Title:
ROTARY KILN
Document Type and Number:
Japanese Patent JP2017032231
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a parallel flow heating type rotary kiln capable of heating and processing while controlling a material within a predetermined temperature range, even when variation occurs in a property of the material, a supply amount and the like.SOLUTION: A parallel flow heating type rotary kiln 1 which adopts exhaust gas temperature control includes material temperature sensors 22a to 22c for detecting material temperature flowing down in a kiln, in a kiln body 2, and also includes material temperature/burner air ratio controller 24 for adjusting a burner air ratio by increasing/decreasing a secondary air amount which is supplied to a burner 5, based on a material temperature value detected by the material temperature sensors 22a to 22c. Then, a burner combustion amount is adjusted by the exhaust gas temperature control capable of controlling the material temperature at the exhaust gas temperature or lower, and in the case where sudden change occurs in the material temperature, the secondary air amount to the burner 5 is increased/decreased according to the change amount accordingly. Thus, flame temperature is adjusted irrespective of the burner combustion amount by adjusting the burner air ratio, and thereby, the material temperature deviating from a predetermined temperature range is suppressed.SELECTED DRAWING: Figure 1
