Provided are mineral additive blend compositions and methods of operating furnaces to avoid combustion problems such as agglomeration, deposition, corrosion, and to reduce emissions. A method of operating a furnace such as a fluidized bed reactor, a pulverized fuel combustor, a grate combustor, etc. includes introducing a mineral additive blend comprising fuel and clay and a functional mineral into the furnace. The method further includes heating at least a portion of the inorganic compound-containing material and the clay, resulting in at least a partial firing of the clay, the at least partially fired clay, and the functional group. And a step of adsorbing at least a part of the inorganic volatile compounds present in the furnace to the functional mineral and reacting them with ash generated during combustion of the fuel to increase the fire resistance of the ash. . The method further includes removing at least a portion of the at least partially calcined clay and the adsorbed inorganic compound from the furnace. |
