Low-Nox Premixed Combustion of MBtu Fuels Using the ABB Double Cone Burner (EV Burner)

Numerical Investigation on the Flow, Combustion and NOx Emission Characteristics in a 10 MW Premixed Gas Burner

The characteristics of the combustion temperature, flow velocity, CO distribution and NOx emissions of a 10 MW gas burner at different primary to secondary air ratios are numerically studied using computational fluid dynamics software Fluent. The results indicate that the primary to secondary air ratio in gas burner determines the combustion quality through influencing some parameters directly,...

Effects of Flame Temperature on Combustion Instabilities of a Premixed Burner

Combustion instabilities in gas turbine has been a major setback in the quest for efficient and clean combustion. Accurate characterisation and prediction of these disturbances is required to suppress them either at the design stage or in a close loop control when the system is in operation. The use of flame transfer functions has been a common approach in different literatures. Flame temperatu...

The Simulation of Biogas Combustion in a Mild Burner

This paper discusses the design and development of moderate and intense low oxygen dilution (MILD) combustion burners, including details of the computational fluid dynamics process, step-by-step from designing the model until post-processing. A 40 mm diameter bluff-body burner was used as the flame stabilizer. The fuel nozzle was placed in the center with a diameter of 1mm and an annular air no...

Simulation of Nitrogen Emissions in a Premixed Hydrogen Flame Stabilized on a Low Swirl Burner

There is considerable interest in developing fuel-flexible, low emissions turbines for power generation. One approach is based on burning a variety of lean premixed fuels with relatively low flame temperatures. Such flames can be stabilized in a low swirl burner configuration, for example, using a variety of fuels such as pure hydrogen and hydrogen-seeded hydrocarbon mixtures. However, many hyd...
