Characteristics
Nozzle-mixing type burner. Very stable combustion can be obtained even if with excess air. As high-speed combustion mixes fluids in the furnace, heating is uniform. Further, a high turndown ratio is so big that it is possible to regulate the control of temperature to the extent of low temperature.
