The Combustion Research Laboratory at Berkeley Lab conducts basic and applied research on lean turbulent premixed combustion. This combustion method is fast becoming an important environmental energy technology because it is a simple and effective means to prevent the formation of oxides of nitrogen. Many U.S. manufacturers of heating equipment are developing premixed burners for their heating products. For power generation, lean premixed combustors are being used in gas turbines both large and small. The goal of our research program is to investigate and characterize fundamental fluid processes of flame/turbulence interaction and to apply the knowledge to the development of combustion theories and numerical simulations. We also specialize in the development of novel lean premixed burner concepts and perform applied research to further exploit the potential of using these new burner concepts in practical systems.
