Primary air cylinder 6 is provided around fuel pipe 4. Oil-gas cylinder 7 is provided around primary air cylinder 6. Oil-gas cylinder 7 is connected to mixed fuel producing device 11 via gas header 8. On the other hand, partition wall 12 is provided on the inner side of wall 2, and the gap between these is made as primary air supply passage 13. This is connected to primary air cylinder 6 by means of connecting cylinder 14. Secondary air supply passage 16 is formed between partition wall 12 and refractory wall 5.
