has been running successfully since. The client is able to process more throughput than the design. The tube skin temperatures are very low. |
