Abstract
PURPOSE: To obtain the proper air-fuel ratio every each burner by a mechanism wherein wind box dampers at burner inlets are fully opened or closed completely, and used only for changing over systems, and analoglike control dampers are separately mounted to a line common to all burners.
CONSTITUTION: An air duct 5 for combustion is branched into common ducts 4, 4', and the ducts 4, 4' of both systems are communicated with each nozzle. Wind box change-over dampers 3A,3' A,3" A and 3B,3' B,3" B, which are changed over to full admission or full closing, are further installed to the dusts 4, 4' at the inlets of each burner in shapes that correspond to the inlets, and distribution control dampers 4A, 4'B with positions are similarly disposed. Thus, only the distributing control dampers of the common ducts need positioners in this constitution, the dispersion of the quantity of a wind due to the errors of the control of opening by means of the positioners and the errors of the wind box dampers under intermediate opening conditions is removed, and air is uniformly distributed every each burner.
