Points to pay attention to when adjusting methanol burners

When we adjust the methanol burner, do not blindly guess and adjust it. It requires quite professional technical knowledge and professional technicians to adjust, which can make the methanol burner work better and have a longer service life, because the machine The requirements of the various parameters of the machine are particularly strict. If we do not know the machine very well, it is recommended not to guess and adjust it, so as not to delay the life of the machine. Methanol burner adjustment requires not only solid theoretical knowledge, but also years of practical experience. Let's mainly talk about the precautions below: ① Use the flame detection monitoring window as one of the main monitoring screens. Keep the combustion in the furnace stable, the flame is bright golden yellow, does not deviate, does not stick to the wall, and has a good flame fullness. ② Maintain the air preheater inlet oxygen content within the range of 4% to 6%. When a dark red and long flame or even black smoke is coming from the chimney, the auxiliary air damper of the boiler should be adjusted in time to organize reasonable air distribution to maintain the air volume, The best combination of powder quantity keeps good combustion in the furnace. ③The coal level of the coal bunker should be monitored frequently to prevent the coal pulverizer from breaking down due to the burning of the original coal bunker. ④ When the boiler combustion is unstable, it is strictly prohibited to operate the boiler soot blowing and the start and stop of the pulverizing system. ⑤The flame situation should be observed on the spot, attention should be paid to the air leakage in the furnace, and all the fire holes and coke holes should be closed tightly. ⑥Operators should understand and master the characteristics of incoming coal in time, be aware of changes in coal quality, and organize reasonable combustion. ⑦Regularly observe and analyze the fly ash and bottom ash of the boiler, make timely combustion adjustments, and maintain the economic operation of the boiler. In the direct-blowing pulverizing system, the boiler operating load is directly related to the output of the coal mill, which makes the entire pulverizing system often unable to operate under the most economical conditions. Since the output of the pulverizing system is equal to the amount of coal burned into the furnace, the change of the system ventilation affects the ratio of primary and secondary air, thereby affecting the stability of the boiler operation and the combustion conditions in the furnace. The air volume and coal volume of the pulverizing system change with the changes in the operating load of the boiler, and the gas powder concentration in the system changes frequently. According to these characteristics, various influencing factors are comprehensively considered to carry out effective combustion adjustments to ensure the unit’s performance Safe, stable and economic operation.
