Abstract

Mineral additives and a method for operating a waste-to-energy furnace are provided in order to improve its operational performance and availability, increase the lifetime of the combustor building materials (refractory walls and heat-exchanger metallic tubes) and flue gas treatment equipment, improve ash quality, reduce emissions and avoid combustion problems such as agglomeration, slagging, deposition and corrosion. A method for operating a waste-to-energy furnace, such as a fluidized bed reactor, pulverized-fuel combustor, grate combustor includes introducing mineral additive into the furnace. The method further includes heating at least a portion of the mineral additive either intimately in contact with the fuel, such that the ability of mineral additive to induce crystallization of the surface of forming ashes is enhanced, or minimizing the contact of the mineral additive with the fuel and the forming ashes, such that the solid-gas reactions between the mineral additive and the volatile compounds in the flue gas are favored and the mineral additive power to capture at least a portion of the inorganic volatile compounds present in the furnace is enhanced.
