Our CEO Hans Georg Conrads talks about On-line measurement and control in PF pipework in August issue of Modern Power Systems magazine.

The conversion of coal firing systems to biomass poses some serious challenges to the operators.  Especially when conventional mills i.e. vertical spindle mills are used, the switch away from coal to biomass results in a radically different behavior of the whole firing system.  The typically emerging problems are mill trips, mill fires, flame shoot backs with the associated thermal damage to burner tips or even complete burner plugging or meltdowns including fires in the transport lines.  The two major difficulties are as follows:

At first the nature of the problems and how to deal with them differs radically from the ones with coal. So different answers are to be found.  

Secondly, as the whole firing system from feeder inlet to burner outlet is a fluid-dynamic black box, it is hard to say where in that complex process the problems exactly start.  They can emerge at different locations in the process any time.
