How do I light a top-fired furnace?
Thread Content
Our factory has new top-fired furnaces; we haven’t used them before, as we have always used cylindrical furnaces； I would like to ask if the top burner has a pilot light? If not, how can it be ignited? Or automatic electric ignition? I hope all the marine enthusiasts will answer actively. Thank you!
Ah, ah… isn’t there any expert to take over?

Perform a leak test on the large and small burner systems and replace the air with nitrogen to ensure that the oxygen content is below 0.5%； 2. Introduce gas into the gas system ； 3. Start the top-burning furnace blower and exhaust fan, and open the outlet valve to ensure that the negative pressure inside the furnace does not become too high ； 4. Light the stove: Start by lighting the burners in the four corners, and gradually move towards the center ； Increase the number of burners further, determining the exact count based on needs. 5. Adjust the opening degree of the exhaust and intake fan outlet valves according to the negative pressure in the furnace. Regarding ignition: a torch can be used, or an electron gun can also be used for ignition ； Make your choice based on the conditions provided by the organization.
