Abstract:
PROBLEM TO BE SOLVED: To prevent emissivity of flame from decreasing upon combusting carbon fuel mixed with low carbon fuel.SOLUTION: There is provided a combined combustion furnace comprising a furnace, a first burner that injects carbon fuel to the furnace to burn the same, and a second burner that injects low carbon fuel of a lower carbon concentration relative to the carbon fuel to the furnace to burn the same.
