<P>PROBLEM TO BE SOLVED: To provide a combustion burner of a combustion chamber capable of forming stable flames even when combustible gas generating by gasification of waste has low calories. <P>SOLUTION: The burner includes an upper air chamber 5, a lower air chamber 6, a left air chamber 7 and a right air chamber 8 for taking in combustion air, surrounding an outer periphery of a combustible gas flow passage 3 where combustible gas is introduced. Each air chamber is partitioned by a straightening plate 9 having openings 10 to distribute the combustion air. A slit type combustion air discharge nozzle 17 is disposed in each of the downstream of the left air chamber 7 and the downstream of the right air chamber 8. Branch posts 15 for branching the combustible gas flow passage are disposed near an exit of the combustible gas flow passage 3. Burner tile 12 are disposed as spaced from the branch posts 15, and a plurality of burner ports 14 each including a premixing region for mixing the combustible gas with air are formed between burner tiles 12. One burner port in the plurality of burner ports is used as an ignition burner port where the premixing region is expanded by extending the burner tile 12a. <P>COPYRIGHT: (C)2012,JPO&INPIT |
