Pulse Combustor NOXAs Affected by Fuel-Bound Nitrogen

Microinjection Air/fuel Premixer and Combustor

Gas turbines are being utilized in a variety of applications (electric power production, jet engines, etc.) Modern power turbines have the highest operating efficiencies and turn out the fewest pollutants among major combustion energy converting devices. The power generation industry is faced with increasingly stringent emissions requirements for ozone precursors, such as nitrogen oxides and ca...

Use of Symbol Statistics to Characterize Combustion in a Pulse Combustor Operating Near the Fuel-Lean Limit

We apply symbol-sequence analysis to pulse-combustor oscillations to characterize the onset of instabilities near the fuel-lean limit. Using data from a laboratory combustor, we demonstrate that such techniques can be very useful for finding and classifying complex pressure patterns which can be precursors to misfires and flameout. On-line diagnosis of these instabilities could facilitate activ...

Combustion of Reformed Gas and Liquid Fuel in Crgt Combustor

Original scientific paper Numerical simulations of four combustion processes in a dual-fuel combustor of chemically recuperated gas turbine (CRGT) were carried out in this work. The fuels in the four combustion processes were liquid fuel, liquid fuel + steam, liquid fuel + reformed gas and reformed gas, respectively. The mathematical models adopted for different fuels combustion consist of real...

Ignition and flameholding in a supersonic combustor by an electrical discharge combined with a fuel injector

The paper presents the results of an experimental study of supersonic combustor operation enhanced by an electrical discharge. A novel scheme of plasma assisted ignition and flameholding is demonstrated, which combines a wall fuel injector and a high-voltage electric discharge into a single module. The experimental combustor with the cross section of 72 mm (width)  60 mm (height) and length of...
