PURPOSE:To enable a change of combustion volume over a wide range while suppressing generation of harmful gas by a method wherein a total volume and distribution of air supplied into a combustion chamber is made optimum by means of a pressure loss plate and a ramification plate. CONSTITUTION:A pressure loss is changed by changing an interval between the pressure loss plate 11 and an air regulating plate 9. The ramification plate 12 connected to the pressure loss plate 11 by a connection rod 13 regulates the pressure loss by the interval between the plate 12 and an air hole 10A provided in a partition plate 10. At a maximum combustion, the interval between the ramification and partition plates 12 and 10 is increased to decrease the pressure loss so that the air supply from a small hole of an inner flame cylinder 4 above the partition plate 10 is increased. On the contrary, at a minimum combustion, the interval between the two plates 12 and 10 is decreased so as to decrease the air amount to be supplied from the small hole of the inner flame cylinder 4 while increasing the air amount to be supplied through a small hole formed in the lower part than the above hole. |
