Combustion apparatus for treating dry distillation gas

Abstract

The present invention intends to provide an improved combustion apparatus with a low risk of a fire and an explosion, in which a nozzle is prevented from being blocked with dust contained in dry distillation gas so that backfiring would not be caused. A combustion apparatus for treating dry distillation gas is thus constructed with a gas pipe for supplying a combustion chamber with dry distillation gas generated during a waste treatment by means of dry distillation and an air pipe for supplying a front edge of the gas pipe with combustion air, wherein the air pipe is placed inside the gas pipe to construct a coaxial double pipe so that it forms a circular combustion nozzle at the front edge of the gas pipe.

       2 . A combustion apparatus for treating dry distillation gas, comprising: a gas pipe for supplying a combustion chamber with dry distillation gas generated during a waste treatment by means of dry distillation; an air pipe for supplying a front edge of said gas pipe with combustion air; and a combustion nozzle formed at said front edge of said gas pipe; wherein, said air pipe is centrally placed inside said gas pipe so as to construct a coaxial double pipe, said combustion nozzle is formed as a circular combustion nozzle at said front edge of said gas pipe, said air pipe is supported to be axially rotatable, and scrapers are further provided with blades of said scrapers being in contact with a circumference surface of said air pipe.
