わめて向上する。As described above, the present invention has the following effects. Air and fuel are jetted directly into the furnace,
In order to carry out a large amount of exhaust gas recirculation in the furnace compared to a normal burner before the flame is generated and while continuing combustion,
Not occur locally high temperature part, it is possible to suppress the generation of the NO X to a low level. Since the burner tile is unnecessary and the heat storage body is located inside the furnace wall, the exhaust gas temperature after exiting the heat storage body is low, and the lining for fireproof insulation of the heat storage body is unnecessary. Since the structure is simplified, the equipment cost can be reduced. No flame has settled in the fuel supply section,
In addition to improving reliability such as avoiding the problem of burnout of the tip, heat storage is effectively performed in the furnace wall, so that thermal efficiency is significantly improved.
