The principle is that carbon monoxide produced by incomplete combustion results in secondary combustion.
Due to the low temperature of the ZHI furnace and insufficient oxygen supply, incomplete combustion is likely to occur during the ignition and shutdown of the boiler.The products of incomplete combustion, such as carbon black, coal powder and oil points, enter and deposit in the tail of the boiler with the flue gas, which reduces the heat transfer effect of the heating surface of the tail and increases the exhaust temperature.
A secondary combustion occurs when the exhaust temperature rises to a certain level and there is sufficient oxygen for combustion.Garbage incinerator is the equipment for incineration and disposal of garbage. Garbage is burned in the furnace and turns into waste gas and enters the secondary combustion chamber. It is completely burned under the forced combustion of the burner and then enters the spray dust collector.
Secondary combustion conditions
1. The existence of carbon monoxide;High temperature;There is excess oxygen.
2. The oxygen content decreased rather than increased, indicating that the complete combustion of CARBON monoxide in the dilute phase consumed oxygen.However, the existence of such a situation for a long time indicates that the secondary combustion is very serious. If it is the complete regeneration process of the pre-burned tank, it may be because the burning intensity in the tank is insufficient or the distribution pipe is broken, and the catalyst stays in the tank for a short time.
3, add CO additives, if still cannot eliminate the secondary combustion, according to the equipment can bear the highest temperature and smoke machine condition, according to the situation cut off the main wind, find the cause.
