Abstract

PURPOSE:To homogenize mixing and agitating of fluid medium and objects to be incinerated and improve a combustion efficiency by feeding the objects to be incinerated through a feeding tube being arranged coaxially with a jet air feeding tube at a central portion of a bottom of a perforated plate. CONSTITUTION:A jet air feeding tube 8a is disposed coaxially within a feeding tube 9a for objects to be incinerated provided at a lower central portion of a perforated plate 1. A circulating stream a is obtained in a fluid medium 3 by circulating air supplied through a circulating air inducing tube 7 and a jet stream b is given by jet air supplied through the jet air feeding tube 8a. The objects to be incinerated such as EP ash and the like are supplied into a fluid layer 3 effecting complicated motions due to the circulating stream and the jet stream.
