Title:
COMBUSTION APPARATUS AND COMBUSTION METHOD
Document Type and Number:
WIPO Patent Application WO/2019/058563
Kind Code:
A1
Abstract:
Provided are a combustion apparatus and a combustion method with which it is possible to suppress, as much as possible, generation of nitrogen oxides and incomplete combustion of ammonia. This combustion apparatus 6A is able to co-combust pulverized coal and ammonia within a furnace. The combustion apparatus 6A is provided with a first nozzle 175 and one or more second nozzles 173B. The first nozzle 175 has a first jet orifice 175h through which pulverized coal is jetted out toward the interior of the furnace. The second nozzles 173B are disposed around the first nozzle 175. Each of the second nozzles 173B has a second jet orifice 173h through which ammonia is jetted out toward the interior of the furnace. The second jet orifices 173h of the second nozzles 173B are each opened in such a manner as to cause combustion flames of ammonia to be jetted in a direction tangential to a virtual circle centered on a central axis aligned with the jetting direction of combustion flame of the pulverized coal, and in such a manner as to be slanted toward the jetting direction side of the combustion flame of the pulverized coal.
