Brown coal behavior

Correlations Between Petrographical Properties, Chemical Structure, and Technological Behavior of Rhenish Brown Coal... 

The example of application of the statistical prediction method represented in Figure 4 contains a Czechoslovakian brown coal of group 1 which experience has shown to be a particularly vicious fouling coal and a GDR brown coal of group 3 which tends toward behavior of a salt coal but whose operational behavior, while complicated, can be controlled. The values calculated for fg and fp coincide with practical experience while the parameter Rg indicates that the Czechoslovakian coal is harmless whereas the GDR coal is characterized as uncontrollable by available technologies. 

Table 6.26 shows operational data from several plants using the FBDB technology. It is obvious that in the case of low-rank coals (lignites and brown coal), the CO2 content of the gas is slightly elevated as it is at increased pressures (Ruhr 100). The behavior of all other given figure is explained earlier.
