CATALYST COMBUSTION BOILER

摘要

PURPOSE: To provide a catalyst combustion boiler which is capable of reducing the rate of NOx generation dramatically. CONSTITUTION: In a boiler which couples a burner 6 connected to a main fuel feed line 14 with a blower 7 which feeds combustion air to the burner 6 by way of a duct 8, a preheating burner 11 provided with a preheating combustion feed line 10 is installed at a specified position inside the duct 8. A catalyst combustion unit 13 is installed to the downstream side of the preheating burner 11 where the burner 6 provided with a catalyst fuel feed line 12 is installed to the downstream side of the catalyst combustion unit 13.
