Besides the affects of corrosion on the hopper should be none. Only trouble I've heard any customers comment on about burning wet coal was if it was barley which is much smaller than rice and holds the moisture more. Obvioulsy you don't want it dripping wet but moisture should not affect it.
I have a old placard here from Van-Wert and they reccomend
the coal be damp. Many old timers will even tell you to keep it damp. If it has any beneficial affect I really don't know.
