I have a question about coke cooling.
Thread Content
I majored in chemistry, so I don’t know much about coking. I came across a coking plant project these days, which said that the coke was sprayed with water to cool down directly after it came out of the furnace. I have a question about this, that is, carbon reacts with water at high temperatures to form carbon monoxide and hydrogen. Is it appropriate to discharge it directly? Is there any danger? Such as poisoning, explosion, etc. I hope some hero can explain it. Thanks in advance.
The classmate was overly worried and had been using water to quench the coke before adopting dry coke quenching technology. Although carbon can react with water to generate carbon monoxide and hydrogen at high temperatures, the reaction is unsustainable without continuous heat supply - there may be a slight reaction (the flammable gas produced will burn together with the hot coke), but the water mainly vaporizes and absorbs the heat of the coke by the latent heat of phase change - causing the red coke to cool down instantly. After the temperature drops, the water and carbon no longer react.
