We present preliminary results of laboratory tests carried out on moving samples of coal by means of an innovative LIBS system with a large depth of field. The measuring system has been conceived to operate on line in a coal fired power plant. To duplicate at laboratory level the real situation, the coal samples are sequentially positioned under the measuring head by means of a translation/rotation unit that allows reproducing the behavior of the raw coal transported by a conveyor belt Experimental results show that both carbon and hydrogen concentration. as well as the content of some inorganic components (Al, Ca, Fe, Si) can be evaluated with good accuracy.
