A series of experiments of both singlephase gas and gascoal mixture flows through the venturi were carried out, and the distribution of pressure, volumetric loading ratio and superficial gas velocity were obtained and compared. The results show that a sharp decrease in static pressure and volumetric loading ratio was observed inside the ...

Coal mills are used to grind and dry the raw coal containing moisture and to transport the pulverized coal air mixture to the boiler. Poor dynamic performance of coal mill causes difficulties in maintaining the frequency, boiler pressure and temperature of the plant. This paper presents development and validation of coal mill model for improved coal mill control. The parameters required to ...

bed scrubbers, spray tower scrubbers, and tray tower scrubbers. Venturi scrubbers may also function as gas absorbers; however, they are usually designed for control of particulates rather than acid gases or SO 2. Gas and liquid flow through an absorber may be cocurrent flow, counterflow, or crossflow.

Solids operations demand special attention when simulating a process because more experimental information is required. These operations are not usually covered in undergraduate level courses or even in industry technical courses considering that usually oil and gas simulations are more common and in those cases solids presence is neglected.

Install Flow Measuring Venturi's or Flow Nozzles, and perform "Hot — K" calibration checks. We have done this for decades and I know of some flow nozzles installed in the mid 1980's, when I was with Flame, that still have the same reliable and accurate "K" factor. Not the least expensive but, they work, are accurate, and reliable.
