Development of an Ultra-Low NOx Gaseous Fuel Burner for OTSG Applications

Paper from the AFRC 2016 conference titled Development of an Ultra-Low NOx Gaseous Fuel Burner for OTSG Applications

The paper presents an overview of the development process used to design improvements to an Ultra-Low NOx gaseous fuel burner for once through steam generator (OTSG) applications. It discusses the use of Computational Fluid Dynamics (CFD) for the prediction of key performance metrics such as NOx emissions and vessel heat flux profiles and simplifications in CFD processing such as the use of steady state solvers and the use of reduced chemistry sets. Results of CFD modeling are compared with data collected from large scale combustion tests.
