Modelling fluidized dense-phase pneumatic conveying of fly ash

A typical schematic of the test set up used for fly ash conveying is shown in Fig. 1.Kirloskar made electric-powered Model KES 18-7.5 rotary screw compressor was used having the capacity of 3.37 m 3 /min of free air delivery and maximum delivery pressure of 750 kPa. Air flow control valve was installed in the compressed air line Fly ash can also be conveyed in different ways. It can be transported using either pressure (positive) conveying or vacuum (negative) conveying. The former uses compressed air at the start of the system to push the ash through the piping while it is “sucked” toward its destination when using the latter.

Figure 1 shows fly ash produced in a typical pulverized-coal-fired utility boiler and collected by an electrostatic precipitator. There are two commonly used methods for removing the fine powdery fly ash from the fly ash hopper of the precipitator a wet method or a dry method [12–15].In the wet method, water is used to flush the fly ash out of the hoppers and the Ash handling is the process of collecting, conveying, temporary storage and transportation of fly ash residue. The ash handling system is designed specifically for transporting hot, abrasive ashes collected from ESPs. It should be able to remove the collected ashes from the hopper without causing re-entrainment into the gas flow.Ash Handling System 產品列表│Tai & Chyun台耘工業
