EU Tech – Coalsizer – Coal Fineness Euflame – FEGT Continues Monitoring Fineness Testing and Mill Optimization The coal particle size spectrum has a strong impact on the combustion process. It influences ignition delay, combustion efficiency, LOI, NOx & CO, as well as slagging and fouling. Despite the significance of this property, there has not yet been a robust and easy to handle system for the online measurement of coal fineness inside the pipe. EucoalizerSolution EUcoalsizer solves this problem. The laser based system measures the particle size distribution and the coal as well as PAPF flow. By traversing the lance through the pipe, a particle size distribution along the cross-section of the coal pipe can be measured. The time of transition method covers a very wide range of particle sizes from 20 μm to 4 mm. The simultaneous measurement of coal and air flow proves to be an essential prerequisite for fuel line balancing and coal flow optimization. Specifications The EUcoalsizer system comes turn-key and can be directly applied via an adapter to the coal pipe. The system delivers results on-line and instantaneously. Handling is very easy via an intuitive graphical user interface. The system has many helpful features to support analysis and optimization (report generator, data base, etc.) Rugged industrial design for exposure to highly abrasive flow conditions Effective lance length > 1 m (covering pipe diameters up to ~625 mm 25″) Probe diameter 51 mm (2″) Benefits On-line combustion optimization (reducing LOI, emissions, slagging) Pulverizer performance monitoring Condition-based pulverizer maintenance Coal flow and airfuel distribution tuning Reduction of fuel consumption Real time, dynamic Rosin Rambler chart Accurate airfuel ratio measurement
