Measuring Coal Pipe Flow Power Magazine Oct 01 2009 the pitot tube measures clean air flow in a coal pipe based on an internal grid of at least 24 individual measurements representing equal flow areas this measurement is made with no coal Combustion Air Pipe Flow Measurement Vega To ensure an optimum combustion process in a coalfired power plant the amount of air flowing in the pipes leading to the furnace must be carefully monitored a venturi section of the air pipe is a defined constriction in which the pressure drops a few millibars proportional to flow rate How Accurate Primary Airflow Measurements Improve Plant May 15 2006 in fact using the seal air off coal piping flow numbers in table 2 would lead to a very inaccurate calibration actual pa flows would be up to 123 times higher than the reading of the flow Flow Measuremen In Coal Mill Pulverised coal flow measurement in thermal power plant know more state coal mill model development plant measurements such as air flow rate differential pressure across mill etc are considered as inputsoutputs Measuring Coal Pipe Flow Prerequisite to balancing coal flow among coal pipes 3 measure on a grid the pitot tube measures clean air flow in a coal pipe based on an internal grid of at least 24 individual measurements representing equal flow areas this measurement is made with no coal flowing into the pulverizers source storm technologies inc flow
