operating coal fed boilers depends on the design, condition and maintenance of the coal feeders. Stock® gravimetric feeder belts are developed by a research staff in our full scale testing facility. Actual AccuCheck™ Roller Test Chain tests proved the effect of belt characteristics on the weighing accuracy of the feeder.
Gravimetric 2. Volumetric feeding. In most, plant gravimetric type feeding is used as it's the most accurate measurement technique. As it uses the signal of the load cell to measure the coal weight the measurement will never deviate from density changes. But in the volumetric method of measuring the density impacts the accuracy of coal being ...
