The burner of the low-nitrogen burner is the part that is directly heated. At the beginning of the ignition period, the internal air pressure may cause ignition failure or insufficient ventilation. How to solve this problem?
First, check that if the flow channel is closed, the incineration airflow will decrease, the air pressure in front of the flame plate will increase in response, the wind speed will increase, the turbulence will increase, and the airflow penetration ability will increase, which is conducive to enhancing the mixing of air with the body. And obtain good flame retardant stability.
The burner nozzle is equipped with a regulator to adjust the air channel between the burner nozzle and the flame plate.
When the flame shakes, it must be adjusted. In practical applications, it is necessary to adjust the booster boiler (compressor and gas turbine unit provide 0.2-0.4mpa incineration hot air) or a larger heat load.
From the above description, it can be seen that when the air duct of the burner nozzle is lowered, the position of the burner nozzle must be able to ensure that the air pressure level in front of the flame plate is almost always higher than the air pressure level behind the flame plate.
Generally, it is recommended to reduce the air channel in the incinerator and open the door of the fan inlet in response.
The incinerator must be set with a large output. In actual operation, the air duct in the incinerator must be placed in the middle position, and then the incinerator is started for debugging.
When the maximum output is reached, gradually close the air channel in the burner nozzle, close the damper at the fan inlet to the fully open position, and then move the flame diffuser of the burner nozzle forward and backward to adjust the airflow to make it suitable.
Note: During the adjustment process, do not close all the ventilation pipes in the incineration cover.
Make sure that the axis of the burner nozzle and the flame plate are the same. If the axis is not well aligned, the flame will not burn well, and the burner nozzle will burn due to local overheating. The axis alignment can be checked through the inspection hole at the rear of the incinerator.
Then, tighten the screw on the adjustment handle, adjust the position of the incinerator, and fix the incinerator.
Note: Check whether the ignition is stable.
If the air channel in the incinerator is closed too small, it may be difficult to ignite due to the high wind speed. If this happens, the channel must be gradually opened until the ignition is successful.
At this time, the setting position of the incinerator nozzle is this position. The small opening of the damping plate should meet the requirement that the gas pressure switch at the ignition position can be flexibly operated to ensure stable ignition. Otherwise, please adjust the opening of the damper again.
As a ** equipment, the low nitrogen burner should fully read the manufacturer's instructions. If the problem cannot be solved, the manufacturer's technical department should be consulted in time, and it must not be disassembled by yourself to avoid damage or danger.
