This paper describes some of the efforts made at the Leland Olds Station to cope with the problems created from high sodium content coals. Such coals have historically presented superheater fouling problems for utilities; ash deposits from high sodium coals have a very high sintering strength and are very difficult to remove by conventional methods. It is reported that the addition of limestone in the pulverizer unit at Leland Olds and vermiculite ore in the cyclone unit has helped reduce the fouling characteristics of high sodium lignites in North Dakota at an affordable cost.
