1.控制和燃烧系统的隐患
1. Safety hazard of control and combustion system
1）燃烧器的内部泄漏：如果燃烧器阀组内部有泄漏，配备燃烧器的泄漏检测器发生故障或完全没有配备泄漏检测器的燃烧器，可燃气体将进入炉子，并一旦点燃，炉子可能爆炸。这是燃气锅炉爆炸的主要原因之一。
1) Internal leakage of burner: if there is leakage inside the burner valve group, the leakage detector equipped with burner fails or the burner without leakage detector at all, combustible gas will enter the furnace, and once ignited, the furnace may explode. This is one of the main reasons for the explosion of gas-fired boilers.
2）燃烧不充分：燃烧器空燃比控制不当会导致天然气燃烧不充分而产生一氧化碳气体，可能导致锅炉房的一氧化碳中毒。
2) Insufficient combustion: improper control of burner air-fuel ratio will cause insufficient combustion of natural gas and produce carbon monoxide, which may lead to carbon monoxide poisoning in boiler room.
3）干烧：如果低水位报警和超低水位锁定保护装置发生故障，很容易导致锅炉干涸。如果不采取有效的紧急措施，则错误的供水将导致锅炉爆炸。
3) Dry burning: if the low water level alarm and ultra-low water level locking protection device fails, it is easy to cause the boiler to dry up. If effective emergency measures are not taken, the wrong water supply will lead to boiler explosion.
2.燃气管道或锅炉房烟道漏气可能导致中毒或爆炸事故。
2. Gas leakage in gas pipeline or boiler room flue may lead to poisoning or explosion accident.
3.锅炉配件包括阀，温度计，压力表，水表等的潜在隐患未定期检查或未按规定进行定期排放试验，导致隐患配件和仪器；
3. Potential safety hazards of boiler safety accessories, including safety valves, thermometers, pressure gauges, water meters, etc., have not been regularly inspected or regular discharge tests have not been carried out according to the regulations, resulting in potential safety hazard accessories and instruments;
4，常压锅炉采用压力运行，压力锅炉的超压运行可能对锅炉本体造成不可逆转的损害，甚会引起事故，有可能导致燃气锅炉运行的隐患
4. Atmospheric pressure boiler adopts pressure operation. The overpressure operation of pressure boiler may cause irreversible damage to the boiler body, even cause safety accidents, and may lead to hidden dangers of gas-fired boiler operation
这些是燃气锅炉在使用过程中需要注意的问题。这些不仅有得于控制发生事故，也有利于锅炉的日常维护，通过这些检查事项可以使锅炉的使用寿命更加长久。
These are the problems that should be paid attention to in the use of gas-fired boilers. These are not only to control the occurrence of safety accidents, but also conducive to the daily maintenance of the boiler, through these inspection items can make the service life of the boiler longer.
