초록

Combustion of hydrocarbon liquids and solids is achieved with less formation of NOx by feeding a small amount of oxygen into the fuel stream.

대표
청구항

What is claimed is: 1. A combustion method that reduces the amount of NOx emitted comprising: providing a combustion device that has a primary combustion zone and a burn out zone; feeding air, and nonaqueous fuel that contains bound nitrogen and comprises pulverized coal, through a burner into said primary combustion zone; and combusting the fuel in a flame in the primary combustion zone that has a fuel-rich zone, while feeding oxygen into said fuel by injecting it directly into said fuel in said primary combustion zone as said fuel emerges from said bu...
