Power Catalog TOC - Air Monitor Corporation. data from a Pf-FLO coal flow measurement system allow further optimization of primary air by providing the means of customizing a mill.
Measuring Coal Pipe Flow Coal pipe flows can only be balanced and optimized when they are measured. Until you have confidence in your coal flow measurements, tuning the pul-verized coal boiler is simply guesswork. The right way to balance furnace fuel flows is to establish solid baseline performance by proper measure-
Designed for applications where the presence of airborne particulate might impair the measurement accuracy of Air Monitor's Combustion Air Station or VOLU-probe array. Pulverized Coal Flow Measurement: Pf-FLO: Developed to determine the mass flow and distribution of pulverized fuels in the individual pipelines from the coal mill to the burner.
The first phase consisted of commissioning the coal flow and air flow measurement systems and subsequent continual A/F balancing through automation of Secondary Air flow actuation systems.
Manage mill heat balance and mill dynamics; Reduce boiler load swings; Two independent measurement technologies. MECONTROL Coal utilizes two independent technologies to measure the mass-flow rate in pulverized coal pipes. The velocity measurement uses the time of flight of unique signal patterns created by particles contained in the gas.
Balancing Coal Pipes Power Engineering. In a typical coal mill, primary air (PA) is used to both dry the coal and transport it to the burner(s). measuring dirty air flow or the air in a coal pipe laden with coal .
