Since it supplies NO and completely burns the combustibles, NO
It is possible to significantly suppress the x generation cliff, prevent the discharge of combustible substances, and prevent air pollution without causing any adverse effects such as burnout on the Nariko heat a4 or the air preheater 13. In addition, since the first combustion exhaust gas DI is passed many times through the incinerated ash A in the ash flow path 27 guided by the guide plate 26 arranged in a louver shape in the ash preheater, the first combustion Exhaust gas D1
can be effectively transferred to the incinerated ash A, the amount of heat supplied by the melting burner 2 can be reduced, and the thermal efficiency of the melting furnace 1 can be improved. Furthermore, since the incinerated ash A is heated in the secondary combustion chamber 8 by the counterflow of the first combustion exhaust gas D1 and the secondary combustion flame, thermal efficiency can be further improved. In addition, since the molten slag B is discharged from the slag outlet 6 to the slag cooling chamber 7 together with the second combustion exhaust gas D2 which is a part of the combustion exhaust gas, there is a problem of blockage of the slag outlet 6 where the molten slag B is cooled and solidified. can be prevented.
