Clue is "33 per cent burn from this air combustion type"
Solution is "thirdstream"
I don't get it...can someone explain please? Kind regards, Guitarboogie.

A stream is a burn.
Mind you "thirty-three percent" isn't a third exactly, but no matter ...

[tenrec]

33% = one third
air conbustion type = steam
don't know about the random "r" sorry

[tenrec]

combustion ^

4d (clue reads "...composition type")

Thirdstream (style of music; 'air' as tune, melody) - 'third' (33%) + 'stream' (burn)

Thank you all for clarification..."combustion" was my typing error 'cos I knew it should have read "composition" Thanks once again.
