In addition, the sampler provides fuel savings by minimising excess air. It reduces wear in pulverizers and enhances control of firing conditions when testing new coal types. Based on electronic signals from the built-in scale weighing the sample, the PLC calculates the total mass flow of pulverized coal in the complete cross section.

 · Hi, I'm looking to compare different types of pulverized coal samplers. If anyone knows of any manufacturers please let me know. (I want to spec out something that would suit the coal pipe velocities at our plant (up to 35m/s) as well as the high moisture content of our coal (could be up to 35%). We currently have a MW unit for sampling, which seems to be su
