PURPOSE:To eliminate instability of a combustion condition occurring due to changes in garbage properties, by a method wherein a correction calorific value of charged solid waste is set through the computation, and a furnace temperature is controlled so that a safe operation can be carried out. CONSTITUTION:A self-correcting device 130 for calorific value, which outputs a corrected calorific value 120 according to a waste charging amount 80, an air discharge 100, etc., is mounted, and a furnace temperature 90 is controlled within an allowable range by means of an air discharge minor control device 50. The corrected calorific value 120 from the device 130 is outputted as it is and as an output of a calorific value operational device 16 except an initial setting time, and a solid waste charge operational device 20 operates a solid waste charge setting amount 80 from said calorific value 70 and an average calorific value of a furnace, meanwhile, an operational device 30 for furnace temperature set value operates a furnace temperature set value 110. The device 50 controls an air discharge 100 so that the furnace temperature 90 becomes the furnace temperature set value 110. |
