Abstract

The current research consists of finding ways to measure the distribution of air and coal between feeder lines set up in parallel connection, from the same grinder, and of achieving a good distribution of these flows.

This study has shown that the location of the collectors influenced the information collected. It was noticed that, for the same power supplied, the signals obtained were different, depending on the type of coal used. This proves that the set up of the collectors would not be constant but would depend on the coal used. During the trials, the gap between the information given by the collectors and the real power supplied is quite important. Therefore no conclusions can be drawn from these trials. However, for all these trials, we could note that the collectors gave similar signals from one given location. These signals have the same profile as the reference signals, but the values are less in comparison with this reference signal. We therefore think that the technique of measurement has to be explored further and it is in fact the electronic part of the collectors tested which is not adapted to the measurement carried out. After the electronic part of these collectors has been set, it was not possible to change it. .
