                  煤气发生炉的常见故障清除方法Common trouble removal method of gas generator

                      煤气发生炉的常见故障清扫

                      1、煤气加压机突然停车

                      因为某种因素停电,加压机中止作业。这种情况就会突然影响到煤气发生炉。其特征为:炉出煤气压力大幅上升,炉底压力也添加。必定摆开放散,下降风压,关小风阀,下降饱满温度。注意风阀不能关死。假如长期停电,按热备操作。

                      2、空气鼓风机泊车

                      鼓风机和加压机在规划上是联锁的,加压机泊车,鼓风机也就自动中止作业。但也应防范联锁失灵(使用热煤气无冷却净化的不存在联锁问题)。煤气出口压力降至零。这时,不管是使用哪一种煤气炉,都有必要向炉底加大蒸汽流量,保证炉内正压,一起,封闭空气阀,视情况摆开放散。并当即通知加压机中止作业。防止出现炉内负压进入空气。

                      3、加煤机毛病

                      加煤机出现毛病,应停炉修补。停炉应停完全,不行转热备修补。假如是多台炉并联作业,应加又竖管水封水,堵截进入煤气总管通路,并严厉拟定修补计划,不行盲目胡来形成事端。

                      4、蒸汽包缺水(常压煤气发生炉不存在)

                      蒸汽包缺水,注意在未查明因素前,千万不行上水。处理办法:一是先翻开水位计放水旋塞放水,若发现有少数水显示,阐明缺水时刻不长,能够上水。二是翻开水位计旋塞无水显示,阐明缺水时刻较长,一起要观察蒸汽包压力改变,假如这时压力和正常运转压力相同,阐明缺水还不严峻,蒸汽压力现已超越作业压力,阐明水夹套缺水相当严峻。这种情况,应按紧迫停炉操作,并禁止向炉夹套上水,防止爆破事端发作。

                      5、空气管道煤气逆流

                      空气管道在正常作业时,煤气不会逆流到空气管道,可是,假如是俄然停电,煤气就有可能从炉底回来到鼓风箱中,因为逆止阀不起作用就会使煤气回来到空气总管至鼓风机,因为回来的煤气温度较高(600度以上),在空气管中和空气混合,到达爆破指数,就会天然爆破,结果相当严峻。

                      其防范办法:

                      (1)保证逆止阀密封牢靠;

                      (2)停电后要加大蒸汽量向炉内送蒸汽,保持炉内正压;

                      (3)停电后,要以最快的速度封闭空气阀,堵截进入炉底空气的通路,防止空气进入炉内导致事端。

                      (4)视煤气出口压力情况,摆开放散、下降炉底压力,不让煤气向鼓风箱返流。

                      注意:来电后,有必要先把空气总管中的煤气用蒸汽吹扫,然后才干转入正常运转。

                      6、预防热备转正常生产时炉内爆破。

                      热备炉转正常生产时有两种爆破情况,第一种是刚向炉内送风就发作爆破,第二种是在正常送风过程中发作爆破。

                      第一种爆破的因素是:在热备过程中,有有些煤气回来到鼓风箱中,因转正常运转,这有些煤气随同空气进入炉内,当煤气和空气混合后到达爆破指数时,遇到氧化层的红火即发作爆破。其危害程度相当严峻,具有关材料报道,爆破发作的破坏力足以把煤气发生炉撕裂,并导致火灾。为防止事端发作,在起动风机前,有必要把空气管道中的煤气用蒸汽吹扫洁净。

                      第二种爆破因素:热备状态的炉内氧化层温度较低,乃至有的氧化层火现已平息。这时假如风压调整的较大,空气进入炉内,一有些空气中的氧在氧化层中助燃,而在另一端的空气没有助燃,而是混合在煤气中发作爆破。消除这种爆破景象的办法:先调小风量,待炉内氧化层均匀树立好后,在慢慢添加风量。一起要注意少加煤,禁止开炉就大量加煤的做法,待氧化层树立转入正常后,视炉内情况在多加煤。

                  Common fault cleaning of gas generator

                  1, gas pressure machine suddenly stopped

                  The pressurizer stopped working because of a power failure.This situation will suddenly affect the gas producer.Its characteristic is: the furnace gas pressure rises greatly, the furnace bottom pressure also increases.Must spread, drop the wind pressure, close the wind valve, down full temperature.Note that the air valve must not be closed.If long - term power failure, according to hot standby operation.

                  2, air blower parking

                  The blower and the pressure machine are interlocked in the planning, the pressure machine parking, the blower will automatically stop operation.But also should prevent interlock failure (the use of hot gas without cooling purification does not exist interlock problem).The gas outlet pressure dropped to zero.At this time, no matter which kind of gas stove is used, it is necessary to increase the steam flow to the bottom of the furnace, to ensure the positive pressure in the furnace, together, closed air valve, according to the situation spread.And immediately notify the pressure machine to stop the operation.Prevent the furnace negative pressure into the air.

                  3, add coal machine fault

                  If there is something wrong with the stoker, it should be stopped and repaired.Stop furnace should stop completely, do not turn to heat repair.If be a lot of furnace parallel operation, answer to add standpipe water to seal water again, block off to enter gas main path, draw up repair plan sternly, do not come to form trouble blindly.

                  4, steam bag water shortage (atmospheric pressure gas generator does not exist)

                  Steam bag water, pay attention to the unknown factors before, do not water.Treatment method: first, turn over the water level meter water cock water, if found a few water display, clarify water shortage time is not long, can be on the water.The second is to turn over the water level gauge cock no water display, clarify water shortage time is longer, together to observe the steam pressure change, if the pressure and normal operation pressure is the same, clarify water shortage is not severe, steam pressure has exceeded the operation pressure, clarify water jacket water shortage is quite severe.In this case, it is necessary to stop the furnace immediately and prohibit water on the furnace jacket to prevent the explosion.

                  5, air pipeline gas reverse flow

                  Air pipe during normal operation, the gas will not flow into the air pipes, but, if be but Russia is a power outage, it may come back from the bottom of the furnace gas into the drum bellows, because non-return valve doesn't work can make the gas back to the air duct to the air blower, because back gas high temperature (above 600 degrees), in the air pipe and air mixing, reached the blasting index, natural blasting, the result is quite serious.

                  Preventive measures:

                  (1) to ensure the tight sealing of the reverse check valve;

                  (2) after the power failure to increase the amount of steam to the furnace to send steam, to maintain the furnace positive pressure;

                  (3) after power failure, close the air valve at the fastest speed to block the passage into the air at the bottom of the furnace and prevent the air from entering the furnace and causing trouble.

                  (4) according to the gas outlet pressure, spread out, reduce the pressure of the furnace bottom, do not let the gas to the bellows flow back.

                  Note: after a power call, it is necessary to steam off the gas in the air main before it can be turned into normal operation.

                  6. Prevent blasting in furnace when hot preparation is transferred to normal production.

                  There are two kinds of blasting when the hot standby furnace turns to normal production, the first one is the burst blasting when the air is sent into the furnace, the second one is the burst blasting in the normal process of air supply.

                  The first blasting factor is: in the process of hot preparation, there is some gas back to the bellows, due to normal operation, some of this gas along with the air into the furnace, when the gas and air mix after the arrival of the blasting index, encounter oxidation layer of red fire burst.Its harm degree is quite severe, have concerned material to report, the destructive force that blast attack is enough to produce gas to produce furnace to tear, cause a fire.In order to prevent the incident, before starting the fan, it is necessary to clean the gas in the air pipe with steam.

                  The second kind of blasting factor: the temperature of oxidation layer in the furnace in the hot standby state is low, and even some oxidation layer fire has subsided.At this time if the wind pressure adjustment of the larger, the air into the furnace, some of the oxygen in the air in the oxide layer combustion, and at the other end of the air did not support combustion, but mixed in the gas burst.The way to eliminate this kind of blasting scene: first adjust the small air volume, wait for the oxidation layer evenly set up in the furnace, slowly add air volume.Together to pay attention to less coal, prohibit the practice of adding coal to a large number of furnace, after the oxidation layer into the normal, according to the furnace situation in more coal.

                  The company has long been engaged in the design, manufacture, installation, commissioning and other technical services of gas generator and two-stage gas generator.Interested contact!Tel: 86-13676907460                    email: zzkyjx@163.com
