I'm guessing there's few coal buffs here so could someone educate me on thermal coal please?
The tables below are of unwashed coal for use in thermal power generation.
My question is this - Which of these is a better product & why?

(sorry for the mix match of tables as I've copied them from different reports)
I think the top table is a superior product for thermal power because it has a lower ash content & higher calorific Value?
Would that be correct?
In table number 2, I've seen the values AFTER washing which reduced the ash slightly (down to 42.6%), Volitile matter up (to 20.1%) and the calorific value increase from 13.7 to 15.7.
I'm comparing 2 different companies operating in the same region and trying to establish who has the better product for power generation.
