Is dry powder gasification better or water-coal slurry gasification better?

Present a pseudoproblem: Is dry powder gasification better or slurry coal gasification better?
It depends on how you view the issue. If we consider only the consumption aspects, without taking into account the suitability of different coal types, dry coal powder gasification is the best option – it requires significantly less oxygen and also less coal.
It’s a big question. In fact, if it were possible to apply the fluidized bed gasification technology used in modern coal chemical industries, or to use furnaces with a coal feeding capacity of 1,000 T/D, that would be very indicative. With coal being so cheap these days, it’s hard to say; before last year, I would have chosen pulverized coal without hesitation, but now it’s uncertain
If everyone already knows it’s a false proposition, then why ask? The gasification technology still needs to be determined based on the type of coal; there is no absolute good or bad technology.
Each has its advantages and disadvantages; it’s not possible to determine whether it’s good or bad alone. There are many factors such as the type of coal, and a comprehensive consideration is needed
