Gas-fired boilers are not only cleaner and more environmentally friendly, but also have higher fuel utilization rate and efficiency than other types of boilers. They are generally concealed in the industrial processing consumption of all walks of life in our country, and are used in many industries, such as chemical consumption, food processing, textile, paper making and so on. Many users who use gas-fired boilers tell us that when the boiler is just started, it will not ignite at all. Gas-fired boilers encounter this situation mainly because of the problems of extinguisher components and air pressure. According to different conditions, the following analysis can be made.

一、启动后前吹扫正常，但点不着火

1. Cleaning is normal before and after start-up, but it does not ignite.

1、电火气量缺乏：检查线路并修复

1. Lack of Electric-Fire Gas: Check Circuits and Repair

2、电磁阀烧坏、不工作(主阀、点火阀)：换新

2. Solenoid Valve Burn out, Not Working (Main Valve, Ignition Valve): Renovation

3、气压不稳定：调整气压规则值

3. Air pressure instability: adjust air pressure to regular value

4、风量太大：减小配风，减小风门开度

4. The air volume is too large: reduce the air distribution and the opening of the throttle

二、锅炉气压正常，点不着火

2. The pressure of the boiler is normal and it will not ignite.

1、点火变压器烧坏：换新

1. Burning out of ignition transformer: renewal

2、高压线损坏或零落：重新装置或换

2. High Voltage Wire Damage or Fragmentation: Re-installation or Replacement

3、点火棒位置相对尺寸间隙过大或过小：重新调整

3. Ignition rod position relative size gap is too large or too small: readjustment

4、电极决裂或与地短路：重新装置或换新

4. Electrode Cracking or Ground Short Circuiting: Re-installation or Renovation

5、间距不适宜：重新调整

5. Inappropriate spacing: readjustment

三、锅炉点着后5~6秒后熄火

3. Flameout after 5-6 seconds of boiler ignition

1、气压缺乏，压降太大，供气流量偏小：重新调整气压，清算滤网

1. Lack of air pressure, too large pressure drop and too small supply air flow: readjusting air pressure and clearing filter screen

2、风量太小，熄灭不充沛，烟色较浓 ：重新调整

2. The air volume is too small, the extinguishment is not sufficient, and the smoke is strong: readjustment

3、风量太大，呈现白气：重新调整

3. Too much air, showing white air: readjustment
