The Pulverized Fuel Sampler PFS is a portable unit designed for sampling of pulverized fuel in the transport pipes between mills and burners. The PFS complies with the ISO Standard 9931 for sampling of coal conveyed by gases.

     The equipment consists of a sampling part, a control unit and a filter package.

     The sampling part is introduced into the coal pipe through a fixed mounted airlock, and the sample is collected in a container attached to the sampling part via a cyclone.

     Why an M&W sampling device?

• Demand for a sampling procedure which can be performed independent of the operating person (no human error) has paced the development of the PFS-A
• The number of operators is reduced from two to one.
• The Snap-Lock by M&W will reduce time spend on each sampling.

     The sampling probe is rotated by an electric motor.

     The control unit is equipped with a PLC which controls the isokinetic velocity of the extraction air as well as the performance of the complete sampling cycle.

     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 (t/h).

     We believe that working with the right information, is the best way you can optimize your combustion process. The coal flow balance and mill performance are important factors in this process.

     Getting your coal dust samples for fineness control and coal flow balancing is often considered as a “dirty job”, which no one really enjoy doing. The result is that his task is not performed as often as it should be.
