Brown coal with moisture content of 65% has been successfully burned for many years in large central atotions in State of Victoria, Australia. Recent severe shortage of black cools has made this brown coal o necessity In industrial boilers generating uoder 20,000 )b per hr of steam. Adopting existing stokers required considerable experimenting. Spreader stokers had no ignition dif* ficultiea and the feor of beery fly*esh emissions did not materialize. A gross grate rating of 600.000 Blu per sq ft per hr resulted from firing unscreened coal, 49% moisture, 2% ash, crushed to about 3*in. maximum size ond possess* ing a high reactivity. Single-retort underfeed stokers with 121 (52) forced-draft fans can fire brown cod of 59% moisture by using (1) thick fuel beds (2) larger coal quantities P0 unit of boiler capacity--about thr*. times normal bituminous feeds (jj close control of sizing--fines, Vfe in* **. below, should not exceed 10% W larger feed screws or greater tt**1 speed for increased feed rotes.
