FUEL COMBUSTION DEVICE FOR CEMENT ROTARY KILN

摘要

PROBLEM TO BE SOLVED: To provide a fuel combustion device for a cement rotary kiln capable of efficiently burning a combustible material together with a main fuel in the cement rotary kiln.;SOLUTION: A fuel combustion device 1 for a cement rotary kiln includes a main fuel burner 60 having an annular main fuel injection port 66 for annularly injecting a supplied main fuel, and a combustible material injection nozzle 10 as combustible material injection means for transferring combustible material to a transferring direction with a transferring gas flow and turning the transferred combustible material to a turning direction s with a turning gas flow w to be diffusively injected so that the combustible material reaches the injected main fuel. The combustible material injection nozzle 10 includes a turning injection port 30 tilted to the turning direction s side with respect to a center O of a transfer hole 20.;COPYRIGHT: (C)2016,JPO&INPIT
