As a furnace designer, Technip is faced with the challenge to meet ultra-low NOx emissions when designing or revamping ethylene cracking furnaces and steam reformers. The fundamental modeling approach developed by Technip as a mandatory tool when designing critical furnaces is presented. The application of the combined CFD model to design a modern high-flux GK6™ ethylene furnace equipped with ultra-low NOx burners is described. The model has been validated by comparing results with those obtained under controlled laboratory conditions. The Sydney bluff-body burner data are used. This burner produces a diffusion flame from a methane/hydrogen mixed fuel. The model results compared very well with published laboratory data. This is an abstract of a paper presented at the 2010 Spring National Meeting (San Antonio, TX, 3/21-25/2010).

Abstract
As a furnace designer, Technip is faced with the challenge to meet ultra-low NOx emissions when designing or revamping ethylene cracking furnaces and steam reformers. The fundamental modeling approach developed by Technip as a mandatory tool when designing critical furnaces is presented. The application of the combined CFD model to design a modern high-flux GK6™ ethylene furnace equipped with ultra-low NOx burners is described. The model has been validated by comparing results with those obtained under controlled laboratory conditions. The Sydney bluff-body burner data are used. This burner produces a diffusion flame from a methane/hydrogen mixed fuel. The model results compared very well with published laboratory data.
