Abstract The classification performance of model coal mill classifiers with different bottom incoming flow inlets were experimentally and numerically studied. The flow field adjacent to two neighboring impeller blades were measured using the particle image velocimetry technique. The results showed that the flow field adjacent to two neighboring blades with the swirling inlet was significantly different from that with the non-swirling inlet. With the swirling inlet, there was a vortex located bet...

Abstract The natural draft dry cooling tower (NDDCT) has been increasingly used in power generation for its merits of excellent water-saving, high energy saving, simple maintenance and long life service. To study the performance of a newly installed 660 MW NDDCT under crosswind condition, a model with scale of 1:200 was built according to the scaling law of geometric similarity. The experiments were set up in self-similar region with high Reynolds to meet momentum similarity, while meeting the s...

Abstract The velocity field between two adjacent blades in a turbo air classifier was measured using the particle image velocimetry (PIV) technique equipped with a self-developed synchronizer. It was found that vortex swirling flow existed between the two blades or in the annular region between the impeller and the side wall. Under a given condition, the swirling intensity was higher while the swirling zone was smaller in the horizontal plane of the upper stream. As the impeller rotational speed...

One of the most important factors for trouble free operation of CFB boilers is the pressure drop of the gas distributor. The pressure drop characteristic of the gas distributor depends on the nozzles used. A modified bell jar nozzle was designed and developed for use with large-scale industrial circulating fluidized bed (CFB) boilers. The nozzle consists of a vertically tapered tube with a larger end at the top, a float which is free to move within the tube and a cover with holes. The pressure d...
