Abstract

Combustion apparatus (1) for reducing generation of NOx by securing more time for mixing fuel and air and uniformly mixing fuel and air and including a modifying part (100) configured in the center to modify supplied hydrocarbon-based fuel and air and discharge high temperature modified gas including hydrogen to an outlet (101) and a supply part (200) configured at an outer side of the outlet (101) to jet fuel and air to one side of the modified gas discharged from the modifying part (100) to form a flame at a position spaced apart by a pre-set distance from the outlet (101).

Description

Background of the invention [0001] (a) Field of Invention [0002] The present invention relates to a method for reducing NO by injecting gas containing high temperature hydrogen produced by reforming hydrocarbon fuels to form a flame at a distance from the outlet x generated combustion equipment. [0003] (b) Description of related technology [0004] Typical combustion equipment is configured such that the supplied fuel and air meet internally or externally to form a diffusion flame. Here, according to the mixing degree and mixing speed of fuel and air, NO x production rate (or NO x generation) may be different. [0005] To reduce NO x Combustion equipment for injecting air or fuel in multiple stages or performing fuel-rich combustion and lean combustion in multiple stages has been developed. However, the multi-stage combustion prolongs the flame and complicates the construction of the combustion equipment. [0006] In an effort to solve this problem, it is possible ...
