The Pulverised Fuel Sampler Automatic (PFSA) is a portable unit with automatic operation for extraction of a representative physical sample from the full cross section of a fuel pipe according to the international standard ISO 9931.
The PFS-A is primarily used to determine the fuel mass-flow in the pipe.
For optimal measurements the PFSA should be used together with a M&W Dirty Air Pitot (DAP) or Dirty Air Pitot Laser (DAPL) to ensure a fully isokinetic sample. By using the DAPL the PFSA can receive the data directly via Bluetooth.
The PFSA consists of a portable aluminum control box, a sampling unit (power driven sampling device), a high efficiency precipitating cyclone, a sample bottle, a reinforced compressed air hose, a power supply cable and a connecting cable for sampling lance.
The sampling lance is inserted into the fuel pipe through a Dustless Connection (DC). A multi-point sampler extracts a representative sample from 64 sampling points evenly distributed over the cross-section of a circular pipe.
The sampling is started from the operator panel in the control unit and a sample is extracted during a four minutes period. The sample extraction is done automatically, each time providing a full and precise sample of fuel, independent of the human factor. To ensure an isokinetic sampling, the air velocity is maintained at the same level as the air velocity in the transport pipe all through the sampling period.
The sample is weighed on the built-in scale. When the weight of the sample and the dimension of the pipe are registered on the operator panel, the flow (t/h) is calculated, and the value is displayed on the operator panel.

Options
1. The PFSA can be delivered with a Snap Lock Dustless Connector (PFSA-SL). This product has been developed by M&W in order to help customer to save time and provide an easy way to secure a connection between the fuel pipe and measuring instrument. The design enables insertion of the measuring instrument into the fuel pipe with internal over-pressure which reduces leakage of coal-dust and provides a gas tight sealing.
