WIPO Patent Application WO/2014/014065
Kind Code:
A1
Abstract:
In order to make it possible to efficiently burn fire-retardant fuel by a rotary kiln, a fuel combustion device (201) is provided with a plurality of inside air injection port portions (310) which are disposed in a ring shape at intervals radially inside a plurality of fuel injection port portions (235) and around a virtual axis (O) in a discharge port (g1), and through which air is injected in a spiral diffusion direction (s01) between a rotation direction (t1) around the virtual axis (O) and the outward direction of a radial direction (r1) as going in an injection direction (f1). A predetermined inside injection port gap is formed between two inside air injection port portions (310) adjacent in the direction around the virtual axis (O) such that air present inside the ring shape formed by the plurality of inside air injection port portions (310) and present in the injection direction (f1) goes with and between a plurality of inside air flows injected respectively from the inside air injection port portions (310).
