Experiment of Axial Flow Cyclone Dust Collector in Furnace for Industrial Boiler
Efficient dust emission control of axial flow cyclone dust collector for industrial boiler is proposed by experimental study.From research work on the effective factors of collection efficiency and drag coefficient,which are outlet diameter,inlet blade angle,and length of steady flow etc,it is derived that the proper outlet diameter is 0.7 times the size of the diameter of separator,the appropriate inlet blade angle is 60 ° for drag coefficient trends great while inlet blade angle goes small,and the length of steady flow rests with weighing the effect of collection efficiency and drag coneffcient.Therefore,the configuration of axial flow cyclone dust collector suitable for industrial boiler application is achieved,which applies experimental and research information to the improvement of industrial boiler.
The flow through a double throat nozzle is computed using the complete time-dependent compressible Navier-Stokes equations. The computations were performed by using an existing working code, which uses MacCormack’s explicit finite difference scheme. There were no special modifications made in the code for this particular application. The computations were performed on a Cyber 84 5 computer and a CRAY XMP-48 computer using three different grid sizes.
