摘要： PURPOSE:To enable a stable combustion to be attained by a method wherein a flame hole structure of a thin flame burner is provided with thick gas recesses, the recesses are communicated with an adjoining thick flame burner then e thick flame is formed between the thin flames. CONSTITUTION:A thin flame is formed above a flame hole structure with thin mixture gas supplied to a thin flame burner 2 during combustion and thick flame is formed on a flame hole structure 11 with the thick mixture gas supplied to a thick flame burner 3. The flame hole structure 11 of the thin flame burner 2 is provided with thick gas recesses 13 so as to divide the thin flame holes and form them. Thick gas is flowed from the thick flame burner 3 near the thick gas recesses 13 so as to form the thick flame on the thick gas recesses 13. With such an arrangement as above, the thick flame is formed between the thin flames of the thin flame burner 2, resulting in that it is possible to restrict the lifting of the thin flame, the vibratory combustion and to make a stable combustion.

CONSTITUTION:A combustion pipe 11 is comprised of a pair of right and left outer walls forming a throat part and a flame port, and of a central separating wall 12. A passage is divided by the separating wall 12 into a right one and a left one, i.e., a rich gas passage 13 and a lean gas passage 14, respectively. Flame ports 15 at the separating wall 12 are formed into corrugations. In addition, rich gas flame ports 16 and the lean gas ports 17 are alternatively formed. With such an arrangement as above, two kinds of rich and lean gas flames are alternatively formed to improve a flame holding characteristic. In turn, a pressure reducing wall 21 is arranged at an outside part of the flame port of the combustion pipe 1 through a flame holding gap 20, and a through-pass hole 22 for use in supplying rich gas from a rich gas passage 13 into the pressure reducing wall 21 is formed at a lower part of the rich flame ports 16. With such an arrangement as above, the rich gas flame is generated above the flame holding gap 20 so as to further improve the flame holding characteristic.

摘要： PURPOSE:To improve the holding effect of main flames in a thick and thin fuel combustion type combustion apparatus, and to reduce the loads on burner ports and combustion noise. CONSTITUTION:A thin fuel-air mixed gas passage 2 is separated from a thick fuel-air mixed gas passage 3 by a partition wall 4. A contact edge 5 of the partition wall 4 with a burner port plate 1 is formed into a blade-like shape. Thereby, main and auxiliary flames formed on the burner port plate 1 are not separated from each other and the holding effect of main flames is improved, resulting in stabilization of main flames. Moreover, as an area on the burner port plate 1 where flames are not formed can be eliminated, the area efficiency is improved and the loads on burner ports and combustion noise are reduced.
