Amazing Way Of Cleaning Ash Of Flue-Cured Tobacco Furnace With Water !
The Principle Of Cleaning Chimney Ash By Throwing Water Into The Furnace Chamber Of A Flue-Cured Tobacco Oven Mainly Includes The Following Two Points :
I. Physical Effect
When water is thrown into the hot furnace, it will quickly vaporize into steam. The volume of steam is much larger than that of liquid water, generating a large pressure wave in the furnace. This pressure wave can loosen the soot attached to the inner wall of the chimney. At the same time, in the upward flow process, steam will impact the soot in the chimney and make it fall off from the chimney wall, thus achieving the purpose of cleaning soothing !
II. Chemical Effect
1. Reaction between water and carbon at high temperature :
Under high temperature conditions, water reacts with incompletely burned carbon in the furnace to produce carbon monoxide and hydrogen. This reaction will consume a part of carbon and reduce the source of soot production !
The carbon monoxide and hydrogen produced by the reaction are both combustible gases. They will burn in the furnace. The heat generated can maintain the temperature of the furnace and also help to loosen and burn the soothing !
2. Effect Of Water On Soot
Steam can dissolve some soluble substances in soot, reducing the stickiness of soot and making it easier to be removed !
Steam can also make some fine particles in soot agglomerate into larger particles, so that they can be more easily carried away by the air Flow !
This Method Has Certain Safety Risks
On the one hand, throwing water into a hot furnace may cause an. Water rapidly vaporizes at high temperatures to produce a large amount of steam, and the pressure rises sharply. If the furnace structure is not strong enough or the sealing is poor, it may cause the furnace to burst or components such as the furnace door to be blown open, causing harm to operators !
On the other hand, carbon monoxide generated by the reaction of carbon and water at high temperatures is a toxic gas. If ventilation is poor during the cleaning process, carbon monoxide may accumulate around and cause poisoning hazards. Moreover, the generated hydrogen is a flammable and explosive gas. If it mixes with air to a certain proportion and encounters a fire source, it may cause an explosion !
In addition, if the operation is improper, for example, if too much water is thrown or the water is not evenly distributed, it may affect the combustion state in the furnace and disrupt the normal process of flue-cured tobacco.
In conclusion, the method of throwing water into the furnace of a flue-cured tobacco oven to clean chimney ash is not very safe and should be used with caution. Appropriate safety protection measures should be taken, such as ensuring good ventilation and wearing protective equipment. It is best to consider adopting a safer professional cleaning Method !
