【発明の名称】高発光火炎を発生させる方法および装置
Document Type and Number:
Japanese Patent JPH04500265
Kind Code:
A
Abstract:
A burner (10) and method is disclosed in which a first oxidizing gas (14) containing a high oxygen concentration is injected as a stream into the central zone of a combustion tunnel (12), and part of the fuel (18) is injected (19) into said central pyrolysis zone to mix with said first oxidizing gas to create a highly luminous, high temperature flame core containing microparticles of carbon of the proper size for maximum luminosity and high temperature, and a relatively small amount of hydrocarbon radicals. In addition, the remaining part of the fuel is injected (20) in a plurallity of streams about said flame core to mix with a second oxidizing gas (15) containing a lower oxygen concentration than the first oxidizing gas and injecting said second oxidizing mixture about said flame core and said remaining fuel flow to mix with said remaining fuel flow. This creates a plurality of fuel lean flames which are directed toward said luminous flame core to form a final flame pattern having high temperature, high luminosity and low NOx content.
