I'm new to it. I'm installing a Kaa-2, and I bought a load of rice from a coal guy here that hauls it in, so I can fire it off for a 2 day+ test [if I every get it done].
I can snap most of the pieces that I try fairly easily. Although some of it is very hard, some will even crush a bit, almost like our bituminous coal here. Even at the $150 a ton price [off season buy - good deal here], I'm a bit freaked. Thinks it's ok? I wonder if he had it stored where he previously may have stored bit stoker coal, and a little bit of it isn't anth.
I have 30 years of bituminous experience, and I know that you can't tell much at a glance. He didn't have any test data on it. I am sort of committed to take all that he has. Apx 6-7 tons.
