1.控制和燃燒系統(tǒng)的安全隱患
1. Safety hazard of control and combustion system
1）燃燒器的內(nèi)部泄漏：如果燃燒器閥組內(nèi)部有泄漏，配備燃燒器的泄漏檢測(cè)器發(fā)生故障或完全沒有配備泄漏檢測(cè)器的燃燒器，可燃?xì)怏w將進(jìn)入爐子，并一旦點(diǎn)燃，爐子可能爆炸。這是燃?xì)忮仩t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）燃燒不充分：燃燒器空燃比控制不當(dāng)會(huì)導(dǎo)致天然氣燃燒不充分而產(chǎn)生一氧化碳?xì)怏w，可能導(dǎo)致鍋爐房的一氧化碳中毒。
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）干燒：如果低水位報(bào)警和超低水位鎖定保護(hù)裝置發(fā)生故障，很容易導(dǎo)致鍋爐干涸。如果不采取有效的緊急措施，則錯(cuò)誤的供水將導(dǎo)致鍋爐爆炸。
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?xì)夤艿阑蝈仩t房煙道漏氣可能導(dǎo)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.鍋爐安全配件包括安全閥，溫度計(jì)，壓力表，水表等的潛在安全隱患未定期檢查或未按規(guī)定進(jìn)行定期排放試驗(yàn)，導(dǎo)致安全隱患配件和儀器；
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，常壓鍋爐采用壓力運(yùn)行，壓力鍋爐的超壓運(yùn)行可能對(duì)鍋爐本體造成不可逆轉(zhuǎn)的損害，甚至?xí)鸢踩鹿?，有可能?dǎo)致燃?xì)忮仩t運(yùn)行的隱患
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
這些是燃?xì)忮仩t在使用過程中需要注意的問題。這些不僅有得于控制發(fā)生安全事故，也有利于鍋爐的日常維護(hù)，通過這些檢查事項(xiàng)可以使鍋爐的使用壽命更加長(zhǎng)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.
