into the inner and outer nozzles changes. Rotating the FDR adjustment to the left

(clockwise) will increase the flow of gas in the inner nozzle, the gas velocity will be

faster, the flame will be shorter, and the energy release position will move forward.

Turning to the right (counter-clockwise) reduces the flow of gas to the inner nozzle,

the gas velocity slows, the flame gets longer, and the energy release position

recedes.

The adjustment of flame length and energy release position will affect NOx emission.

The general principle is: reducing the gas velocity will reduce NOx, but it must be

combined with the process to ensure that the flame shape meets the process

requirements

8.3

Other adjustments

The adjustment of the flame needs to be considered in combination with the up and

down, left and right adjustment mechanisms of the burner bracket. The angle and

speed of the combination of natural gas and combustion air have an impact on the

shape of the flame.

9. Burner stops

Close the gas/cooling air ball valve on down comers, disconnect the hoses, and remove

the burner from bracket.

Plug the hole in the middle of the seal plate with ceramic fiber.
