Title:
TURBULENT BURNER CAPABLE OF SIMULTANEOUSLY BURNING NH3 AND PULVERIZED COAL
Document Type and Number:
WIPO Patent Application WO/2023/071260
Kind Code:
A1
Abstract:
A turbulent burner capable of simultaneously burning NH3 and pulverized coal, comprising a primary air channel (1), an annular inner secondary air channel (2), an annular NH3 burning channel (4), and an annular outer secondary air channel (3) that are sequentially arranged from inside to outside. When the turbulent burner works, NH3 and air are burnt in a porous medium burning channel, heat is released, and inner secondary air and outer secondary air are heated. Excessive NH3 can react with NO in flue gas in a combustion area, so as to remove part of NOx. The turbulent burner can the amount of coal used can be reduced, and can reduce the generation of NOx during a coal combustion process.
