Premixed Turbulent Combustion
Combustion provides 83% of the energy consumed in the U.S., and natural gas, a traditional energy source for industrial, commercial and residential heating, is a fuel of choice for electricity generation in the form of gas turbines for meeting peak electricity demand.
Researchers in the Advanced Energy Technologies Department have pioneered the development of low-swirl combustion technologies. LSC technology emits several orders of magnitude lower nitrogen oxides and other greenhouse gases, can burn pure hydrogen, and can be scaled to the full range of combustion applications, from residential boilers and furnaces, to medium-range industrial dryers, to power-plant scale gas turbines.
The low-swirl injector (LSI) for near-zero emissions gas turbines in power plants is an R&D 100 award winner.
