Safe Operation Of Low Nitrogen Burners

Start-up operation of low nitrogen burners

1. For the newly installed furnace body, carefully check whether the gas meets the requirements of the burner before commissioning; check whether the detection instruments on the gas supply pipeline are normal and whether the opening and closing of the pipeline valves are normal, and whether it is convenient for future use and maintenance.

2. For newly installed pipelines, the installation reliability of all pipelines and the tightness of pipelines should be carefully checked.

3. Users who use a separate gasification station must ensure that the gas supply volume and gas supply parameters meet the requirements for safe combustion.

4. Operators should carefully read the equipment instructions and master the knowledge and methods of safe operation.

5. Check whether the gas valve is open every time before starting, otherwise the burner will not work.

6. Turn on the power control button on the control cabinet, and the digital display will display the current temperature in the furnace. The temperature of the newly installed furnace body is the ambient temperature.

7. Start the fan control button, and the fan installed on the furnace body will work. If the fan damages the control cabinet, it will automatically protect it from entering the next step.

8. When there is no abnormality in the operation of the combustion-supporting fan, the combustion control button is activated again. At this time, the combustion program controller starts to work. It performs ignition, air supply, flame detection, and other procedures through a certain program to finally achieve safe combustion.

9. When the combustion controller receives a signal that is not conducive to combustion (for example: ignition failure, unstable air pressure, circuit problems) and other problems, the combustion controller immediately turns off the gas and sends an alarm signal.

10. If the combustion controller alarms, it must be manually reset by the operator after the fault is resolved before it can continue to work.

11. For the operation of the entire equipment, the operator should refer to the furnace body safety operation rules and production process requirements to operate.

12. When the control temperature needs to be adjusted according to the production process requirements, the operator should refer to the manual of the intelligent numerical control table to adjust.

Shutdown operation

(1) There are two cases of shutdown: the first is: when the temperature in the furnace reaches the set value, it will automatically shut down. At this time, the operator does not need to do anything. When the temperature in the furnace is lower than the set value, the controller will automatically turn on.

(2) The second is: in the case of artificial shutdown and shift shutdown, the operator should follow the reverse order of starting the machine (a. Turn off the combustion control button first, b. Turn off the fan button, c. Turn off the power button at last twist) to operate the shutdown.

(3) When the shutdown time is long, the operator should close the gas pipeline valve to avoid gas leakage.
