Regarding the moisture content of coke

Question: What is the relationship between the moisture content of coke in wet quenching and the size of the coke particles? Thank you! :loveliness:
Please clarify your question: Are you asking about the impact of wet quenching on the moisture and lump size of coke? Should I ask something else?
Moisture content: 4-6%； The lump size mainly depends on coal blending and coke oven thermodynamics. However, low-moisture coking is divided into cases with high water volume and low water volume; an excessive opening degree (i.e., excessive pressure) can cause severe coking collapse, resulting in more coke dust and water-soluble coke dust.
Generally, the size of coke is related to the type of coal used and the method employed for quenching it. The use of dry quenching can increase the M40 value of coke by 3%–5%, while the M10 value can decrease by 0.2%–0.5%. In other words, the size of the coke improves. As for moisture, I don’t think there is any connection between it and the size of the coke. However, there is definitely a relationship between moisture and quality, as well as between the method of quenching and the size of the coke
The moisture in wet quenching is unrelated to the lump size
It is wet quenching of coke; does the quality of the coke being poor, with small or large lumps, have no impact at the same water volume? :)
The moisture content for quenching coke is generally kept between 3–5%. When the coke particles are large, the quenching effect is poorer; in such cases the moisture content may be lower. However, attempting to extinguish the red-hot coke might result in a higher moisture level
During wet quenching of coke, the moisture content of the coke is around 2% to 6%, with variations depending on the conditions of water spraying for drainage and the particle size of the coke； During dry quenching of coke, the coke also absorbs water vapor from the air during storage and transportation, resulting in a moisture content of 0.5% to 1% in the coke.
The size of coke is inversely proportional to its moisture content; in other words, the smaller the size of the coke, the higher its moisture content.
In wet quenching, there is a difference in moisture content between large coke pieces and small to medium-sized coke pieces; due to their different surface areas, they absorb different amounts of water, usually 2–3 times more
