I justgot my coal delivered and while moving the bags downstairs i found a lot of water leaking out of them.. will that effect the coal or will it dry and be ok?

Wet or dry-it doesn't matter. Anthracite doesn't absorb water.

When I fill my bin the coal is always wet, less dust that way.

You can run a hose over it and throw it on the fire. The only issue with wet coal that has been brought up is the potential for it to exacerbate corrosion problems inside hoppers. Other than that you're fine.

A little wet is good if you don't want any dust.

Agreed, the Powder River Basin bit coal we ship to the power plants has been as high as 24% moisture at the time of loadout. It sucks on the freight cost because the railroads do charge for shipping the water. I just hope you aren't paying for the weight of the water.

You are but it's factored into the cost, just like if you go to the quarry and get sand... Lot's of water.

Over a 5 ton load you might have 300 lbs. roughly, Changes by the size of the coal and how long it's been allowed to drain. It doesn't add up to much. You can request dry coal from off the stock pile from some dealers but this is generally a bad idea. I've had some customers do it in the past but they have only done it once ;) . Most breakers have pockets where the coal is run over a screen to be washed one last time before its put into the truck, not sure about the what/how for a bagging plant. The dirt and dust removed can add up to a lot especially for larger sizes like nut and will make up for the water... you'll get a very clean product with some moisture content which is very preferable to a dirty dry product even if you are getting a litle more.

If it's rice coal and you are running a stoker, you don't want it dripping wet. It won't feed right, it will bridge in the hopper. Damp coal is ok.

If the coal is really clean it shouldn't do that. ;)
