Issues with the superheating burner in the Topsoe section of the Kellogg process
Thread Content
Everyone: Please discuss the precautions regarding the ignition and normal operation of the furnace superheater burner in the Kellogg Process Topso section.
There’s no problem with using overheated burners, after all, the auxiliary furnace was already running at that time, and many burners on the roof of the furnace were also ignited. The temperature of the flue gas coming from these two sources was already high enough; in such conditions, manual ignition is actually quite quick. But if there is a procedure to follow, then follow it.
When igniting the superheated burner, it is necessary to pay attention to monitoring the flue gas temperature in the superheating section as well as the temperature of the high-pressure steam. To ensure the accuracy of the high-pressure steam temperature, it is necessary to slightly open the valves in the high-pressure pipeline network to allow the steam to flow.
It is relatively easy to ignite the superheated burner, but attention must be paid to the temperature of the coiled tubes, especially since it has a significant impact on the high-pressure steam coiled tubes. During ignition, care should be taken to prevent large fluctuations in the steam system, as well as to monitor the liquid level in the steam drum. Normally, check whether the burners have stopped working, but try to use as few burners as possible – it wastes natural gas and is not energy-efficient. Personal opinion. . . . .
