Tachometer Coal Feeder

Gravimetric and Volumetric Coal Feed Systems for Boilers

The gravimetric feeder compensates for the variation in bulk density and feeds a fixed weight of coal in response to a boiler fuel demand. This ability to accurately weigh the coal provides significant improvement over volumetric types in terms of matching the fuel delivered by the feeder to the actual process energy required on coal …

Stock Coal and Limestone Feed Systems

the standard for coal feed systems. Volumetric / CVF For those applications where weigh-ing the coal is not desired. Stock volumetric feeders are designed to reliably and safely deliver coal to the boiler and are built in the same tradition as the Stock gravimetric feeder. They are both built to deliver many years of dependable service.

Armature Feedback vs Tachometer - Electric motors ...

22/02/2009· Armature Feedback vs Tachometer Thedroid (Electrical) (OP) 18 Feb 09 18:41. I'm working with a weighfeeder that uses a 3hp 180V 1750rpm DC motor controlled by a Bardac speed control. The Bardac always used tach feedback for regulation, and we have been instructed to remove the tach and switch the controller over to armature feedback. This weighfeeder regulated the amount of coal …

Speed Switch on a Coal Feeder - Electro-Sensors

Coal Feeders convey a uniform feed rate of crushed coal to pulverizers that then reduce the fuel to powdered form before it is blown into boiler furnaces.Coal Feeders are commonly used in the power generation industry. Electro-Sensors' Speed Switches are used on Coal Feeders to monitor critical speed, and guard against slowdown or stoppage that can result in costly process downtime, machine ...

Weighing Accuracy Basics | MERRICK Industries, Inc.

Modern tachometers should be able to discern a belt travel of approximately 1mm per pulse. Additionally, two channel encoders and special electronics in the feeder controller allow for ‘filtering out’ of speed pulses from the tachometer that represent backward travel of the belt due to oscillation or vibration. Therefore, only pulses that ...
