かることができる。As described above, the present invention has the following effects. That is, in the embodiment of FIGS. 1 to 5,
As for combustion at low temperature, stable combustion can be obtained by the flame stabilizer, and at the same time, a small amount of air is ejected in two steps from the air ejection part and the air ejection part, and diffusion slow combustion is executed while the gas in the furnace is accompanied. because, not only the occurrence of the NO X is suppressed, emissivity is high, heating time is shortened. At high temperatures, the flame stabilizer is not used, and air is ejected in two stages from the air ejection part and the small amount air ejection part, so the flame emissivity is high and the thermal efficiency is increased, and at the same time, the gas and air are ejected separately. Therefore, the diffusion slow combustion can be executed in the furnace while the gas in the furnace is being circulated, and NO X can be reduced. Further, also in the embodiment of FIGS. 6 and 7, it is possible to execute the combustion at the low temperature and the combustion at the high temperature by simply rotating the flame holding plate, and at the time of the combustion at the low temperature and the combustion at the high temperature, Complete two-stage combustion can be performed, and NO x can be reduced.
