Why my coal is wet? - The UK's leading coal and firewood ...

Why my coal is wet? While the appearance of wet fuel can cause concern when first delivered the perception that the fuel is “wet through”, “sodden” or “unusable” is not correct. During the manufacture of solid fuel briquettes the moisture level can be between 7 – 12% (approximated); this level of moisture has no detrimental effect to the ignition or performance of the fuel ...
