Abstract
The fusion point of coal ash in a boiler is reduced by introducing a boron-containing compound into a boiler containing coal ash and mixing the compound and the coal ash. Preferably the compound is introduced into the furnace box of the boiler as an intimate mixture of pulverized or crushed coal and the compound, the coal being intimately mixed with the compound prior to introduction of the mixture into the furnace box.
