METHOD FOR OPTIMIZING THE BURNOUT OF EXHAUST GASES OF AN INCINERATOR

摘要

A method for optimizing the burnout of exhaust gases of an incinerator includes introducing a solid material via an inlet into a combustion chamber defining a primary combustion space, combusting the solid material in the primary combustion space, in the form of a combustion bed conveyed over a combustion grate, with admission of primary air, discharging the combusted solid material from the primary combustion space via an outlet arranged opposite the inlet in the conveying direction, combusting the primary combustion gases released during the combustion of the solid material, with admission of secondary air, in a secondary combustion chamber defining a secondary combustion space and arranged downstream of the combustion chamber in the flow direction of the combustion gases, and homogenizing the exhaust gases containing the primary combustion gases in a mixing zone by means of a fluid introduced via a nozzle before entry into the secondary combustion space.

1. A method for optimizing the burnout of exhaust gases of an incinerator, said method comprising:
introducing a solid material to be combusted via an inlet into a combustion chamber defining a primary combustion space; combusting the solid material in the primary combustion space, in the form of a combustion bed conveyed over a combustion grate, arc combusted with admission of primary air; discharging the combusted solid material from the primary combustion space via an outlet arranged opposite the inlet in a conveying direction; combusting primary combustion gases released during the combustion of the solid material, with admission of secondary air, in a secondary combustion chamber defining a secondary combustion space and arranged downstream of the combustion chamber in the flow direction of the combustion gases; and homogenizing the exhaust gases containing the primary combustion gases in a mixing zone by means of a fluid introduced via a nozzle before entry into the secondary combustion space, wherein the mixing zone adjoins the combustion bed at least approximately directly in the flow direction of the exhaust gases, the exit speed of the fluid from the nozzle is about 40 to about 120 m/s, and wherein the nozzle is oriented at an angle from about −10° to about +10° relative to the inclination of the combustion grate.
