Get rid of club's fuel (8)
I believe the answer is:
firewood
'fuel' is the definition.
(I know that Firewood is a type of solid fuel)
'get rid of club's' is the wordplay.
'get rid of' becomes 'fire' (as in firing from a job).
'club' becomes 'wood' (wood is a kind of club).
'fire'+'wood'='FIREWOOD'
(Other definitions for firewood that I've seen before include "Kindling for 17 across" , "Substance for burning" , "Logs etc for fuel" , "Fuel from trees" , "Tinder" .)
