Effect of oxygen-staging on fluidized preheating combustion of pulverized coa...

The results showed that the increase of excess oxygen coefficient of the primary air ( lambda Pr ) decreased the temperature difference at each measuring point in the circulating fluidized bed, promoted the production of coal gas. As the lambda Pr increases, reducing the excess oxygen coefficient of the secondary air ( lambda Se ) or increasing ...

Unsteady fluidic oscillators for active controlling boundary layer separation...

This study used large eddy simulation ( LES ) to investigate the control mechanism of a fluidic oscillator in the suppression of non-reattachment separation of a boundary layer from an ultra-high-lift, aft-loaded. Which promoted the laminar boundary layer to produce bypass transition and significantly improved the aerodynamic performance of the ...

Effect of post-combustion air distribution on NOx original emission and combu...

Coal slime has been discharged or piled up on the spot as solid waste for a long time, causing a lot of waste of resources and environmental pollution .A 75 t/h circulating fluidized bed ( CFB ) boiler with post-combustion technology was built for combustion of coal slime. To explore the post-combustion technology and the influences of post-comb...
