Gas boiler accidents are also diverse, in addition to the occurrence of coal-fired steam or hot water boiler accidents, but also may occur such as furnace and flue explosion accidents, the following Shandong Gas Boiler Factory will give you an analysis of the causes of such accidents and treatment principles, hoping to arouse everyone's attention, through the small edition of the explanation to help you!
炉膛及烟道爆炸是燃气锅炉中常见事故 。这种事故在点火或运行中都可能发生 ,尤其是在点火或维修中发生得多 。严重时炉墙崩塌 , 砖块横飞 ,炉顶和烟道掀开 ,火焰和高温烟气向外喷射 ,这时极易造成人员伤亡 。
Furnace and flue explosion are common accidents in gas-fired boilers. This kind of accident may occur in ignition or operation, especially in ignition or maintenance. When the furnace wall collapses, bricks fly across, the top of the furnace and flue are lifted, flame and high temperature smoke are sprayed outwards, which is very easy to cause casualties.
Causes of Furnace and Flue Explosion:
(1)锅炉点火前 , 没有将炉膛内残余可燃气体排除 ,没有点火程序控制装置,或没有执行操作规程 ,盲目点火所致 。
(1) Before the ignition of the boiler, the residual flammable gases in the furnace are not removed, the ignition program control device is not available, or the operation rules are not carried out, resulting in blind ignition.
(2)锅炉运行期间突然熄火 , 没能及时中断燃料的供给 。
(2) During the operation of the boiler, the flameout suddenly failed to interrupt the fuel supply in time.
(3)当给油泵发生故障而使锅炉给气中断时 ,未将锅炉进气总阀关严 , 当给泵恢复正常时，使大量燃气进入炉内。
(3) When the feeding pump fails and the feeding gas of the boiler is interrupted, the main intake valve of the boiler is not closed. When the feeding pump returns to normal, a large amount of gas enters the furnace.
(4)当电路断电、送风机停转 , 未立即将电源开关拉开,切断气源, 当送电正常后燃气大量进入炉内。
(4) When the circuit is cut off and the blower stops running, the power switch is not immediately opened and the gas source is cut off. When the power supply is normal, a large amount of gas enters the furnace.
Treatment of Furnace and Flue Explosion
(1)应立即停炉, 同时切断电源、气源 , 防止事故扩大。
(1) Stop the furnace immediately, cut off the power and gas sources at the same time, and prevent the accident from expanding.
(2) Regulate the water level of the boiler to normal.
(3) Inspection of boilers with furnace and flue explosion.
(4) Furnace supervisors must strictly follow the operating rules. Whether it is the first ignition before the start-up of the boiler or the second ignition after quenching in the operation of the boiler, it must be carried out according to the ignition operation procedure.
