Sampling and process control systems for coal/biomass fired power plants
The Pulverized Fuel Sampler (PFS) is a manual sampling device, designed for representative extraction of samples (pulverized coal or biomass) from pneumatic transport pipes. The sampling procedure is in accordance with the international ISO 9931 standard.
The sampling lance is inserted through a Dustless Connection into the pulverized fuel pipe. A multi-point sampler extracts one representative sample from 64 sampling points evenly distributed over the cross-section of a circular pipe.
The sampling gas velocity is maintained at the same level as the gas velocity in the transport pipe all through the sampling period, to ensure an isokinetic sampling. By isokinetically extracting the sample, the particulate flow rate can be determined.
The PFS consists of:
1.1 Dustless Connection (optional).
1.2 Sampling Lance (manually operated).
1.3 High efficiency precipitating cyclone.
1.4 Sample bottle (500 ml plastic container).
1.5 Reinforced vacuum/compressed air hose (L = 2,5 m).
1.6 Control Unit.
1.7 Power supply cable without wall plug (L = 1 m).
