Grinding and combustion characteristics of woody ... ScienceDirect
The mill load is changed between 65% and 80% of full capacity with load changing rate of %/min. and 3%/min. Time histories of the flow rates for combustion air, primary air, oil and wood pellets as well as mill differential pressure and oxygen concentration in flue gas are plotted in Fig. 7 (rate of load change %/min.). Stability of mill ...
