COMBUSTION CONTROL DEVICE AND COMBUSTION CONTROL METHOD FOR CALCINATION FURNACE OF ROTARY KILN WITH PRE-HEATER

摘要

PROBLEM TO BE SOLVED: To eliminate any bad influence against facility whatever combustion characteristics may be found in combustible waste material and the like and further enable a degree of dissolution of raw material to be kept constant.;SOLUTION: There are provided feeding rate setting means 11 for setting a feeding rate of several kinds of combustible waste materials fed into a calcination furnace; temperature difference detecting means 14 for detecting that a value in which a temperature measured by second measuring means 13 is subtracted from a temperature measured by first measuring means 12 becomes less than a pre-set set value; feeding means 15 for feeding the combustible waste materials into the calcination furnace at a feeding rate; feeding amount adjustment means 18 for adjusting a feeding amount of the combustible waste materials in such a way that a temperature measured by the first measuring means 12 may become a pre-set target temperature; and feeding rate adjustment means 16 for adjusting the feeding rate of the feeding rate setting means 11 upon output of the detecting signal from the temperature difference detecting means 14.;SELECTED DRAWING: Figure 2;COPYRIGHT: (C)2017,JPO&INPIT
