PURPOSE:To promote automatic adjustment for flow rate of burner during starting operation and stopping operation by a method wherein a flow rate in a burner is increased or decreased under a specified ratio in response to a temperature at furnace outlet or elapse time and at the same time amount of dust and volume of combustion air are adjusted in reference to the temperature at the furnace outlet. CONSTITUTION:A burner control device 8 decreases continuously or intermittently fuel flow rate for a burner 3 under a certain specified ratio in response to a signal from an upper control device 12. In turn, a feeder control device 6 performs controlling of burner and controls speed of feeder 1 or its ON-OFF condition, and adjusts amount of dust fed into the incinerator. A control device 9 for opening degree of damper controls the damper to open it under a specified ratio in respect to gas temperature at the outlet of incinerator. Thereby, it is possible to provide automatic adjustment for amount of dust and volume of air as well as flow rate of the burner during starting and stopping operation, respectively. |
