Abstract
PURPOSE: To provide an arrangement for the boiler combustion apparatus equipped with an over-fire air feeding means (OFA), which is capable of starting the boiler rapidly, reducing the amount of NOx contained in the exhaust gas and prolong the service life of an OFA nozzle, by providing a starting burner in the OFA means.
CONSTITUTION: In the boiler equipped with a main burner (load burner) 2 disposed in a main burner wind box 1 and an OFA4, the starting burner 3 is attached to the OFA4. Operation of these two burners is controlled by controlling a damper 6 appropriately to meet the load. The starting burner 3 is constructed as one 11 that can be moved telescopically by a driving means 14, as shown in the drawing, so that it can be projected to the position shown in the drawing at the time of starting operation of the boiler. Further, an air nozzle 8 is attached to the front end of an OFA wind box 7 in the manner that it can be tilted vertically through an angle of about 30° by a tilting means 10, and a flame holding means 12 for the starting burner is provided inside the air nozzle 8.
