Benefits of technology

The invention aims to create a combustion apparatus that reduces the production of nitrogen oxides (NOx) by giving more time for the fuel and air to mix and blend evenly. By extending the mixing time, the fuel and air can be thoroughly mixed, which reduces the amount of NOx produced during combustion.

Problems solved by technology

However, multi-staged combustion lengthens flame and makes a structure of a combustion apparatus complicated.

Abstract

There is provided a combustion apparatus for reducing generation of NOx by securing more time for mixing fuel and air and uniformly mixing fuel and air.The combustion apparatus includes: a modifying part configured in the center to modify supplied hydrocarbon-based fuel and air and discharge high temperature modified gas including hydrogen to an outlet; and a supply part configured at an outer side of the outlet to jet fuel and air to one side of the modified gas discharged from the modifying part to form a flame at a position spaced apart by a pre-set distance from the outlet.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority to and the benefit of Korean Patent Application No. 10-2012-0086479 filed in the Korean Intellectual Property Office on Aug. 7, 2012, the entire contents of which are incorporated herein by reference.BACKGROUND OF THE INVENTION[0002](a) Field of the Invention[0003]The present invention relates to a combustion apparatus for reducing generation of NOx by forming flame at a position distant from an outlet by jetting a gas including high temperature hydrogen generated by modifying hydrocarbon fuel.[0004](b) Description of the Related Art[0005]A general combustion apparatus is configured to make supplied fuel and air meet in the interior or exterior to form a diffusion flame. Here, a generation rate of NOx (or generation of NOx) may differ according to a mixture degree and a mixture speed of fuel and air.[0006]In order to reduce generation of NOx, a combustion apparatus for jetting air or fuel by multiple stages...
